Cyclotron resonance in n-type ZnO

Abstract The magnetic field dependence and the temperature dependence of the cyclotron resonance were investigated in n-type ZnO. The observed resonance was assigned as not a conduction electron cyclotron resonance but trapped electron cyclotron resonance from the magnetic field dependence of the resonant energy. The effective mass and the electron–phonon coupling constant were calculated as m * =0.23 m 0 and α =1.2 from the obtained polaron mass, m * pol =0.29 m 0 .
