Title: Single crystal diamond for infrared sensing applications

The synthesis of new materials for thermal infrared (IR) detection has been an intensive research area in recent years. Among new semiconductor materials, synthetic diamond has the ability to function even under very high temperature and high radiation conditions. In the present work, diamond Schottky diodes with boron concentrations in the range of 10{sup 14 }< B < 10{sup 17 }cm{sup −3} are presented as candidates for IR thermal sensors with an excellent temperature coefficient of resistance (−8.42%/K) and very low noise levels around 6.6 × 10{sup −15} V{sup 2}/Hz. This enables huge performance enhancements for a wide variety of systems, e.g., automotive and space applications.
