Abstract

Perovskites are materials with the chemical formula ABX3 and crystal structure composed commonly by corner-sharing octahedra. Materials with this crystal structure can have a huge variety of applications, including ferroelectrics and more recently photovoltaics. This last application uses halide perovskites, where the X element is a halide. Perovskites can also belong to the class of quantum materials, with properties that are different from usual textbook physics. With this SPRINT project the groups from São Paulo and Medellin will boost their historical collaboration performing studies on perovskites (both as halide perovskites and quantum materials). This project also aims contribute further to the current FAPESP project (process number 21/14422-0) "Computational design of stable Halide Perovskites: effects of defects, alloys, and pressure"and to foster the construction of a new, large project (FAPESP thematic) involving both groups.
