Mid-IR non-volatile silicon photonic switches using nanoscale Ge\textsubscript{2}Sb\textsubscript{2}Te\textsubscript{5} embedded in SOI waveguide
Nadir Ali, Rajesh Kumar
We propose and numerically analyze the hybrid Si-Ge\textsubscript{2}Sb\textsubscript{2}Te\textsubscript{5} strip waveguide switches for Mid-IR wavelength of 2.1 m. The switches…
Three-fold Constructive Perturbation for Significant Enhancement in Field Emission from Nickel Oxide Nano-Thorn
Suryakant Mishra, Priyanka Yogi, Shailendra K. Saxena +3
A power efficient and stable field emission (FE) has been reported here from Nickel Oxide nanostructures. Modification in device geometry and surface micro- (nano-) structure has b…
Metastable behavior of Urbach tail states in BaTiO3 across phase transition
Vikash Mishra, Archna Sagdeo, Kamal Warshi +4
The temperature dependent diffuse reflectance spectroscopy measurements were carried out on the polycrystalline samples of BaTiO3 across the tetragonal to cubic structural phase tr…
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…
Optical bandgap and bowing parameter for Fe doped LaGaO3
P. R. Sagdeo, Preetam Singh, Hari Mohan Rai +3
The polycrystalline samples of LaGa1-xFexO3 have been prepared by standard solid state reaction route. The phase purity of the prepared samples is confirmed by powder xray diffract…
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…
