High Performance Temperature Sensors using SC-CVD Diamond Schottky Diodes

• The synthesis of new materials for thermal IR detection has been an intensive research area during the recent years. Among the new materials, diamond has the ability to function under high temperature, high power, and high radiation conditions, which enables large performance enhancements to a wide variety of systems and applications, e.g. electric vehicles, space exploration and nuclear energy reactors. In this study, diamond Schottky diodes (with boron concentrations in the range 1×1015 - 3×1016 cm-3) are presented as candidates for IR sensors with an excellent temperature coefficient of resistance (-16 %/K) and noise levels around 1.8×10-14 (V2/Hz).
