In-situ spectroscopic studies of viologen based electrochromic device
Suryakant Mishra, Haardik Pandey, Priyanka Yogi +4
Fabrication and operation of simple solid state electrochromic devices using ethyl viologen diperchlorate in a polymer matrix is presented here. In-situ Raman and transmission/abso…
Role of Metal Nanoparticles on porosification of silicon by metal induced etching (MIE)
Shailendra K. Saxena, Priyanka Yogi, Pooja Yadav +6
Porosification of silicon (Si) by metal induced etching (MIE) process have been studies here to understand the etching mechanism. The etching mechanism has been discussed on the ba…
Micro-Raman and field emission studies of silicon nanowires prepared by metal assisted chemical etching
Vivek Kumar, Shailendra K. Saxena, Vishakha Kaushik +3
Micro-Raman scattering and electron field emission characteristics of silicon nanowires (SiNWs) synthesized by metal assisted chemical etching (MACE) are investigated. Scanning ele…
Fabrication of silicon nanocrystals using sequential Au ion implantation
Gayatri Sahu, Rajesh Kumar, D. P. Mahapatra
Silicon nanocrystals are produced using a two-stage gold ion implantation technique. First stage implantation using low energy ions leads to the formation of an amorphous Si (a-Si)…
Spectroscopic investigation of quantum confinement effects in ion implanted silicon-on-sapphire films
Rajesh Kumar, H. S. Mavi, A. K. Shukla
Crystalline Silicon-on-Sapphire (SOS) films were implanted with boron (B) and phosphorous (P) ions. Different samples, prepared by varying the ion dose in the range $10^{14…
Defect free visible photoluminescence from laser-generated germanium nanoparticles
Manoj Kumar, Rajesh Kumar, Vivek Kumar +1
Origin of room temperature visible photoluminescence (PL) from defect free germanium (Ge) nanoparticles have been discussed here. The Ge nanoparticles produced by laser-induced etc…
