The faculties in the Department of Physics work in various fields of research. The specific areas are discussed as follows:
(i) Solar Energy Harvesting using Exotic Metal Nanoparticle-Periodically Segmented TiO2 Hybrids for Photocatalytic Applications
Scope: Global warming is having a significant and pricey effects on our climate, health and the entire planet. Carbon dioxide (CO2) contributes effectively to this global climate change and diminishing of fossil fuels reserves. The issue raises a concern on future energy supply and demands and solutions are needed to mitigate the rising levels of CO2. In the direction of development of novel semiconducting nanostructured photocatalytic material, the proposed work demonstrates a facile and cost effective approach in fabricating 1D-periodically segmented TiO2 nanotubes (PSTNs) with programmable microcontroller based galvanostaticanodization. The niche of the controllable galvanostatic anodization is to provide constant current pulses to form periodic segments of TiO2 nanotubes with high surface area. These periodic nanostructures, further will be grafted with metal nanoparticles (MNPs, M=Ag, Au, Pd, Zn) using inert gas thermal evaporation system to form a MNPs-PSTNs hybrids. These high surface area nanohybrids will acts a photocatalyst to harvest solar light for conversion into useful fuels (methane, ethane etc.). The one set of hybrid system will be compared with the another nanohybrid system of metal nanoparticles-TiO2nanorods (MNPs-TNRs), synthesized using hydrothermal method and grafted with MNPs.
(ii) Exciting MoS2nanosheets-one dimensional periodic TiO2 naotubes based heterostructures for light harvesting applications
(iii) Effect of ion irradiation on components of hybrid solar cells
Under this work, the charge carriers generating and transmitting regions of hybrid solar cells are being analyzed by means of ion irradiation and other techniques. The theoretical investigations are also being performed for the same.
(iv) Effect of SHI on photoluminescence properties of BCN/silica composites
(v) A case study for tweeks observed on 23 March 2007 was done and D-region ionospheric reflection heights, electron density and propagation distances in the earth-ionosphere wave guide from causative lightning discharge with respect to Allahabad station was estimated by analyzing first cutoff frequency of tweeks. A comprehensive analysis of 1 year tweek data was done to study tweek occurrence characteristic during different seasons of a year and also during local night. Tweek atmospherics have been used to study the quiet time D-region variability in order to derive D-region base line in order to accurately estimate and electron density variation caused by various geophysical process. We also used tweek atmospheric to study effect of 22 July 2009 total solar eclipse on lower ionosphere. Direction finding technique is applied for tweeks observed at Allahabad and Nainital and source position of causative lightning discharge is estimated. We have obtained first direct correlation between whistlers observed at a low latitude station Allahabad with their causative lightning discharges located near the conjugate region using GLD 360 lightning network data.
