[Wien] Temperature

[Fecher, Gerhard]

This is a repeated question that is not related to Wien2k but can be easily answered by reading a good textbook on solid state physics

DEEP THOUGHT in D. Adams; Hitchhikers Guide to the Galaxy:
"I think the problem, to be quite honest with you,
is that you have never actually known what the question is."

At 0 K a material may be a metal or semiconductor (or insulator). The conduction band represents the band of empty states at 0K which are the states which will be filled with electrons at high temperatures.
Practically there is no tangible difference between 0K and room temperature (300K), therefore a material if it is insulator at 0K will still insulator because as you said 2 meV is insufficient to cause transition from band to conduction band.
At high temperatures (around 1000 K) we feel a change in electronic properties.
