ECE 290 Seminar: “From Materials Science to Detector Development: Engineering Semiconductors for Photon and X-ray Detection”
Presented by: Katie Hellier, Postdoctoral Scholar @ University of California, Santa Cruz
Description: “Semiconductor detectors are used in a wide range of applications, from medical imaging to high-energy physics, with different applications requiring different material properties and performance characteristics. Amorphous selenium is a well-established photoconductor for X-ray imaging, with properties that make it promising for a broader range of photon detection applications.
In this talk, we will discuss our group’s research on developing amorphous selenium detectors for direct and indirect X-ray conversion, optical photodetection, and particle detection. We will explore how semiconductor alloying and device architecture can be used to improve detector performance and expand potential applications, as well as the challenges involved in materials fabrication, characterization, and performance evaluation.”
