Non-equilibrium VLS-grown stable ST12-Ge thin film on Si substrate: A study on strain-induced band-engineering
S. Mandal, B. Nag Chowdhury, A. Tiwari +4
The current work describes a novel method of growing thin films of stable crystalline ST12-Ge, a high pressure polymorph of Ge, on Si substrate by a non-equilibrium VLS-technique.…
Effect of 50 MeV Li3+ irradiation on structural and electrical properties of Mn doped ZnO
S. K. Neogi, S. Chattopadhyay, Aritra Banerjee +3
The present work aims to study the effect of ion irradiation on structural and electrical properties and their correlation with the defects in Zn1-xMnxO type system. Zn1-xMnxO (x =…
Optical property modification of ZnO: Effect of 1.2 MeV Ar irradiation
Soubhik Chattopadhyay, Sreetama Dutta, Palash Pandit +7
We report a systematic study on 1.2 MeV Ar^8+ irradiated ZnO by x-ray diffraction (XRD), room temperature photoluminescence (PL) and ultraviolet-visible (UV-Vis) absorption measure…
Controlled defects in ZnO by low energy Ar irradiation
Soubhik Chattopadhyay, Sreetama Dutta, D. Jana +6
We report interesting observations in 1.2 MeV Ar8+ ion irradiated ZnO which, to the best of our knowledge, have not been published earlier and will be useful for the scientific com…
Synthesis and characterization of single phase Mn doped ZnO
Soubhik Chattopadhyay, S. Dutta, Aritra Banerjee +4
Different samples of Zn1-xMnxO series have been prepared by conventional solid state sintering method. It has been identified, up to what extent of doping enable us to synthesize s…
