InSb semiconductor-metal hybrid structure (SMH) as a magnetic sensor prepared by flash evaporation

n-type indium antimonide-Au van der Pauw (vdP) shape hybrid macro-structure were successfully fabricated on glass substrates by flash evaporation technique. The elemental composition of the prepared films was confirmed by energy dispersive X-ray spectroscopy microanalysis (EDX). The morphologies and crystal structures of the films were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD) respectively. The magnetoresistance of the prepared hybrid structure was measured at room temperature and 100mA current and a variable magnetic field (0-8kG). The effect of sensor geometry on magnetoresistance was studied.
