Oscillations in the photoconductivity of n-GaAs with monochromatic infrared illumination in a magnetic field
Zverev V. N., Shovkun D. V.
The curve of the photoconductivity of rc-GaAs versus the magnetic field during monochromatic infrared illumination reveals oscillations consisting of two series of extrema which are periodic along the inverse-field scale. One series of extrema stems from the nonmonotonic field dependence of the impurity magnetoabsorption coefficient, the other stems from a sharp step in the distribution function of nonequilibrium electrons.
