The ability to tune the shapes of materials directly relates to the ability to tune their properties and stabilities because crystal shape dictates the interfacial atomic arrangement of the material. Therefore, developing a method that enables systematic tuning of materials is as critical for the advancement of materials science as discovering new materials or compositions. Precise crystal shape regulation can be achieved when two basic growth processes, crystal habit formation and branching growth, can be independently and systematically controlled. Crystal habit is determined by the relative order of surface energies of different crystallographic planes of a crystal while branching/dendritic growth is created by a diffusion effect. Therefore, habit and branching formation can be methodically modified by altering growth conditions that affect the thermodynamics and kinetics of the crystallization process. In this presentation, we will discuss our new strategies of directing shapes of inorganic crystals via electrodeposition (e.g. cuprous oxide, zinc). By establishing key conditions that control shape-guiding processes in electrocrystallization, and utilizing the unique capability of electrodeposition to pause and resume crystallization at any stage, we will demonstrate how a vast array of new crystal morphologies that can be produced by rational design of the growth conditions and growth history.
