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…
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…
Multiferroic CuCrO2 under High Pressure: In-Situ X-Ray Diffraction and Raman Spectroscopic Studies
Alka B. Garg, A. K. Mishra, K. K. Pandey +1
The compression behavior of delafossite compound CuCrO2 has been investigated by in-situ x-ray diffraction and Raman spectroscopic measurements upto 23.2 and 34 GPa respectively. X…
