Femtosecond and highly sensitive GaAs metal?semiconductor?metal photodetectors grown on aluminum mirrors/pseudo-substrates

Original language description

Ultrafast metal-semiconductor-metal photodetectors on GaAs grown on aluminum mirrors/pseudo-substrates were fabricated and tested. Surface characterization measurements reveal the good quality of the surface morphology, while X-ray diffraction measurements show several crystallographic orientations of the GaAs layer. The material exhibits a 50 fs carrier lifetime due to growth-induced defects. The response of the photodetectors shows a full width at half maximum of 300 fs. These results demonstrate thatthe growth of GaAs layers on lattice-mismatched metallic substrates with a high thermal conductivity is a promising approach for low-cost and large-area fabrication of electronic and ultrafast photonic devices that require a highly effective thermal drain.
