Phonons Dispersion Relations In Chalcogenide Semiconductors:- Uzoma, Juliet E.
ABSRTACT
Phonon is a quantum of
vibrational energy and the phonons density of state gives the number of modes
per unit frequency per unit volume of real space. The entire set of all
possible phonons that are described by the phonon dispersion relation combine
in what is known as phonon density of state which determines the heat capacity
of a crystal. In a crystal each atom are coupled with the neighboring atoms by
spring constants. The equation of motion of atoms around thermal equilibrium
position was discussed in terms of several method, which include numerical
calculation on the eigenvalue problem (based on the mathematical) and the
translation operators in the quantum mechanics. MATLAB was used to run the
simulation. And in the simulation, the density of state and the dispersion relations
of the following semiconductors ( cadmium sulphide, cadmium telluride and
cadmium selenide) were calculated.
