Abstract

Sascha Feldmann1

Harvard University1
Halide perovskites are fascinating semiconductors for light-emitting applications. Compared to conventional inorganic covalent semiconductors like silicon or GaAs, perovskites are structurally soft and often more disordered. Understanding the consequences of this remains a key challenge for commercialization.<br/>Here I will present our recent mechanistic insights from spectroscopy on the role of composition, doping and dimensionality to control light emission through localization in these materials, including the introduction of a new method of doping halide perovskites at room temperature and its impact on excitation dynamics.
