General Questions and Answers / Device calculation for collinear electrodes

« on: January 27, 2021, 06:02 »

Dear Sir/Madam,

I want to do device simulation for concentric tubes. Where, my innermost and the outermost tubes act as electrodes. But, I have not been able to carry out the same as for a device simulation, the two ends are automatically considered as electrodes depending upon the size defined by the user.

Hence, could you please help me in this regard.

Thank You.

Dear Admin,

I am using free Academic license in my personal computer where i have been trying to view the plots of various simulations carried out in the full license version of Quatumwise ATK at our Institute (IIEST, Shibpur). But, for some reasons I am not being able to view the DOS 2D plots.

I have tried to reinstall the software again and also by re-downloading the software and using it. Still the problem persists. Please help in this regard as the error message also says to report for the error to Quantumwise.

I am attaching the error messages as .pdf files.
