Journal ArticleDOI
Sb concentration dependent structural and resistive properties of polycrystalline Bi-Sb alloys
K. Malik,Diptasikha Das,Debashis Mondal,Dipankar Chattopadhyay,A. K. Deb,Sudipta Bandyopadhyay,Aritra Banerjee +6 more
TL;DR: In this article, a detailed structural analysis of the samples and lattice parameters of polycrystalline Bi1−xSbx alloys have been estimated using Rietveld refinement technique, utilizing maud software.
Journal ArticleDOI
Enhanced ferromagnetism by ion irradiation for substitutionally cobalt doped ZnO films
TL;DR: In this paper, the effect of Ar ion beam irradiation is highly enhanced ferromagnetism and proper Co substituted ZnO film was demonstrated from UV-visible spectra by d-d transition.
Journal ArticleDOI
Transport Properties of As‐Prepared Al‐Doped Zinc Oxide Films Using Sol–Gel Method
TL;DR: In this article, two ZnO films doped with different concentrations of aluminum (AZO) have been prepared by the sol-gel technique and the electrical properties of the samples have been measured on as-deposited films.
Journal ArticleDOI
Tuning of thermoelectric properties with changing Se content in Sb2Te3
Diptasikha Das,K. Malik,A. K. Deb,V. A. Kulbachinskii,Vladimir G. Kytin,Souvik Chatterjee,Sandip Dhara,Sudipta Bandyopadhyay,Aritra Banerjee +8 more
TL;DR: In this paper, the structural analysis of polycrystalline Sb2Te3−x Se x samples was carried out by the solid-state reaction method and it was shown that up to the maximal concentration of Se, the samples possess rhombohedral crystal symmetry (space group ).
Journal ArticleDOI
Correlation between defect and magnetism of low energy Ar+9 implanted and un-implanted Zn0.95Mn0.05O thin films suitable for electronic application
S.K. Neogi,N. Midya,Pallabi Pramanik,Aritra Banerjee,Anirban Bhattacharyya,G. S. Taki,J.B.M. Krishna,Sudipta Bandyopadhyay +7 more
TL;DR: The structural, morphological, optical and magnetic properties of Ar +9 implanted 5% Mn doped ZnO films have been investigated to detect the correlation between ferromagnetism (FM) and defect as mentioned in this paper.
