Examining Experimental Raman Mode Behavior in Mono- and Bi-layer 2H-TaSe via Density Functional Theory
Sugata Chowdhury, Heather M. Hill, Albert F. Rigosi +5
Tantalum diselenide (TaSe) is a metallic transition metal dichalcogenide whose equilibrium structure and vibrational behavior strongly depends on temperature and thickness, i…
Microwave spectroscopy of the low-temperature skyrmion state in Cu2OSeO3
Aisha Aqeel, Jan Sahliger, Takuya Taniguchi +7
In the cubic chiral magnet Cu2OSeO3 a low-temperature skyrmion state (LTS) and a concomitant tilted conical state are observed for magnetic fields parallel to <100>. In this work,…
Nature of native atomic defects in ZrTe and their impact on the low-energy electronic structure
B. Salzmann, A. Pulkkinen, B. Hildebrand +9
Over the past decades, investigations of the anomalous low-energy electronic properties of ZrTe have reached a wide array of conclusions. An open question is the growth method'…
Structural phase transition and bandgap control through mechanical deformation in layered semiconductors 1T-ZrX2 (X = S, Se)
Edoardo Martino, David Santos-Cottin, Florian Le Mardele +10
Applying elastic deformation can tune a material physical properties locally and reversibly. Spatially modulated lattice deformation can create a bandgap gradient, favouring photo-…
Influence of Dimensionality on the Charge Density Wave Phase of 2H-TaSe
Sugata Chowdhury, Albert F. Rigosi, Heather M. Hill +5
Metallic transition metal dichalcogenides like tantalum diselenide (TaSe) exhibit exciting behaviors at low temperatures, including the emergence of charge density wave (CDW)…
Patterns and driving forces of dimensionality-dependent charge density waves in 2H-type transition metal dichalcogenides
Dongjing Lin, Shichao Li, Jinsheng Wen +8
Two-dimensional (2D) materials have become a fertile playground for the exploration and manipulation of novel collective electronic states. Recent experiments have unveiled a varie…
