At room temperature, an intrinsic alas has 4x minima along < 100> directions, and the following data are available: electronics mass for î valley and x valley are 0.15 m0 and 0.76 m0. the hole mass is 0.76 m0. at what temperature the number of electrons in the î minima and x minima will be equal if the energy separation between them is 0.40 ev? the band gap for alas is 2.23 ev.
