Jungwirt, G. and Kropf, R. and Prettl, Wilhelm (1991) Nonlinear fir magneto-photoconductivity on quasi-bound Coulomb states of light holes in high purity p-Ge. International Journal of Infrared and Millimeter Waves 12 (7), pp. 729-744.
The far-infrared magneto-photoconductivity due to optical transitions from the acceptor ground state into quasi-bound Coulomb states in p-Ge has been investigated at low temperatures as a function of intensity applying a high-power cw molecular laser. For intensities above about 1 mW/cm2 the photoconductive signal shows a square root dependence on intensity, which is attributed to nonlinear free ...
