Dynamic disorder in Bi sub-lattice of $δ$ -Bi $_{2}$ O $_{3}$

Rituraj Sharma, Nimrod Benshalom, Maor Asher +4

$δ$ -Bi $_{2}$ O $_{3}$ is one of the fastest known solid oxide ion conductors owing to its intrinsically defective fluorite-like structure with 25\% vacant sites in the O sub-lattice. Num…

The tetragonal phase of CH $_{3}$ NH $_{3}$ PbI $_{3}$ 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…

Designing hybrid graphene oxide- gold nanoparticles for nonlinear optical response: Experiment and theory

Rajesh Kumar Yadav, J. Aneesh, Rituraj Sharma +6

Nonlinear optical absorption of light by materials are weak due to its perturbative nature, although a strong nonlinear response is of crucial importance to applications in optical…
