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…
Cavity-Enhanced Raman Scattering from 2D Hybrid Perovskites
Aditya Singh, Jason Lynch, Surendra B. Anantharaman +6
Two-dimensional (2D) hybrid organic-inorganic perovskites (HOIPs) are promising candidates for optoelectronic applications due to their efficient light emission properties, and str…
Free-standing bialkali photocathodes using atomically thin substrates
