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…
Structural, Vibrational, and Electronic Behavior of Two GaGeTe Polymorphs under compression
Enrico Bandiello, Samuel Gallego-Parra, Akun Liang +14
GaGeTe is a layered topological semimetal that has been recently found to exist in at least two different polytypes, -GaGeTe () and -GaGeTe (). Here we re…
Stress-Tuned Optical Transitions in Layered 1T-MX2 (M= Hf, Zr, Sn; X= S, Se) Crystals
Miłosz Rybak, Tomasz Woźniak, Magdalena Birowska +5
Optical measurements under externally applied stresses allow us to study the materials' electronic structure by comparing the pressure evolution of optical peaks obtained from expe…
Characterization and decomposition of the natural van der Waals heterostructure SnSb2Te4 under compression
Juan A. Sans, Rosario Vilaplana, E. Lora Da Silva +16
This joint experimental and theoretical study of the structural, vibrational and electrical properties of rhombohedral SnSb2Te4 at high pressure unveils the internal mechanisms of…
Phase segregation in MgZnO probed by optical absorption and photoluminescence at high pressure
V. Marín-Borrás, J. Ruiz-Fuertes, A. Segura. +1
The appearance of segregated wurtzite MgZnO with low Mg content in thin films with affected by phase separation, cannot be reliably probed with crystallographic…
Optical and structural study of the pressure-induced phase transition of CdWO
J. Ruiz-Fuertes, A. Friedrich, D. Errandonea +5
The optical absorption of CdWO is reported at high pressures up to 23 GPa. The onset of a phase transition was detected at 19.5 GPa, in good agreement with a previous Raman spe…
