One Fully Funded Ph.D. Studentship Available at UCL, London

The Department of Physics and Astronomy, UCL and Synopsys are seeking applications from enthusiastic PhD candidates interested in carrying out fundamental research using quantum mechanical methods in collaboration with an industrial partner. This 3.5 years PhD project will be carried out in the group of Prof. Alexander Shluger at the Department of Physics and Astronomy, UCL in collaboration with Synopsys, the global leader in software for design and verification of microelectronic devices. It will focus on modeling the effects of defects in materials on degradation and dielectric breakdown in nano-electronic devices for future green technologies and artificial intelligence.

Project Overview
The power consumption and reliability of modern nano-electronic devices, such as transistors and memory cells, strongly depend on the defects present in the insulator and at the metal-insulator interface. This PhD project will use computational modelling tools developed at UCL and by the Synopsys QuantumATK team to understand causes of degradation of devices at atomistic level and predict ways of improving their reliability and power consumption. This will involve developing novel methods for modelling the structure and properties semiconductor/insulator/metal interfaces based on atomistic modelling and Density Functional Theory.

Candidate's Profile
Highly motivated candidates from Physics, Chemistry or Materials Science Departments are strongly encouraged to apply for this post. Please note that, due to funding restrictions, only UK citizens and EU citizens who studied in the UK over the last 3 years are eligible for this studentship. The PhD training and research will be carried out at UCL and the London Thomas Young Centre. The starting date of the project is on September 28, 2020.

Application
The closing date for applications is 31st March, 2020. Evaluation of applications will commence immediately, and will continue until the position is filled. Applications and inquiries regarding the vacancy can be made to a.shluger@ucl.ac.uk  (Tel: +44 (0)20 7679 1312).

Three Fully Funded Industrial Ph.D. Studentships Available

The Device Modelling Group at the University of Glasgow, IBM Research Zurich and Synopsys QuantumATK are looking to appoint three Early Stage Researchers to work in the framework of the Marie Skłodowska-Curie European Industrial Doctorate Network on the ‘Defect Simulations and Material Growth of III-V Nanostructures – European Industrial Doctorate’ project.

To apply and learn more.

Project Overview
There is a great interest in integrating compound semiconductors either monolithically or heterogeneously on silicon to exploit their complementary properties. Particularly to exploit the direct bandgap of III-Vs for opto-electronic devices densely integrated with CMOS. In this project we will address the challenges associated with the formation of defects and material growth in compound semiconductors such as III-Vs as well as their impact on device performance. Defects may be exploited in the development of novel devices, but more often we wish to mitigate their deteriorating impact on electro-optic device performance, by growth and materials optimization.

Candidates’ Profile
Three candidates with a master’s degree in physics, engineering or chemistry with knowledge of solid-state physics, materials science or electrical engineering and with an outstanding academic record. The candidates must be fluent in English, have good communication skills and be able to navigate in an international environment.

Individual Projects
ESR1 will mainly focus on aspects related to III-V materials epitaxial growth on silicon, TEM analysis and development of a machine learning algorithm for defect classification. Development of simulation framework to model the electronic and optical properties of individual defects.
Employment: IBM Research Zurich (Switzerland) (22 Months) & University of Glasgow (UK) (14 Months).

ESR2 will explore the role of defects in the context of opto-electronic device performance, this will be done first via simulation where optimized designs will be developed, and later these will be fabricated by the ESR at IBM.
Employment: University of Glasgow (UK) (14 Months), IBM Research Zurich (Switzerland) (22 Months)

ESR3 will develop theoretical models which will describe the complexity of the material growth process and defect formation in III-V materials. Those models will be implemented in state-of-the-art QuantumATK commercial simulation framework.
Employment: University of Glasgow (UK) (12 Months), Synopsys QuantumATK (Denmark) (24 Months)

News and Announcements / Join us for a free webinar on 27Feb on how to simulate interfaces in electronics

« on: January 31, 2018, 11:02 »

Join us for a free webinar featuring a demonstration of simulating interfaces at the atomic scale using QuantumATK (former VNL-ATK).

You can register here.

Interfaces, such as metal-semiconductor, are becoming increasingly more important due to continued down-scaling of electronic devices. For example, the detailed understanding of the metal-semiconductor contact resistance at the atomic scale is necessary in order to tailor the contact resistance of the devices. You can learn more about simulating interfaces with QuantumATK in the  TCAD News, December 2017.

This webinar might also be interesting to researchers/engineers in other application areas than electronics, as simulating interfaces is important when modeling batteries, solar cells and materials in general.

Time:
The webinar will be held twice on February, 27th:
9 am CET (CET - Central European Time, Denmark)
6 pm CET (good time for participants from Americas).

The duration is 1 hour (including 15 min Q&A session).

Presented by: Daniele Stradi, PhD and Petr Khomyakov, PhD - Senior Application Engineers from Synopsys QuantumWise.



Discover the simulation of interfaces with QuantumATK:
- Learn about our state-of-the-art method for simulating interfaces (Density Functional Theory + Non Equilibrium Green's Function method).
- Create and relax the structure of the interface, dope the semiconductor.
- Calculate electronic structure (band diagram) of the interface and the most important parameters that characterize an interface: Schottky barrier and contact resistance.
- Perform a physically sound analysis, compare with experimental results.
- Learn from the Global Foundries and IBM Research study of the TiGe/Ge interface and the Imec study of the TiSi/Si interface, both carried out using QuantumATK.

Afterwards, there will be time for questions and discussion.

For any questions about the webinar, please contact quantumatk@synopsys.com. We look forward to meeting you during the webinar!

News and Announcements / Free-webinar: include electron-phonon scattering effects in device simulations

« on: December 4, 2017, 15:06 »

Synopsys QuantumWise will host a free webinar on how to include electron-phonon scattering effects in large scale atomistic simulations of electronic devices using the Special Thermal Displacement (STD)-Landauer method in VNL-ATK 2017. These effects play a central role in the performance of nano-scale electronic devices, such as rectifiers and transistors.

The webinar will be held TWICE:

1)  December, 14th, 9 - 9.30 AM CET (Central European Time, Denmark)

2) December, 14th,  8 - 8.30 PM CET (Central European Time, Denmark) - good time for participants in Americas

Presented by: Daniele Stradi, PhD and Ulrik Grønbjerg Vej-Hansen, PhD from Synopsys QuantumWise

This webinar is targeted to:

- ATK users who already perform atomistic device simulations;
- engineers/researchers who perform TCAD simulations of devices.

We will cover:
- why electron-phonon scattering effects play a central role in the performance of nano-scale electronic devices;
- how and why the STD-Landauer method works (as an approximation for the current including explicit electron-phonon couplings) for including electron-phonon scattering effects and why it is so efficient;
- how to set up, run STD-Landauer calculations and analyze results, following the case study on a silicon p-n junction: https://docs.quantumwise.com/casestudies/std_transport/std_transport.html
- example applications of the STD-Landauer method for calculating electrical characteristics of semiconductor devices.

Afterwards, there will be time for questions and discussion.

After registering, you will receive a confirmation email containing information about joining the webinar. For any questions about the webinar, please contact info@quantumwise.com.
