2% biaxial strain Ge, promen at the Gamma point
Closed | Responses: 0
Dear all, When I simulate the bandstructure of Ge with high strain (2%), I get a discontinuity at the Gamma point, and therefore the effective masses are not correctly calculated. Can you improve …

Abnormal Termination of DGMOS UTB Self-Consistent Simulation
When running an Ultra-thin body MOSFET simulation with the job type set to "Calculate the UTB band-structure self consistently [for 1 gate bias point]," and all other simulation parameters set to the …

atomic coordinates file should have the right file extension *.pdb so one can read it into a local visualizer right away
Open | Responses: 2
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
Open | Responses: 3
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.
bulk bandstructure: k-axis scale
It seems that the bulk bandstructure shows E-k along L->Gamma->X->UK->Gamma. If so, the k-scale does not seem to be correct. The distance between Gamma and X appear to be correct (2pi/a0), but the …
Bulk Si eff. mass vs. biaxial Strain
Hello there, I was simulating Strain sweep on Bulk Si. I applied biaxial strain from -0.015 to 0.015 in  direction. I am interested in hole effective mass change as a function of strain. For …
Can not see any results in the drop down menu.
Hello, When I simulate the tool e.g. UTB default simulation, after completion of the simulation I can not find any outputs .In the results drop down menu input deck, backend code log, times …
can we simulate the band structure of graphene?
code crashes when 8nm triangular cross section nanowires are entered
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 …
Confinement Effective mass
Dear Admins, I am interested in calculating the effective mass along the confinement direction for nanowire geometries. Can this be done using Bandstrlab or is there another tool for it? Thanks and …
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 …
differences between sp3s* and sp3d5s* models
In this version of bandstrlab, the sp3s* model is not implemented (there is only one model, i.e. the sp3d5s*). It would be interesting to have that model to compare the differences between the sp3s* …
Does a positive value of epsilon correspond to tensile strain?
Does simulation assume 300K?
Is it possible to calculate band structure at different temp?
Doping the Nanowire
Hello, I'm beginner at using this tool. would you please let me know that we can dope the nanowire (channel) itself? thanks
