what is the maximum ramp energy usable in DEMONs?
04 Dec 2009
There is probably a limit inside the program, but I don’t know what it is. On the other hand, I’ve never used more than 0.3eV. Demons uses a simple, nonparabolic E(k). The bandstructure limited velocity for most semiconductors is about 1e8 cm/s, Higher ramp energies will produce higher velocities – you should be sure that you don’t get velocities above 1e8 cm/s.
