Confinement Effective mass
Closed | Responses: 1
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 …
Abnormal Termination of DGMOS UTB Self-Consistent Simulation
Closed | Responses: 0
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 …
2% biaxial strain Ge, promen at the Gamma point
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 …
L point on bulk central bands and bulk (all) band structure plots appears truncated
When simulating the bulk band structure for GaAs and Si (I haven't tried others), I noticed that the L point appears to be truncated on the plots. If I use an earlier version of the tool (1.x) I see …
The results for strained Si nanowire are different with the other literature
Hello, The obtained results for strained silicon nanowire are different with other literature. The energy difference between the minimum of light and heavy bands should be decreased in presence …
Self Consistent for Ge DGMOS
I am currently trying to simulate the Band structure for a Ge DGMOS (with thickness 4nm) using self consistent calculation at a particular Bias Voltage. However the simulator is unable to complete …
what kind of new research can be done by this tool? any exercise? in details..plz
can we simulate the band structure of graphene?
Why do I not see option for choosing different crystal directions for bulk materials?
Does simulation assume 300K?
Is it possible to calculate band structure at different temp?
No output for self-consistent calculation
Hi, I ran the tool for self-consistent calculation but I didn't obtain any result. It seems the tool does not work for this type of job. However, for non-self-consistent it works correctly. I …
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* …
Strain Tight-Binding model
I would like to know how this tool accounts the strain in TB Hamiltonian. Does it alter both the on-site and off diagonals elements? I would truly appreciate if you could help me out.
Bulk Si eff. mass vs. biaxial Strain
Closed | Responses: 2
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 …
Hi there, It seems that the tool is not working...I was able to get some output couple of hours back but now it shows only a bunch of log files everytime I simulate anything. Tried restarting + …
why the duplicated charge distriboution under low bias gate is not same as the paper?
I'm trying to duplicate " Band structure effect in silicon Nanowire electron transport" paper results for N-MOS, but I couldn't obtain the same result. In the case of Vg= 0, the charge dispersion …
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
Time for running on steele is far too long compared with nanohub.
How to get visual results
Open | Responses: 1
I run with default parameters and get no visual results for bandstructure.
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 …
