Methylammonium-Based Quasi-Two-Dimensional Perovskite Single Crystals for Highly Sensitive X‑ray Detection and Imaging [PDF]
, 2023 The strategy of introducing large organic cations into three-dimensional perovskites could reduce the dimensionality of perovskites to form quasi-two-dimensional (quasi-2D) perovskites, resulting in increased stability and reduced detection limits due to

A new potential for methylammonium lead iodide. [PDF]
, 2017 We present a new set of interatomic potentials for modelling methylammonium lead iodide. The potential model uses existing potentials for lead iodide and methylammonium, and new functions are fitted to enable these pre-existing potentials to be used ...

Tetrabutylammonium cations for moisture-resistant and semitransparent perovskite solar cells [PDF]
, 2017 Tetra-butylammonium cations have been partially substituted for methylammonium cations in perovskite thin films. The stability of devices stored under ambient conditions was enhanced by the presence of TBA and cells with high mol% TBA were found to have ...
