General Questions and Answers / Re: Which one would be the better placement option of Target Molecules for a FET ?
« on: May 27, 2025, 11:40 »Hi
I would suggest #1 and let the optimization determine where it will go.
Thanks for your response. It would be great if you can share some scientific reference based on that. Thank you.

General Questions and Answers / Which one would be the better placement option of Target Molecules for a FET ?
« on: May 22, 2025, 07:38 »
Dear experts,
Good morning, hope you are doing well. Which one would be the better placement option of Target Molecules for a FET?
1.For example, as per van der wal force between Target molecules and Graphene FET. Molecule should be placed just above the channel region.
2.Another option is to place the molecule in the channel based on covalent bond between graphene molecule and that target molecules.
Please advise. Thank you.

Good morning , Hope you are doing well. How to extract celllines or protien or DNA or RNA or Aptamer as a biomarker for FET based Sensor?
For Example - https://pubchem.ncbi.nlm.nih.gov/cell/CVCL_0031
Keratin and some other smaller molecules are not able to deal with Pubchem CID.
As per my experience -Pubchem CID was there for only molecules.
Thank You.

General Questions and Answers / Re: Requirement of anticancer drugs and cell lines(normal & cancer) in the data base
« on: May 18, 2025, 10:14 »Dear GJK
1. I can save the mol file format only as txt after opening from the drug bank,while giving the save as option .Just help me how to save in mol format.
Right click on the mol character part in the web and save it.
2.I lack the procedure to convert it to .xyz files using open babel.Kindly help me in sorting out this problem? so that I can start my research.
See. http://quantumwise.com/forum/index.php?topic=2543.msg11886#msg11886
and http://openbabel.org/wiki/Babel
3.Even though I tried for file conversion using open babel I could not save the output file.Kindly also specify the destination folder.
I think you can get a saved xyz file by procedure 2.

How to extract the biomarkers for cancer detection , Is it already there in the library of quantum atk ред Majorly those are cell lines or protine or DNA or aptamer or RNA! Pubchem CID is for small molecules not for those I have mentioned

General Questions and Answers / Re: This kind of device structure is Scientifically feasible for Quantum Atk?
« on: May 6, 2025, 11:17 »But but it's not necessary to simulate all 3 tubes together, a single one will be enough. One might use 3 in a real device for increase current density, but they operate individually.
So, this kind of device structure is more over feasible to operate in Quantum Atk? Like I refer previously. And according to you it will provide more current densities for ID VG. But what about the spatial region? Is it can be opted for a single spatial region for all 3 CNTS shown here? Could you please help me in this regard? by sharing a sample .py file where 3 NTs with a single spatial region throughout the device including dielectric. So that I can learn from that. Thank You.

General Questions and Answers / Offline version of the software
« on: April 30, 2025, 04:31 »
Good morning ,Hope you are doing well. This email is to ask a query regarding the usage of quantum atk software ,offline. Actually in hilly areas, the weather is very unpredictable. Mostly rainy throughout the year. That's why there is a chance of getting a power cut (Though we are having UPS) and network fluctuations (Major Network issues) very frequently. Currently we are using a licensed workstation by fetching the actual server. So, it must require a stable network(bridge between actual server and licensed PC for efficient task execution(NEGF Converged calculation), Which is practically obvious.
Main concern with respect to circumstances: To use the software offline(Licensed PC Workstation) to avoid network fluctuations and other stuff.
Kindly advise further, regarding the issues. Thank you.

General Questions and Answers / How to shift Dirac point of ambipolar chr. of ID VG for CNTFET
« on: April 25, 2025, 07:06 »
Dear sir,
Good morning, how to shift Dirac point of ambipolar chr. of ID VG for CNT. I wanted to shift it towards the negative x axis.
Actually, for the case, Working on 10nm cylindrical GAA CNT FET. Metal gate voltage =1.0V
Lanthanum oxide as a dielectric of 1.5nm
S/D=4nm
PIN Doping profile OR NIN Doping profile
Coming -Ambipolar behaviour
Wanted to optimize to perform better in terms of electrical parameters.
Also, how to make multiple Channels with 4X CNT for cylindrical GAA CNT FET
