Atomic-level description of thermal fluctuations in inorganic lead halide perovskites
Oliviero Cannelli, Julia Wiktor, Nicola Colonna +10
The potential of lead-halide perovskites for realistic applications is currently hindered by their limited long-term stability under functional activation. While the role of lattic…
Quantifying Photoinduced Polaronic Distortions in Inorganic Lead Halide Perovskites Nanocrystals
Oliviero Cannelli, Nicola Colonna, Michele Puppin +16
The development of next generation perovskite-based optoelectronic devices relies critically on the understanding of the interaction between charge carriers and the polar lattice i…
Giant exciton Mott density in anatase TiO2
Edoardo Baldini, Tania Palmieri, Adriel Dominguez +2
Elucidating the carrier density at which strongly bound excitons dissociate into a plasma of uncorrelated electron-hole pairs is a central topic in the many-body physics of semicon…
Strain Wave Pathway to Semiconductor-to-Metal Transition revealed by time resolved X-ray powder diffraction
C. Mariette, M. Lorenc, H. Cailleau +42
Thanks to the remarkable developments of ultrafast science, one of today's challenges is to modify material state by controlling with a light pulse the coherent motions that connec…
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…
Exciton Control in a Room-Temperature Bulk Semiconductor with Coherent Strain Pulses
Edoardo Baldini, Adriel Dominguez, Tania Palmieri +4
The coherent manipulation of excitons in bulk semiconductors via the lattice degrees of freedom is key to the development of acousto-optic and acousto-excitonic devices. Wide-bandg…
