Higher Harmonic Cyclotron Resonance of Holes near Electron-Hole Droplets in Germanium

抄録

The origin of pronounced third harmonic signals of heavy holes in germanium observed in optically detected cyclotron resonance experiments is discussed. It is shown that strong higher harmonic cyclotron acceleration is possible for holes through a nonuniform field due to an electric dipole moment induced by the microwave field on an electron-hole droplet.
