The pursuit of stability in halide perovskites: the monovalent cation and the key for surface and bulk self-repair
D R Ceratti, A V Cohen, R Tenne +12
We find significant differences between degradation and healing at the surface or in the bulk for each of the different APbBr3 single crystals (A=CH3NH3+, methylammonium (MA); HC(N…
The tetragonal phase of CHNHPbI is strongly anharmonic
Rituraj Sharma, Zhenbang Dai, Lingyuan Gao +7
Halide perovskite (HP) semiconductors exhibit unique strong coupling between the electronic and structural dynamics. The high-temperature cubic phase of HPs is known to be entropic…
Halide perovskites under polarized light: Vibrational symmetry analysis using polarized Raman
Rituraj Sharma, Matan Menahem, Zhenbang Dai +9
In the last decade, hybrid organic-inorganic halide perovskites have emerged as a new type of semiconductor for photovoltaics and other optoelectronic applications. Unlike standard…
Type and Degree of Covalence: Empirical Derivation and Implications
Yevgeny Rakita, Thomas Kirchartz, Gary Hodes +1
The way atoms attach to each other defines the function(s), e.g., mechanical, optical, electronic, of a given material. The nature of the chemical bond is, therefore, one of the mo…
Between Structure and Performance in Halide Perovskites for Photovoltaic Applications: the Role of Defects
Yevgeny Rakita, David Cahen, Gary Hodes
My study is about Halide Perovskites (HaPs) and focuses the fundamental structural, chemical and dielectric properties of HaPs in reference to their PV-related properties. * I pres…
