Abstract
We examine electrons bound in quantum-mechanical states in the surface region of a cylindrically curved surface. As predicted by Prange, the energy-level scheme for such states is formally identical with that of a flat-surface sample, except for the replacement of magnetic field by an effective field , where and are the cyclotron and surface-curvature radii, respectively. The predicted field shift of the microwave impedance-oscillation spectrum of a (100)-plane Cu sample in weak magnetic fields has been observed and measured; this has allowed us to determine both the curvature radius and the Fermi velocity at the [100] point of the Cu Fermi surface. We find and cm/sec.
