Metal halide thermoelectrics: prediction of high-performance CsCu2I3
Jong Woong Park, Young-Kwang Jung, Aron Walsh
Thermoelectric devices can directly convert waste heat into electricity, which makes them an important clean energy technology. The underlying materials performance can be evaluate…
Inhomogeneous Defect Distribution in Mixed-Polytype Metal Halide Perovskites
Young Won Woo, Zhenzhu Li, Young-Kwang Jung +2
The competition between corner, edge and face-sharing octahedral networks is a cause of phase inhomogeneity in metal halide perovskite thin-films. Here we probe the charged iodine…
Bismuth-doping Alters Structural Phase Transitions in Methylammonium Lead Tribromide Single Crystals
Erin Jedlicka, Jian Wang, Joshua Mutch +8
We study the effects of bismuth doping on the crystal structure and phase transitions in single crystals of the perovskite semiconductor methylammonium lead tribromide, MAPbBr3. By…
Lattice compression increases the activation barrier for phase segregation in mixed-halide perovskites
Loreta A. Muscarella, Eline M. Hutter, Francesca Wittmann +7
The bandgap tunability of mixed-halide perovskites makes them promising candidates for light emitting diodes and tandem solar cells. However, illuminating mixed-halide perovskites…
Thermodynamic stabilization of mixed-halide perovskites against phase segregation
Eline M. Hutter, Loreta A. Muscarella, Francesca Wittmann +7
Mixing iodide and bromide in halide perovskite semiconductors is an effective strategy to tune their bandgap, therefore mixed-halide perovskites hold great promise for color-tunabl…
Local Strain Heterogeneity Influences the Optoelectronic Properties of Halide Perovskites
Timothy W. Jones, Anna Osherov, Mejd Alsari +18
Halide perovskites are promising semiconductors for inexpensive, high-performance optoelectronics. Despite a remarkable defect tolerance compared to conventional semiconductors, pe…
Perspective: Theory and simulation of hybrid halide perovskites
Lucy D. Whalley, Jarvist M. Frost, Young-Kwang Jung +1
Organic-inorganic halide perovskites present a number of challenges for first-principles atomistic materials modelling. These `plastic crystals' feature dynamic processes across mu…
