摘要：

We examine the high-frequency conductivity and cyclotron resonance of electrons in a space-charge layer on a Ge (111) surface. It is shown from the frequency dependence of the infrared absorption that the surface carriers are localized or at least strongly perturbed for densities Ns1×1012 cm-2. The cyclotron resonance shows a shift of the resonance to low magnetic field at such densities. Only above ∼2 × 1012 cm-2 is the free-electron cyclotron mass observed. © 1979 The American Physical Society.
