Alignment-free ultra-broadband parametric frequency conversion in lead-halide perovskites
Abhishek Shiva Kumar, Dusan Lorenc, Ayan A. Zhumekenov +2
Lead-halide perovskites were demonstrated to exhibit some of the largest known optical nonlinearities, yet their potential for frequency conversion remains largely untapped. Here w…

Spontaneous flexoelectricity in cubic lead-halide perovskite MAPbBr
Dmytro Rak, Dusan Lorenc, Ayan A. Zhumekenov +2
Lead-halide perovskites exhibit remarkable efficiency in photovoltaics, driven by exceptionally long carrier diffusion lengths and recombination times. Paradoxically, this performa…
