Reversed crystal growth of ZnO microdisks
by Self, Katherine; Zhou, Huajun; Greer, Heather F.; Tian, Z. Ryan; Zhou, Wuzong
Hexagonal ZnO microdisks are grown and then selectively dissolved to form microstadiums. Analysis of the growth and dissolution of the microdisks revealed that they follow a reversed crystal growth mechanism, i.e. aggregation of precursors followed by surface crystallization and extension of crystallization from the surface to the core.
