Exciton ground state fine structure and excited states landscape in layered halide perovskites from combined BSE simulations and symmetry analysis
Claudio Quarti, Giacomo Giorgi, Claudine Katan +2
Layered halide perovskites are solution-processed natural heterostructures where quantum and dielectric confinement effects down to the nanoscale strongly influence the optical pro…
Deterministic synthesis of phase pure 2D perovskites via progressive transformation of layer thickness
Jin Hou, Wenbin Li, Hao Zhang +5
Two-dimensional (2D) halide perovskites have emerged as semiconductor platforms for realizing efficient and durable optoelectronic devices. However, the reproducible synthesis of 2…
Direct visualization of ultrafast lattice ordering triggered by an electron-hole plasma in 2D perovskites
Hao Zhang, Wenbin Li, Joseph Essman +18
Direct visualization of ultrafast coupling between charge carriers and lattice degrees of freedom in photo-excited semiconductors has remained a long-standing challenge and is crit…
Direct evidence of weakly dispersed and strongly anharmonic optical phonons in hybrid perovskites
A. C. Ferreira, S. Paofai, A. Létoublon +8
Hybrid organolead perovskites (HOP) have started to establish themselves in the field of photovoltaics, mainly due to their great optoelectronic properties and steadily improving s…
From latent ferroelectricity to hyperferroelectricity in alkali lead halide perovskites
Guido Roma, Arthur Marronnier, Jacky Even
Using first principles calculations we show that several alkali lead halides potentially present collective ferroelectric polarization. This should occur at least at the nanoscale;…
Band-edge Exciton Fine Structure and Exciton Recombination Dynamics in Single crystals of Layered Hybrid Perovskites
Hong-Hua Fang, Jie Yang, Sampson Adjokatse +6
Two-dimensional (2D) perovskite materials have recently re-attracted intense research interest for applications in photovoltaics and optoelectronics. As a consequence of the dielec…
