“…The other derivative electronic properties such as effective mass ( m *) and thermal velocity ( V th ) for electron and hole, the conduction and valence band density of states, i.e., N C and N V are calculated as [ 46 ] Where h , ℏ, K B , m e, and m h are Planck constant, reduced Planck constant, Boltzmann constant, the mass of electron, and mass of hole, respectively.…”
