Role of defects in tailoring structural, electrical and optical properties of ZnO
Sreetama Dutta,S. Chattopadhyay,Anindya Sarkar,Mahuya Chakrabarti,Dirtha Sanyal,Debnarayan Jana +5 more
TL;DR: In this paper, a brief account of the evolution of defects due to controlled changes in polycrystalline zinc oxide has been presented and a coherent scenario in the light of previous works in this field has been discussed.
Journal ArticleDOI
Annealing effect on nano-ZnO powder studied from positron lifetime and optical absorption spectroscopy
Sreetama Dutta,S. Chattopadhyay,Debnarayan Jana,A. Banerjee,S.K Manik,Swapan Kumar Pradhan,Manas Sutradhar,Anindya Sarkar +7 more
TL;DR: In this article, different thermal stages of generation and recovery of cationic as well as anionic defects in granular ZnO are discussed in the light of XRD, PAL, and optical absorption studies.
Journal ArticleDOI
Defects and the optical absorption in nanocrystalline ZnO
Sreetama Dutta,S. Chattopadhyay,Manas Sutradhar,Anindya Sarkar,Mahuya Chakrabarti,Dirtha Sanyal,Debnarayan Jana +6 more
TL;DR: In this paper, the structural and optical properties of mechanically milled high purity ZnO powder are investigated and a correlation between the structural properties of the powder and its optical properties is reported.
Journal ArticleDOI
Defects induced ferromagnetism in Mn doped ZnO
Sukalyan Chattopadhyay,S.K. Neogi,Anindya Sarkar,M. D. Mukadam,S. M. Yusuf,Aritra Banerjee,Sudipta Bandyopadhyay +6 more
TL;DR: In this article, single phase Mn doped ZnO samples have been synthesized by the solid-state reaction technique and all the samples were found to be ferromagnetic with clear hysteresis loops at room temperature and the maximum value for saturation magnetization (0.11μB/Mn atom) was achieved for 96h milled sample.
Journal ArticleDOI
Defect dynamics in annealed ZnO by positron annihilation spectroscopy
Sreetama Dutta,Mahuya Chakrabarti,S. Chattopadhyay,Debnarayan Jana,Dirtha Sanyal,Anindya Sarkar +5 more
TL;DR: In this paper, annealing up to 300°C, an increase of defect lifetime (τ2) as well as shape parameter (S parameter) has been observed, which is possibly due to oxygen evaporation from the sample.
