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…
New route for stabilization of 1T-WS2 and MoS2 phases
Andrey N. Enyashin, Lena Yadgarov, Lothar Houben +5
The phenomenon of a partial 2H\rightarrow1T phase transition within multiwalled WS2 nanotubes under substitutional Rhenium doping is discovered by means of high-resolution transmis…
