Disorder origin of Raman scattering in perovskite single crystals

Physical Review Materials, 2023
The anharmonic lattice dynamics of oxide and halide perovskites play a crucial role in their mechanical and optical properties. Raman spectroscopy is one of the key methods used to study these structural dynamics. However, despite decades of research, existing interpretations cannot explain the temperature dependence of the observed Raman spectra.

Microfluidic‐Assisted Growth of Perovskite Single Crystals for Photodetectors

Advanced Materials Technologies, 2023
AbstractThe organometal halide perovskites (OMHP) are promising candidates for fast, sensitive, and large area photodetectors. In the last decade, several techniques have been developed with complementary advantages. Film devices are thin and can be scaled to large area, but have a large number of grain‐boundaries related defects.

Directed assembly of layered perovskite heterostructures as single crystals

Nature, 2021
The precise stacking of different two-dimensional (2D) structures such as graphene and MoS2 has reinvigorated the field of 2D materials, revealing exotic phenomena at their interfaces1,2. These unique interfaces are typically constructed using mechanical or deposition-based methods to build a heterostructure one monolayer at a time2,3.
