Two semiconductors are identical except that one has a band gap of 1.2 ev, while the other has a band gap of 1.1 ev. the room temperature (t = 300 k) intrinsic carrier density of the 1.1 ev material is ni1(300k) = 1.0×1019 m−3 and that of the 1.2 ev material is ni2(300k).1)calculate the ratio of intrinsic carrier densities for the two materials at room temperature. ni2/ni1=7.56×10−21
