Abstract: The conversion efficiency of solar energy in semiconductors is fundamentally limited by ultrafast hot-carrier relaxation processes, and slowing down these processes is critical for improved energy harvesting. Here we report formamidinium tin iodide (FASnI3) nanocrystals… read more here.

DOI: 10.3938/jkps.73.314
Abstract: We have performed time-resolved photoluminescence of dilute GaAs/AlGaAs quantum rings for increasing excitation and temperature. Although a large distance between quantum rings (200 ± 50 nm) prevents a ring-to-ring carrier transport, a decay time difference… read more here.
