摘要: A method and apparatus for the contactless, non-destructive measurement of Hall coefficient resistivity a piezoelectric semiconductor sample. The material to be tested is formed in disk which supported at its edge by holder. disc free vibrate. Two pairs electrodes, placed above below sample, excite sample into beyond resonance. Then magnetic field applied again driven Comparison between performance before after application yields data from can determined.
