Journal ArticleDOI
Zinc vacancy and oxygen interstitial in ZnO revealed by sequential annealing and electron irradiation
K. E. Knutsen,Augustinas Galeckas,A. Zubiaga,Filip Tuomisto,G. C. Farlow,B. G. Svensson,A. Yu. Kuznetsov +6 more
TL;DR: In this article, a strong indication that oxygen interstitials act as dominating acceptor is derived from the analysis of charge carrier losses induced by electron irradiation with variable energy below and above the threshold for Zn-atom displacement.
Journal ArticleDOI
Identification of substitutional Li in n-type ZnO and its role as an acceptor
Klaus Magnus H Johansen,A. Zubiaga,Ilja Makkonen,Filip Tuomisto,P. T. Neuvonen,K. E. Knutsen,Edouard Monakhov,A. Yu. Kuznetsov,B. G. Svensson +8 more
TL;DR: Identification of substitutional Li in n-type ZnO and its role as an acceptor is presented.
Journal ArticleDOI
Prediction of high efficiency ZnMgO/Si solar cells suppressing carrier recombination by conduction band engineering
TL;DR: In this paper, an optimal design of an n-Zn0.8Mg0.2O/p-Si solar cell was proposed to achieve high conversion efficiency.
Journal ArticleDOI
H and Li Related Defects in ZnO and Their Effect on Electrical Properties
TL;DR: Li and H are important electrically active impurities in ZnO and as discussed by the authors presented a detailed experimental and computational study of the behavior of H and Li and their effect on its defect structure.
Journal ArticleDOI
Thermal process dependence of Li configuration and electrical properties of Li-doped ZnO
TL;DR: In this paper, depth-resolved cathodoluminescence spectroscopy (DRCLS) was used to describe the strong dependence of Li acceptor formation on thermal treatment in Li-doped ZnO.
