Giant Negative Linear Compressibility in Orthorhombic Copper Cyanide
Swayam Kesari, Alka B. Garg, Nilesh P. Salke +1
Most reported negative linear compressibility (NLC) materials exhibit either a small NLC over a large pressure range or a high NLC over a very small pressure range. Here, we report…
Accurate Determination of the Band-Gap Energy of the Rare-Earth Niobate Series
Alka B. Garg, David Vie, Placida Rodriguez-Hernandez +3
In this work, we report diffuse reflectivity measurements in InNbO4, ScNbO4, YNbO4, and eight different rare-earth niobates. From a comparison with the established values of the ba…
High-Pressure Monoclinic-Monoclinic Transition in Fergusonite-type HoNbO4
A. B. Garg, D. Errandonea, P. Rodriguez-Hernandez +1
In this paper we perform a high-pressure study of fergusonite-type HoNbO4. Powder x-ray diffraction experiments and ab initio density-functional theory simulations provide evidence…
Recent progress on the characterization of the high-pressure behaviour of AVO4 orthovanadates
Daniel Errandonea, Alka B. Garg
AVO4 vanadates are materials of technological importance due to their variety of functional properties. They have applications as scintillators, thermophosphors, photocatalysts, ca…
Pressure-induced phase transition and bandgap collapse in the wide-bandgap semiconductor InTaO4
D. Errandonea, C. Popescu, A. B. Garg +7
A pressure-induced phase transition, associated with an increase of the coordination number of In and Ta, is detected beyond 13 GPa in InTaO4 by combining synchrotron x-ray diffrac…
High pressure studies on properties of FeGa3: role of on-site coulomb correlation
Debashis Mondal, Velaga Srihari, C. Kamal +7
High pressure X-ray diffraction measurements have been carried out on the intermetallic semiconductor FeGa and the equation of state for FeGa has been determined. First pri…
