Cyclotron resonance in n-type ZnO

The magnetic field dependence and the temperature dependence of the cyclotr on resonance were investigated in n-type ZnO. The observed resonance was as signed as not a conduction electron cyclotron resonance but trapped electro n cyclotron resonance from the magnetic field dependence of the resonant en ergy. The effective mass and the electron-phonon coupling constant were cal culated as m(*) = 0.23m(0) and alpha= 1.2 from the obtained polaron mass, m (pol)(*) = 0.29m(0). (C) 2001 Elsevier Science B.V.
