Polymorph growth of inorganic functional materials

Continuous development of liquid/solid interface towards the liquid side promotes crystal growth under the chemical reaction among crystal constituents. Here, factors that determine inorganic functional materials are analyzed by establishing the chemical reaction equations at liquid/solid interface. The linear growth velocity along the [uvw] direction is directly determined by the chemical bonds formed in chemical reaction at the growing interface. In the present chemical bonding growth model, both thermodynamic and kinetic controls are integrated, which can also be classified in particular materials growth system. Taking Cu 2 O as an example, we demonstrate that the critical control factor is the bonding mode in linking Cu 2 O growth units controlled by chemical reaction, and various bonding modes promote the polymorph growth of inorganic functional materials.
