Tetragonal CH3NH3PbI3 is ferroelectric.
Halide perovskite (HaP) semiconductors are revolutionizing photovoltaic (PV) solar energy conversion by showing remarkable performance of solar cells made with HaPs, especially tetragonal methylammonium lead triiodide (MAPbI3). In particular, the low voltage loss of these cells implies a remarkably low recombination rate of photogenerated carriers. It was suggested that low recombination can be...

متن کاملProton Dipolar Spin–Lattice Relaxation in Nano-channels of Natrolite
The 1H nuclear magnetic resonance (NMR) spectra and the dipolar spin-lattice relaxation time T1D for 1H in the natural natrolite (Na2Al2Si3O10·2H2O) have been measured in the temperature range of 190-390 K. From the temperature transformations of 1H NMR spectra, it follows that at T > 300 K, the diffusion of water molecules along the nano-channels is observed. From experimental T1D data, it fol...
متن کاملA Combinatorial Interpretation for Schreyer’s Tetragonal Invariants
Schreyer has proved that the graded Betti numbers of a canonical tetragonal curve are determined by two integers b1 and b2, associated to the curve through a certain geometric construction. In this article we prove that in the case of a smooth projective tetragonal curve on a toric surface, these integers have easy interpretations in terms of the Newton polygon of its defining Laurent polynomia...
متن کاملAnomalous Temperature Dependence of the Heat of Hydration of Natrolite
The temperature dependence of the heat of hydration of natrolite was studied by isothermal adsorption calorimetry from 412 to 472 K. The heat capacity of hydration implied by these results is about 5 times greater than the calorimetric heat capacity of reaction, suggesting atypical behavior across this solid solution.
