Fabrication of high quality GaN nanopillar arrays by dry and wet chemical etching
Dipak Paramanik, Abhishek Motayed, Matthew King +4
We study strain relaxation and surface damage of GaN nanopillar arrays fabricated using inductively coupled plasma (ICP) etching and post etch wet chemical treatment. We controlled…
Fabrication of InP nano pillars by ECR Ar ion irradiation
D. Paramanik, T. T. Suzuki, N. Ikeda +4
Regular arrays of InP nano pillars have been fabricated by low energy Electron Cyclotron Resonance (ECR) Ar+ ion irradiation on InP(111) surface. Several scanning electron microsco…
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…
Shape Transition of Nanostructures created on Si(100) surfaces after MeV Implantation
S. Dey, D. Paramanik, V. Ganesan +1
We have studied the modification in the Surface morphology of the Si(100) surfaces after 1.5 MeV Sb implantation. Scanning Probe Microscopy has been utilized to investigate the ion…
