最新ZnO Review（accept manuscript）：Role of defects
|
||
|
做ZnO的虫子们，来看那，好的话支持一下 Title ： Role of defects in tailoring structural, electrical and optical properties of ZnO Abstract: In this short topical review, a brief account of the evolution of defects due to controlled changes in polycrystalline zinc oxide has been presented. X-ray diffraction, Positron annihilation spectroscopy and optical absorption spectroscopy has been employed to understand various defective states of ZnO. Thermogravimetric analysis, room temperature resistivity and photoluminescence measurements (just mentioned) have been used to throw more light on this topic. A coherent scenario in the light of previous works in this field has been discussed. At the end discussion on the magnetic studies on ZnO based systems has been added in short. Contents 1. Introduction 1.1 General 1.2 Defect physics and chemistry in ZnO 1.3 Some recent developments and the scope of this review 2. Sample preparation, conditioning and scientific motivation 2.1. Heat-treatment (annealing) 2.2. Mechanical milling (ball-milling) 2.3. Milling and subsequent annealing 2.4. Ion-beam irradiation 3.
