Nanocrystalline materials have shown promise in many applications, such as light-emitting diodes, solar cells, biomedicine, optoelectronics, etc. Shape-controlled nanocrystals are important because different geometries of nanocrystals possess various electronic properties which can be tailored to their application. In this project, Yu will conduct synthesis experiments of Cadmium Telluride (CdTe) by varying the amount of solvent. By analyzing nucleation kinetics in the synthesis of the CdTe, Yu hopes to develop a mechanistic explanation for crystal branching and increase the reproducibility of the tetrapods’ shape syntheses. Moreover, this approach to understanding CdTe tetrapods and their syntheses will contribute to an explanation of thermodynamic and kinetic effects on CdTe’s structure.
