Project Description:

This project intends to explore SiGeSn film grown on Si substrate and their integration into devices for infrared light detection applications. As automobile advances, there are increasing needs to the incorporation of various detectors into the vehicles. Especially in autonomous vehicles, LiDARs are used to detect objects on the road, as a complementary detection technique to radar and image sensors. So far LiDARs use infrared laser as source and Si as detector materials, which limits its wavelength used for IR detection. This project will develop film growth and device fabrication processes for such detector on Si substrate, through collaboration with industrial partners.
