Organic-inorganic hybrid perovskites exhibiting exceptional photovoltaic and optoelectronic properties are of fundamental practical interest, owing to their tunability low manufacturing cost. For applications, however, challenges such as material instability the photocurrent hysteresis occurring in perovskite solar cells under light exposure need be understood addressed. While extensive investigations have suggested that ion migration is a plausible origin these detrimental effects, detailed...
Nanoscale strain control of exciton funneling is an increasingly critical tool for the scalable production single photon emitters (SPEs) in two-dimensional materials. However, conventional far-field optical microscopies remain constrained spatial resolution by diffraction limit and thus can provide only a limited description nanoscale localization SPEs. Here, we quantify effects heterogeneous on energy brightness GaSe SPEs nanopillars with correlative cathodoluminescence, photoluminescence,...
