โœฆ Synopsis

Effects of periodic curvature on the electrical resistivity of corrugated semiconductor films are theoretically considered. The presence of a curvature-induced potential affects the motion of electrons confined to the thin curved film, resulting in a significant resistivity enhancement at specific values of two geometric parameters: the amplitude and period of the surface corrugation. The maximal values of the two parameters in order to observe the corrugation-induced resistivity enhancement in actual experiments are quantified by employing existing material constants.

High precision measurements of the electrical resistivity (p) of TiNb and TiV alloys in magnetic fields up to 23T revealed a slight enhancement of the resistivity (Ap) below T = 5-32 K. The temperature dependence and the magnetic field dependence of Ap depend on the m gnitude of the % resistivity p
