Abstract

In this report, we describe thin 200nm thick GaN film formation technology on Si which allows microbolometer application. GaN layer with AlN buffer layer obtained by the MOCVD has TCR of about -0.64 %/°C and sheet resistance of ~2800 ohm/sq. Acquired GaN films were analyzed by XRD, SEM, Hall measurement, and etc. The successful growth of thin single crystalline or polycrystalline GaN film on Si can be a good semiconductor bolometric material. And the multi wavelength detecting systems with GaN based devices including UV detector, power devices, amplifier with GaN and AlGaN MOSFET, HEMT, and etc can be realized. We obtained thin(~200nm) crystalline GaN layer on Si(111) with AlN buffer layers with FWHM(full width at half maximum) of ~1800 arcsec. And its bolometric characteristic was analyzed.
