Abstract
The lowest energy structures of ZnS quantum dots of different sizes have been determined by an unbiased search using genetic algorithm (GA) coupled with the density-functional tight-binding method. The GA search converges to a rather new ringlike configurations of ZnS quantum dots. We have studied the structural, electronic, and optical properties of these ringlike clusters and compared these properties with those of other reported structures of ZnS quantum dots, namely, hollow, zinc-blende, wurtzite, and rocksalt structures.
