Abstract
A new effect of magnetic quantum oscillation of high electric field magnetoresistance due to the electron trapping with emission of multiple LO-phonons is reported together with the oscillation due to the Auger recombination. Oscillations were observed successfully in n−Hg 1- x Cd x Te ( x ≅ 0.2) in a wide temperature range 4.2–100 K, by the combination of a pulse technique and a second derivative method. Analysis shows that, in the moderate quality samples, recombination through deep trap center is dominant at low temperatures while Auger recombination is dominant at the higher temperatures.
