Acoustic-optical phonon up-conversion and hot-phonon bottleneck in lead-halide perovskites
The hot-phonon bottleneck effect in lead-halide perovskites (APbX(3)) prolongs the cooling period of hot charge carriers, an effect that could be used in the next-generation photovoltaics devices. Using ultrafast optical characterization and first-principle calculations, four kinds of lead-halide pe...
