摘要：
The high pressure structural and transport behaviors of transition metal dichalchogenides NbSexTe2-x (x = 2, 1.5) were investigated using powder X-ray diffraction and resistivity measurements. The structural results show all these title compounds remain stable under application of pressure up to 39 GPa. The lattice compressibilites were determined and show highly anisotropic behavior. A change in superconducting transition temperature dependent on composition was observed. The resistivity measurements performed under pressure for NbSe1.5Te0.5 revealed strong enhancement in transition temperature with T-c increasing from 3.35 K at ambient, to 4.4 K at 1.8 GPa, at a rate of 0.6 K/GPa.
