Abstract

A device-quality GaAs monocrystalline films were fabricated on AlN polycrystalline films. The X-ray characterization reveals that the (001) preferential orientated AlN thick films with very low stress can be grown by DC reactive sputtering. The photothermal deflection spectroscopic measurements of the GaAs-on-AlN composite material show that a reasonably high thermal conductivity can be obtained. Hall measurements and I-V characteristics of Schottky diodes show that the epi-GaAs films on AlN thick films have similar electric properties of bulk materials.
