Abstract

Abstract: Hot-electron power loss via electron interaction with bulk longitudinal polar optical phonon in metal-oxide two dimensional nanostructures in the presence of zero and finite quantizing magnetic fields is investigated using electron temperature model. The dependence of power loss in two-dimensional nanostructures of transparent conducting oxides like ZnO, SnO2, CdO, In2 O3, Ga2 O3 is presented as a function of electron temperature and carrier density in zero and finite magnetic fields. Numerical calculations establish that external quantizing magnetic field enhances power loss of electrons. Further, electron power loss is proportional to the electron temperature and varies inversely with the carrier density. The electron magneto-power loss qualitatively differs from the oscillating dependence of the electron-phonon scattering on the quantizing magnetic field. Highlights: Electron power loss in two-dimensional nanostructures of Transparent Conducting Oxides (TCOs) in zero and quantizing magnetic fields. Perturbation technique is used for the case when electrons are scattered by bulk longitudinal polar optical phonons. Dependence of power loss on magnetic field, temperature and electron density has been studied.
