Thermodynamically and Kinetically Controlled Nucleation and Growth of Halide Perovskite Single Crystals (Small 48/2023)

Halide Perovskite Single Crystals In article number 2304900, Dong Zhang, Takuya Okamoto, and Vasudevanpillai Biju show size-controlled, monodisperse cubic halide perovskite crystal formation by thermodynamically controlling the nucleation-crystal growth kinetics in inverse temperature crystallization. The concentration of N-cyclohexyl-2-pyrrolidone and the nucleation-growth temperature play central roles in the shape and size of crystals. Controlled growth with the pyrrolidone derivative suppresses the defect density of the crystals, producing uniform samples for optoelectronic and photovoltaic applications.
