4H-SiC PIN diode as high temperature multifunction sensor

• An in-house fabricated 4H-SiC PIN diode that has both optical sensing and temperature sensing functions from room temperature (RT) to 550 ºC is presented. The two sensing functions can be simply converted from one to the other by switching the bias voltage on the diode. The optical responsivity of the diode at 365 nm is 31.8 mA/W at 550 ºC. The temperature sensitivity of the diode is 2.7 mV/ºC at the forward current of 1 μA.
