Journal ArticleDOI
Enhanced room temperature ferromagnetism and green photoluminescence in Cu doped ZnO thin film synthesised by neutral beam sputtering
Dinesh C. Agarwal,Udai B. Singh,Srashti Gupta,Rahul Singhal,Pawan K. Kulriya,Fouran Singh,Ambuj Tripathi,Jitendra Singh,Utpal S. Joshi,D.K. Avasthi +9 more
TL;DR: The enhancement in magnetic moment as well as green emission in photoluminescence response with increase in Cu doping indicates that generation of large defects in ZnO by Cu doping, which can be attributed to combined effect of the presence of oxygen vacancies and/or structural inhomogeneity aswell as formation of bound magnetic polarons.
Journal ArticleDOI
Enhancement of thermoelectric power of PbTe:Ag nanocomposite thin films
Manju Bala,Srashti Gupta,T. S. Tripathi,Shikha Varma,Surya Kant Tripathi,K. Asokan,D.K. Avasthi +6 more
TL;DR: In this article, the enhancement of thermoelectric power of PbTe:Ag nanocomposite thin films, synthesized by the thermal evaporation technique, was investigated.
Journal ArticleDOI
Synthesis of bismuth telluride nanostructures by refluxing method
TL;DR: In this paper, Bismuth telluride (Bi2Te3) nano particles were prepared by refluxing method in different conditions such as varying concentration of KOH and reaction timings.
Journal ArticleDOI
Phase evolution and electrical properties of Co–Sb alloys fabricated from Co/Sb bilayers by thermal annealing and ion beam mixing
Manju Bala,Compesh Pannu,Srashti Gupta,T. S. Tripathi,Surya Kant Tripathi,K. Asokan,D.K. Avasthi +6 more
TL;DR: It was observed that the alloys formed by ion-beam induced mixing exhibited higher electrical conductivity and thermoelectric power than the as-deposited and thermally annealed Co/Sb bilayer thin films.
Journal ArticleDOI
Superiority of ion irradiation over annealing for enhancing the thermopower of PbTe thin films
Srashti Gupta,Dinesh C. Agarwal,Shikhar Tripathi,Sonnathi Neeleshwar,B. K. Panigrahi,Alexandre Jacquot,Bertrand Lenoir,D.K. Avasthi +7 more
TL;DR: In this paper, swift heavy ion (SHI) irradiation enhances thermoelectric properties and the annealing deteriorates the performance of PbTe thin film, and the increase in thermo power (S) is ∼40% upto high temperature (∼520 K).
