Zinc peroxide precursor for ZnO clusters

Abstract

Zinc peroxide is suggested as a new precursor for formation of zinc oxide clusters. (ZnO) n , n=1 -100 clusters have been produced by laser ablation of bulk powder of zinc peroxide and studied by time-of-flight mass spectroscopy.

The study of the behavior of Al impurity in ZnO lattice by a fullerene like model

“…As the basis of the model, an isolated FL Zn32Al4O36 cluster was chosen to study its cohesive and electronic properties with different distribution of Al-O pairs [2,8], the defect formation energies of VZn [8], effect of intrinsic Oi defects [1], and packing defects on the electroactivity of the Al impurity in the ZnO lattice. Qualitative results for the behavior of Al impurity in FL cluster based on ZnO were obtained [8].…”

“…The choice of such cluster as a model for ab initio quantum chemical study is due to the fact that isolated (ZnO)n clusters exist really and have been synthesized experimentally [2]. The information about formation of isolated clusters (ZnO)n, where n = 1 -100, was published in [2,3]. The authors reported that zinc oxide clusters have been processed by laser ablation of zinc peroxide in vacuum and investigated by time-of-flight (TOF) mass spectroscopy.…”
