Abstract
There are many studies on low-dimensional semiconductors, including quantum wells. Conductivity tensor is one of the key concepts in materials research. This work studies the dependence of the conductivity tensor on electromagnetic waves and laser fields in a quantum well with infinite potential in the case of electrons - optical phonon scattering. Results are obtained using the quantum kinetic equation for electrons in a quantum well, the particle system is placed in an electromagnetic wave field and a laser field, from solving the quantum kinetic equation yields conductivity tensor expressions.This work also only considers the case of electron scattering - optical phonon and with quantum well there can be infinite potential. The conductivity tensor expression shows its dependence on the electromagnetic wave frequency, laser field frequency, laser field amplitude, and other parameters that characterize the quantum well.A graph of the dependence of the conductivity tensor on electromagnetic wave frequency, laser field frequency, and laser field amplitude will be plotted and examined. The semiconductor investigated here is the GaAs/GaAsAl quantum well.
