液氦上非简并2DES中新的辐射感生磁电阻振荡

Novel Radiation-induced Magnetoresistance Oscillations in a Nondegenerate 2DES on Liquid Helium

Denis Konstantinov, Kimitoshi Kono

摘要:

本文报道了在束缚于液氦表面的非简并二维电子中,由子带间共振吸收引起的新型磁阻振荡的观测结果。的振荡是周期性的1/B和起源于散射介导的跃迁的激发电子到朗道状态的第一子带。振荡的结构受到朗道能级碰撞展宽和多电子效应的影响。

英文摘要:

We report the observation of novel magnetoresistance oscillations induced by the resonant inter-subband absorption in nondegenerate 2D electrons bound to the surface of liquid helium. The oscillations are periodic in 1/B and originate from the scattering-mediated transitions of the excited electrons into the Landau states of the first subband. The structure of the oscillations is affected by the collision broadening of the Landau levels and by many-electron effects.
