General Questions and Answers / Re: calculation of gate oxide capacitance

« on: October 8, 2025, 06:26 »

I suppose you are mainly looking at how the electron density changes with bias, so you can just subtract the zero-bias electron density and that's your bias-induced charge transfer.

General Questions and Answers / Re: How to get carrier density in a device?

« on: September 25, 2025, 08:32 »

Especially when processing an I-V curve calculation with bias.

Also, can we Do the analysis of electric field , Current density , EF, Mobility variations for FET Device ?

If then how, Like what will be the efficient / suitable calculator and analysis block

Thanks

Dear sir,

Good morning, Hope this msg finds you well. PFA the snap shot for linearity analysis. How to perform this using quantum atk
Thank you.

If I provide the .opju ( Origin file ) or CSV file of ID-VGS Data of each devices(5 devices) . Can I get those analysis or someone can guide me once.  Then I can do the rest. Thank you.

Yes, use IVCharacteristics, it works fine without gate too.

Not sure about IVCurve, is your problem that you can't read and plot old files?

Facing the same problem. Kindly advise.

General Questions and Answers / Re: When GUI crashes it locks the hdf5 files

« on: September 2, 2025, 07:24 »

Ok, but it's more of a operating system thing, than anything we can control in our code

As I am not aware whether the issue I have faced is similar to this or not . But still I would like to request you to guide me regarding this. For my case- I have successfully executed the hdf5 file based on convergence IV simulation for 10hrs. But after that I can not visualize the HDF5 file from " Data" Section of the software.  I have also tried to close and reopen the software and also I have copied the file in to the output folder as well.  Please help me to retrieve the IV Data  atleast within excel file. Thank you.

Hi,

Try closing and reopening QuantumATK. Also, make sure you have selected right folder under project icon (Top left)

Yes , I have done that but the issue persists.

General Questions and Answers / Executed IV HDF5 File is not showing at "Data" Section even saved at the folder

« on: August 28, 2025, 06:00 »

Dear experts,


Good morning, Executed IV HDF5 File is not showing at "Data" Section even saved at the desired folder. This is happening when I am using the updated version of the software. The simulation and execution itself has been done at the updated latest software.
I have tried that also , By moving the file from one location to another location.
