Uniaxial Strain Simulation not as specified
Closed | Responses: 2
I tried to some simple uniaxial strain simulation for bulk. The problem that I encountered is that even though I specified the initial and final strain, the strain value in the final results is not …
Strained nanowires behave oppositely to strain type
Open | Responses: 4
Device type: Cirular/Square silicon nanowire - channel dir: , conf dir: and channel dir: , conf dir: Dimensions: 2.5nm to 3.5nm Strain condition: longitudinal uniaxial tension/compression (-6% to …

What does confinement direction in UTB refer to?
Open | Responses: 2
Hi, In calculating the bandstructure for UTB films, the field "Confinement Direction" mentions the "Y" direction. However, the graphic shows "Y" along the width of the device. What does …
code crashes when 8nm triangular cross section nanowires are entered
Open | Responses: 3
code crashes when 8nm triangular cross section nanowires are entered crashes both in the electronic structure calculation as well as charge-selfconsistent calculation. Error message in the Output …
wishlist item: compare the initial and the final dispersion in selfconsistent calculation
wishlist item: compare the initial and the final dispersion in selfconsistent calculation. The way to do this is to have the initial dispersion on the left for negative k values and the new one for …
wishlist item: 2d cuts through potential and charge through high symmetry lines
wishlist item: 2d cuts through potential and charge through high symmetry lines for example in the ultra thin body have a cut in the 1D quantum well growth direction. In wires in horizontal and …
Bandstructure Lab, with the default values, is not generating any output figures! I was trying to assign a homework on how strain modifies the bandstructure, but could not get the simulations done.
atomic coordinates file should have the right file extension *.pdb so one can read it into a local visualizer right away
The ability to ownload a coorinate file is existing now. However the file comes back as a t *.txt file. It if ame back with the right extension, my local machine could immediately use the file. …
biaxial strain in bulk produces no results
Starting from scratch with a new simulation I am just turning on bi-axial strain in the bulk simulation mode and I get not simulation results.
Could k be expressed by kx ky kz?
I do not really know the meaning of "effective k" in the result figure.(the square root of kx ky kz?) This tool can show a table of k-E. Is this possible to show the "kx ky kz E" in the final result …
number of bands
Hi I simulated 6 bands, on the results it shows band no 1, 3,6 for Conduction band and like 1 and 3 for valence band. why are 2 and 4 missing Thanks Neel
what does self consistent calculation mean? when is oxide thickness included for Si NW calculation? Thanks for your excellent tool
Is it possible to simulate CdTe nanowire through the bandstructure lab? That will be tremendous help. Thanks in advance Neel.
simulation is slow for large diameters
I tried to run the simulator for fairly large InAs NW, with diameter ~5 to 20nm. Even with the number of conduction bands and k-points reduced, the simulation is still very slow, much slower than …
Strain in % or fraction
Does the 0.02 denote a fraction or percentage? from usual strain values,it looks like percentage but wanted to confirm
Highly non-spherical heavy hole bands for bulk GaAs??
I calculated the band structure of bulk GaAs. The effective masses for the heavy holes were given as:  0.376848  0.657788  0.839029 I thought the heavy hole bands of GaAs …
