A copper matrix composite reinforced by β-LiAlSiO4 with negative thermal expansion coefficient was fabricated using vacuum hot-pressed sintering technique. The
β-Ga2O3∶Cr single crystals have potential applications for tunable laser. In β-Ga2O3 crystal structure Cr3+ ions are in octahedron other than tetrahedron. So
The Cd1-xZnxTe(CZT) single crystals were annealed by a two-step method including a vapor-environment step and a liquid-environment step in sequence. The effects
Testing results shows that alloying with Ce and Y improves the hardness and softens temperature of cold worked Cu-Cr-Zr alloys obviously, while the conductivity
