Atreyo Mukherjee’s new paper titled “Monte Carlo Solution of High Electric Field Hole Transport Processes in Avalanche Amorphous Selenium” was published in ACS Omega. Amorphous selenium lacks the structural long-range order present in crystalline solids. However, the stark similarity in short-range order that exists across its allotropic forms, augmented with a shift to non-activated extended…Continue Reading February 2021

Our new paper titled “Ultra-low Dark Currents in Avalanche Amorphous Selenium Photodetectors using Solution-processed Quantum Dot Blocking Layer” was published in ACS Photonics. In this paper, we propose a true solid-state alternative to the vacuum photomultiplier tube using amorphous selenium as the bulk avalanche i-layer. To achieve reliable and repeatable impact ionization gain without irreversible…Continue Reading June 2020

Dr. Goldan has received a new NIH grant entitled “SWAD: Large-Area Photon Counting X-Ray Imager Using Amorphous Selenium”. In this NIH R01 grant, we proposed to develop a prototype hyperspectral photon counting imager using the field-Shaping multi-Well Avalanche Detector (SWAD) for high spatial resolution contrast-enhanced x-ray breast imaging. Given that the photosensor material is amorphous, the…Continue Reading July 2019
