Web(1) Find the bandgap of Diamond; (2) Is Diamond a direct semiconductor or indirect semiconductor? (3) Write the equation you would use to calculate effective mass from E-k diagram; (4) There are two types of holes (denoted as Hole A and Hole B) at the valence band maximum. Which one has smaller effective mass? WebJun 7, 2024 · Semiconductors, as we noted above, are somewhat arbitrarily defined as insulators with band gap energy < 3.0 eV (~290 kJ/mol). This cutoff is chosen because, as we will see, the conductivity of undoped semiconductors drops off exponentially with the band gap energy and at 3.0 eV it is very low.
