Anisotropic super-paramagnetism in cobalt implanted rutile-TiO2 single crystals
Shalik Ram Joshi, B. Padmanabhan, Anupama Chanda +4
We study the magnetic properties of single crystals of rutile TiO2 implanted with cobalt for various fluences. The temperature variation of zero field cooled(ZFC) and field cooled…
Enhanced Photoabsorption from Cobalt Implanted Rutile TiO2 (110) Surfaces
Shalik Ram Joshi, B. Padmanabhan, Anupama Chanda +5
Present study investigates the photoabsorption properties of single crystal rutile TiO2 (110) surfaces after they have been implanted with low fluence of Cobalt ions. The surfaces,…
Kinetic Monte Carlo simulations of self organized nanostructures on Ta Surface Fabricated by Low Energy Ion Sputtering
Shalik Ram Joshi, Trilochan Bagarti, Shikha Varma
Surfaces bombarded with low energy ion beams often display development of self assembled patterns and quasi-periodic structures. Kinetic Monte Carlo simulations have been performed…
Studies of self-organized Nanostructures on InP(111) surfaces after low energy Ar+ ion irradiation
D. Paramanik, S. Majumdar, S. R. Sahoo +2
We report formation of self organized InP nano dots using 3 keV Ar+ ion sputtering, at incidence from surface normal, on InP(111) surface. Morphology and optical propert…
Raman Scattering Characterization and Electron Phonon Coupling Strength for MeV implanted InP(111)
D. Paramanik, S. Varma
Structural modifications in InP(111) due to 1.5 MeV implantation of Sb have been characterized using first order and second order Raman spectroscopy. With both Longitudinal Optical…
Nanoscale Defect Formation on InP(111) Surfaces after MeV Sb Implantation
Dipak Paramanik, Asima Pradhan, Shikha Varma
We have studied the surface modifications as well as the surface roughness of the InP(111) surfaces after 1.5 MeV Sb ion implantations. Scanning Probe Microscope (SPM) has been uti…
