| Abstract: | The optimized system
parameters of polar semiconductor quantum wells have been calculated to get
desired high frequency response characterized by 3dB cut-off frequency at which
the ac mobility drops to 0.707 of its
low frequency value. The ac mobility
of two-dimensional hot electrons in square quantum wells of GaAs and (In, Ga)As
are computed numerically using heated drifted Fermi-Dirac distribution function
and prevalent scattering mechanisms. Genetic algorithm has been employed to get
the optimized system parameters for getting the desired high-frequency, small
power consuming and low dimensional devices, thereby saving significantly the
search time for the technologists involved in the fabrication of such devices. |
