Pulse-Burst Excitation Reveals Time-Dose Reciprocity Breakdown in Mixed-Halide Perovskites
Alexandr Marunchenko, Shivam Singh, Daniel Lizotte +3
Time-dose reciprocity, commonly associated with the Bunsen-Roscoe law, states that the response of a photosensitive system depends only on the total exposure dose, regardless of ho…
Unraveling the Roles of Shallow, Deep and Auger Trapping in Charge Carrier Recombination in Triple-Cation Perovskites
Jitendra Kumar, Thomas Kirchartz, Alexandr Marunchenko +7
Understanding charge-carrier recombination in metal halide perovskites is essential for accurately identifying the factors limiting solar cell efficiency, yet it remains challengin…
Non-epitaxial perovskite polariton laser diode operating under direct current
Anatoly P. Pushkarev, Daria Khmelevskaia, Ivan A. Matchenya +11
Reaching lasing in electrically pumped microdevices based on solution-processed semiconductors poses a major scientific and technological challenge. Halide perovskites offer a prom…
Hidden photoexcitations probed by multi-pulse photoluminescence
Alexandr Marunchenko, Jitendra Kumar, Dmitry Tatarinov +3
Time-resolved photoluminescence is a validated method for tracking the photoexcited carrier dynamics in luminescent materials. This technique probes the photoluminescence decays up…
Extreme electron-photon interaction in perovskite glass
S. S. Kharintsev, E. I. Battalova, I. A. Matchenya +2
The interaction of light with solids can be dramatically enhanced owing to electron-photon momentum matching. This mechanism is driven by either quantum confinement or long-range s…
