摘要
Oscillations reported by Dunifer et al. in microwave transmission through thin K layers are found to be periodic in 1/H. The oscillations arise from conduction-electron Landau levels passing through a small cylindrical sheet of the Fermi surface. This cylinder had been envisioned theoretically after incorporating both charge-density-wave and crystalline potentials in Schrodinger's equation. The cylinder's cross-sectional area is found to be pi-k(F)2/69, in agreement with the area inferred from the perpendicular-field cyclotron resonance, discovered by Grimes in the surface impedance.
