Abstract :
In this work, Schottky barriers obtained from the SiGeB alloy on p-Si are demonstrated and proposed as photoemissive infrared photodetectors. The SiGeB alloy is obtained by PECVD at 300°C, the source gases used were SiH4, GeF4 and B2H6. The resulting barrier height when deposited onto p-Si is determined from I-V measurements and ranges from 0.7 to 0.38 eV. The main parameter in the barrier height control is the deposition pressure
