Calculate ne, nh and - ec for n-type lnSb at 300K, assuming nd + = 4.6

Calculate ne, nh and μ - ec for n-type lnSb at 300K, assuming nd + = 4.6 x 10cm–3 = nc. Because of the high ratio nv/nc and the narrow energy gap, the hole concentration is not negligible under these conditions, nor ms the non-degenerate approximation nc << nc applicable. Use the generalized mass action law (39). Solve the transcendental equation for ne by iteration or graphically.
