Second-order Raman and anharmonic lattice dynamics in lead-halide perovskites
Chao Shen, Florian Kluibenschedl, Ayan A. Zhumekenov +4
We explore the microscopic origin of THz-driven lattice dynamics in methylammonium lead bromide CHNHPbBr using two-dimensional THz Kerr-effect spectroscopy. The analysi…
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…
Observation of Analogue Dynamic Schwinger Effect and Non-Perturbative Light Sensing in Lead Halide Perovskites
Dusan Lorenc, Artem G. Volosniev, Ayan A. Zhumekenov +5
Dielectric breakdown of physical vacuum (Schwinger effect) is the textbook demonstration of compatibility of Relativity and Quantum theory. Although observing this effect is still…
Interferometric determination of intrinsic nonlinear Kerr index in lead-halide perovskites
Dusan Lorenc, Ayan Zhumekenov, Osman M. Bakr +1
Lead halide perovskites have recently been reported to demonstrate an exceptionally high nonlinear (Kerr) refractive index n of up to 10 cm/W in CHNHPbBr…
Elastic softness of hybrid lead halide perovskites
A. C. Ferreira, A. Létoublon, S. Paofai +10
Much recent attention has been devoted towards unravelling the microscopic optoelectronic properties of hybrid organic-inorganic perovskites (HOP). Here we investigate by coherent…
