论文摘要：Via the combination of theoretical and experimental investigations， we have synthesized the single crystal of pure calcium tetraboride (CaB４) under conditions of high pressure and high temperature。 The Temperature (T)—Pressure (P) phase diagram of Ca-B binary system has been obtained。 The recovered CaB４ after decompression of high pressure is characterized to have a ThB４-type tetragonal structure。 Both the calculated band structure and the measured temperature-dependent resistivity are indicative of the intrinsic metallic property of CaB４ in contrary to the hypothetical semiconducting behavior。
