Journal ArticleDOI
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
Effect of chemical doping of boron and nitrogen on the electronic, optical, and electrochemical properties of carbon nanotubes
TL;DR: In this paper, the electronic, optical and electrochemical properties along with electronic behaviors of boron (B) and nitrogen (N) substituted Single Wall Carbon Nanotubes (SWCNTs) underlying density functional theory (DFT) simulations are discussed.
Journal ArticleDOI
A theoretical review on electronic, magnetic and optical properties of silicene.
Suman Chowdhury,Debnarayan Jana +1 more
TL;DR: The results obtained so far from experimental and theoretical studies in understanding silicene have shown enough significant promising features to open a new direction in the silicon industry, silicon based nano-structures in spintronics and in opto-electronic devices.
Journal ArticleDOI
Ab-initio calculation of electronic and optical properties of nitrogen and boron doped graphene nanosheet
TL;DR: In this paper, the static dielectric constant in the long wave length limit for parallel polarization of electric field increases with the doping concentration, whereas for perpendicular polarization it remains almost constant with respect to the doping concentrations and specific types.
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.
