Web1 day ago · Cesium-based inorganic hybrid halide lead perovskite CsPbX 3 (X = I, Br, Cl) have emerged as a kind of photovoltaic material with immense potential. However, there is still a challenge for the growth of Br-I hybrid CsPbBr 3−X I X single crystals (SCs) to further investigate of CsPbX 3 perovskites. Herein, we present a new method that realizes … WebA crystal dendrite is a crystal that develops with a typical multi-branching form. The name comes from the Greek word dendron (δενδρον) which means "tree", since the crystal's structure resembles that of a tree. …
