Heating of Electrons in Pure Ge in a Quantum Magnetic Field Upon the Thermal Excitation of Charge Carriers

Abstract: The results of an experimental investigation into heating carriers by an electric field (E) in pure Ge in a quantum magnetic field (H) at (E ⊥ H) at low temperatures, T = 4.2, 1.8 K, under thermal excitation conditions are considered. It is shown that the average carrier lifetime is affected by the dependence of the thermal-ionization coefficient on E and H. These results agree qualitatively with the theory of cascade carrier capture at isolated centers in crossed electric and magnetic fields. © 2020, Pleiades Publishing, Ltd.
