Metastability Triggered Reactivity in Clusters at Realistic Conditions: A Case Study of N-doped (TiO) for Photocatalysis
Shikha Saini, Pooja Basera, Manish Kumar +2
Here we report a strategy, by taking a prototypical model system for photocatalysis (viz. N-doped (TiO) clusters), to accurately determine low energy metastable structures…
Theoretical insights of codoping to modulate electronic structure of TiO and SrTiO for enhanced photocatalytic efficiency
Manish Kumar, Pooja Basera, Shikha Saini +1
TiO and SrTiO are well known materials in the field of photocatalysis due to their exceptional electronic structure, high chemical stability, non-toxicity and low cost. How…
Role of Defects in Photocatalytic Water Splitting: Monodoped vs Codoped SrTiO
Manish Kumar, Pooja Basera, Shikha Saini +1
Using the hybrid density functional theory and \textit{ab initio} atomistic thermodynamics, we report monodoping of non-metal (N) or metal (Mn) in SrTiO can induce visible ligh…
Self energy and excitonic effect in (un)doped TiO anatase : A comparative study of hybrid DFT, GW and BSE to explore optical properties
Pooja Basera, Shikha Saini, Saswata Bhattacharya
TiO anatase has its significant importance in energy and environmental research. However, the major drawback of this immensely popular semi-conductor is its large bandgap of 3.…
Oxygen vacancy mediated cubic phase stabilization at room temperature in pure nano-crystalline Zirconia films: A combined experimental and first-principles based investigation
Parswajit Kalita, Shikha Saini, Parasmani Rajput +6
We report the formation of cubic phase, under ambient conditions, in thin films of Zirconia synthesized by electron beam evaporation technique. The stabilization of the cubic phase…
Structure and electronic properties of transition-metal/Mg bimetallic clusters at realistic temperatures and oxygen partial pressures
Shikha Saini, Debalaya Sarker, Pooja Basera +3
Composition, atomic structure, and electronic properties of TMMgO clusters (TM = Cr, Ni, Fe, Co, ) at realistic temperature and partial oxygen pressure…
