Kinetic modelling of carrier cooling in lead halide perovskite materials
Thomas R. Hopper, Ahhyun Jeong, Andrei Gorodetsky +6
The relaxation of high-energy "hot" carriers in semiconductors is known to involve the redistribution of energy between (i) hot and cold carriers and (ii) hot carriers and phonons.…
Memories in the Photoluminescence Intermittency of Single Cesium Lead Bromide Nanocrystals
Lei Hou, Chen Zhao, Xi Yuan +6
Single cesium lead bromide (CsPbBr3) nanocrystals show strong photoluminescence blinking, with on- and off- dwelling times following power-law distributions. We investigate the mem…
Evidence of large polarons in photoemission band mapping of the perovskite semiconductor CsPbBr
M. Puppin, S. Polishchuk, N. Colonna +16
Lead-halide perovskite (LHP) semiconductors are emergent optoelectronic materials with outstanding transport properties which are not yet fully understood. We find signatures of la…
High-resolution remote thermography using luminescent low-dimensional tin-halide perovskites
Sergii Yakunin, Bogdan M. Benin, Yevhen Shynkarenko +6
While metal-halide perovskites have recently revolutionized research in optoelectronics through a unique combination of performance and synthetic simplicity, their low-dimensional…
