title: Development of multi-frequency ESR/EDMR system using a rectangular cavity equipped with waveguide window.
abstract: A straightforward method for a variable frequency electron spin resonance/electrically detected magnetic resonance (ESR/EDMR) spectroscopy using a C-band microwave cavity equipped with waveguide windows is presented. The method enables us to perform quasi-continuous multiple resonance frequency (MF-ESR/EDMR) experiments for electronic devices. The C-band microwave circuitry was selected because of larger available sample volume than that for conventional X-band one. All the measurements were performed using a combined sample of 2,2-diphenyl-1-picrylhydrazyl/ pn-junction Si diode. The present simple MF-ESR/EDMR method will be useful for the characterization of electronic and optoelectronic devices.
