Dr. Goldan is awarded his second NIH-R21 (NIBIB Trailblazer) grant for the feasibility study of a novel high-efficiency avalanche detector for high resolution x-ray imaging applications.
The proposed detector features a very thin layer of ultra-high efficiency Cadmium Selenide (CdSe), while coupled to a thicker multi-well avalanche amorphous selenium (a-Se) film, to serve as the photoelectric conversion layer for further enhancing the low-dose x-ray sensitivity (in addition to having avalanche gain inside a-Se). This project is inspired by the commercial success of solution-processed and highly tunable colloidal quantum dots (e.g., release of the first Quantum-Dot LED or QLED TV in 2015) for the formation of the CdSe layer. This project is in close collaboration with Professor Wei Zhao of Radiology who is also the Co-PI on this 3-year grant.
