MICROWAVE MEASUREMENT OF HALL MOBILITY: EXPERIMENTAL METHOD
Hall mobilities of germanium single crystals were measured at a frequency of 9000 Mc over the temperature range 30-300 deg K. A rectangular sample occupied the central part of a wall of a rectang-ular cavity, which was doubly degenerate in the TE/sub 101/ mode and in the TE/sub 011/ mode at a single resonance microwave frequency. The external magnetic field and the microwave field associated with one of the two modes gave rise to the other mode of oscillation. The theoretical analysis of Liu, Nishina, and Good was verified by measurements on an n-type sample having a room temperature resistivity of 0.40 ohm cm. The measured Hall mobility at microwave frequencies (with a size correction) was compared with the dc Hall mobility between 30 and 300 deg K. The agreement was excellent. (auth)
