New Publication

A new Center for Integration of Modern Optoelectronic Materials on Demand (IMOD) team publication in Nano Letters led by the Ginger group at the University of Washington reports silane-coated FAPbBr₃ quantum dots as promising single-photon emitters that rival state-of-the-art systems at room temperature while offering enhanced photostability. However, this advantage diminishes at cryogenic temperatures, where unexpected degradation pathways begin to dominate. By uncovering a trion-driven mechanism behind this behavior, the study provides key insights into the temperature-dependent limits of surface passivation strategies.
