Dear sirs,
to make a Si nanowire, one can start with silicon from database then he can take it to bulk builder to make a bulk si. then we can take it to nanowire of custom builder. If he chooses the bandstructure from nanoscript writer, vnl will show the bandstructure of silicon nanowire.
But if he chooes only si from database to make nanowire in the custom builder without making it bulk, does the bandstructure show the correct result?
it can be also applied in GaAs or InP nanowire.
please let me know which one is correct one. And another thing, why only bulk silicon does not show the correct bandgap? it shows 2.3eV where i have change all parameter but it does not show correct result. Again it does not show band splitting in the valence band. I think i lag some theoretical aspects or the software has some technical trick? please let me know about it.
thanks.
