1. An electron near the top of the valence band in a semiconductor has energy E = -10-38|k|² where E is in Joules and k is in m-1. An electron is removed from a state k = 4 x 108 m-1 ^x, where ^x is the unit vector in the x-direction. For a hole, calculate the following: (ħ = 1.054×10-34 J·s, 1 J =6.24 x 1018 eV) (a) the effective mass (unit: kg) (b) the energy (unit: eV) (c) the momentum (unit: kg-m/s) (d) the velocity (unit: m/s)
