We report the superconductivity enhancement of ZrTe3 on compression up to 33 GPa. The superconducting transition occurs above 4.1 GPa and temperature (T C) increases with pressure in further compression, reaching a maximum 7.1 K at ~28 An anomalous change is seen 21 No structural phase observed whole 36 GPa, but subtle parameter between 17-19 which seems relevant increase temperature. First-principle calculations reveal that density states Fermi level pressure, explains T C under compression.
We conducted a systematic study on pressure-dependent electrical, vibrational and structural properties of titanium ditelluride up to 43.4 GPa. The room-temperature resistivity shows series anomaly changes at around 6, 13 22 Low-temperature resistance measurement was also employed better understand the electronic structure we observed superconductivity about 6 GPa successfully. Raman spectroscopy X-ray diffraction (XRD) experiment show topological phase transition followed by P 3 m1 C2/m...
