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…
Bond polarizability as a probe of local crystal fields in hybrid lead-halide perovskites
Yujing Wei, Artem G. Volosniev, Dusan Lorenc +4
A rotating organic cation and a dynamically disordered soft inorganic cage are the hallmark features of hybrid organic-inorganic lead-halide perovskites. Understanding the interpla…
Effective model for studying optical properties of lead-halide perovskites
Artem G. Volosniev, Abhishek Shiva Kumar, Dusan Lorenc +5
We use general symmetry-based arguments to construct an effective model suitable for studying optical properties of lead-halide perovskites. To build the model, we identify an atom…
Spin-Electric Coupling in Lead Halide Perovskites
Artem G. Volosniev, Abhishek Shiva Kumar, Dusan Lorenc +5
Lead-halide perovskites enjoy a number of remarkable optoelectronic properties. To explain their origin, it is necessary to study how electromagnetic fields interact with these sys…
Visualizing buried local carrier diffusion in halide perovskite crystals via two-photon microscopy
Camille Stavrakas, Géraud Delport, Ayan A. Zhumekenov +5
Halide perovskites have shown great potential for light emission and photovoltaic applications due to their remarkable electronic properties and compatibility with cost-effective f…
