Carrier relaxation and exciton dynamics in chemical-vapor-deposited two-dimensional hybrid halide perovskites
Dallar Babaian, Daniel Hill, Ping Yu, S. Guha
Abstract
Transient absorption spectroscopy from chemical vapor deposited 2D perovskites shows differences in carrier dynamics depending on the organic cations. The decay reveals a strong contribution from the Auger recombination process at early times.
