We combine structural and magnetic measurements to compare the different phase diagrams between pressure substitution studies in ${\mathrm{CeTiGe}}_{3}$. report on structural, magnetic, electrical transport properties of single crystals ${\mathrm{CeTi}}_{1\ensuremath{-}x}{\mathrm{V}}_{x}{\mathrm{Ge}}_{3}$ ($x=0$, 0.1, 0.2, 0.3, 0.4, 0.9, 1), polycrystalline samples ($x=0.5$, 0.6, 0.7, 0.8), as well ${\mathrm{CeTiGe}}_{3}$ under up $9\phantom{\rule{0.16em}{0ex}}\mathrm{GPa}$. The...
We report pressure-induced superconductivity in a ternary and nonmagnetic Cu-containing semiconductor, Cu2Br2Se6, with wide band gap of 1.89 eV, which the Cu Br atoms generate infinite 21 helical chains along c-axis are linked by cyclohexane-like Se6 rings to form three-dimensional framework. find that this framework is remarkably robust under compression, ambient-pressure phase survives at least our experimental limit 32.1 GPa. Concurrent semiconductor-to-metal transition observed above...
We present a simple and effective approach to improve X-ray data collected under extreme conditions of pressure temperature. The the sample amorphous, liquid, or crystalline transmitting media (PTM) which surround are separately at each temperature, allowing satisfactory background subtraction. Using this method, we able identify weak diffraction peaks low-Z elements Li Na amorphous silica cryogenic temperatures. In addition exploration phase diagrams materials, method can also be applied...
