Özet

In this study, the binding energy (E_B) and optical properties, absorption coefficient (AC) and refractive index change (RIC) of a GaAs cubic quantum dot are studied for different pressure and temperature values. Numerical calculations are done by using variational method. The results present that E_B, the linear and nonlinear optical properties are sensitively dependent on the pressure, temperature and quantum dot size. Also, the results indicate that it is possible to modulate the resonant peaks position and magnitude of the AC and RIC with pressure and temperature
