abstract = {In this study, ultrafast GaAs metal–semiconductor–metal
(MSM) photodetectors grown on aluminum
mirrors/pseudo-substrates were fabricated and tested.
Surface characterization measurements revealed the good
quality of the surface morphology, while x-ray diffraction
measurements showed several crystallographic orientations of
the GaAs layer. The material exhibited a 50 fs carrier
lifetime due to growth-induced defects. The response of the
photodetectors showed a full width at half maximum of 300
fs. These results demonstrate that the growth of GaAs layers
on lattice-mismatched metallic substrates with 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.},
