An echo of an exciting light pulse in quantum wells
I. G. Lang, L. I. Korovin, D. A. Contreras-Solorio +1
The non-sinusoidal character oscillations appear in the transmitted, reflected and absorbed light fluxes when light pulses irradiate a semiconductor quantum well (QW), containing a…
Reflection and absorption of QWs irradiated by light pulses in a strong magnetic field
I. G. Lang L. I. Korovin, D. A. Contreras-Solorio, S. T. Pavlov
It has been shown that the non-sinusoidal character oscillations appear in the transmitted, reflected and absorbed light fluxes when light pulses irradiate a semiconductor quantum…
Magnetopolaron effects in light reflection and absorption of a three-level system in a QW
I. G. Lang, L. I. Korovin, D. A. Contreras-Solorio +1
The light absorption {\cal A} and reflection{\calR} coefficients for a three-level system in a quantum well (QW) in a strong magnetic field {\bf H}, directed perpendicularly to the…
Polar optical phonons at interfaces: influence of the concentration of Al
A. E. Chubykalo, D. A. Contreras-Solorio, M. E. Mora-Ramos
We study long-wavelength polar optical modes at semiconductor interfaces of GaAs|Al_{(x)}Ga_{(1-x)}As and take into account influence of the Al concentration. We have considered tw…
