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…
Anharmonic lattice dynamics via the special displacement method
Marios Zacharias, George Volonakis, Feliciano Giustino +1
On the basis of the self-consistent phonon theory and the special displacement method, we develop an approach for the treatment of anharmonicity in solids. We show that this approa…
Fine Structure of Excitons in Vacancy Ordered Halide Double Perovskites
Bruno Cucco, Claudine Katan, Jacky Even +2
Vacancy ordered halide double perovskites (VODP) have been widely explored throughout the past few years as promising lead-free alternatives for optoelectronic applications. Yet, t…
Antiphase boundaries in III-V semiconductors: Atomic configurations, band structures and Fermi levels
L. Chen, L. Pedesseau, Y. Léger +3
Here, we comprehensively investigate the atomic structures and electronic properties of different antiphase boundaries in III-V semiconductors with different orientations and stoic…
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…
