Abstract:
In this research a quantum expressions for absorption coefficient,
effective mass and relaxation time are obtained by modifying
Schrödinger equation solutions, with the aid of Maxwell's and Boltzmann
statistical distribution.
These expressions are verified by performing experiments from which
empirical relations between the absorption coefficient and concentration
of P and Fe beside the magnetic field are obtained. These expressions are
in conformity with the theoretical ones.
The values of the relaxation time, effective mass, energy gap and
mobility are also obtained from experiments. These values are
comparable with the standard values (
