In intrinsic semiconductor, electrons jump into conduction band, a hole is left in valence band.
My question is the above statement correct? I though the hole is something we imagine, how to say the hole is in the valence band?
If I said an electron is in valence band, is that implying that the energy level of that electron is lower compared to the electron in fermi level? Am I correct? or it has any other meaning?
Thank you.
