We applied photoreflectance (PR) spectroscopy for contactless determination of the electric field strength at buried interfaces in metal–insulator–semiconductor (MIS) structures. The PR is an all-optical version of an electromodulated reflectance

Of late, tremendous research efforts have been made to obtain Pb-free low-toxicity halide perovskites. In this regard, the Sn-based perovskite is the focus of attention because of its properties being similar to those of Pb. This paper explores the f

We applied room-temperature photoluminescence (PL) spectroscopy for the compositional engineering of a CH3NH3Pb(Cl,I)3 light harvester in an alloy-based perovskite solar cell. This spectroscopic characterization determines the optimal Cl concentratio

Hydroxyapatite (HA), the main component of living hard tissues, owes its specificity to electrical anisotropy resulting from its hexagonal crystal structure. The strong demand for technology to control the crystal orientation prompted us to develop t
