  • Low-Temperature Microstructural Studies on Superconducting CaFe₂As₂ 

    Huyan, S.; Deng, L. Z.; Wu, Z.; Zhao, K.; Sun, J. Y.; Wu, L. J.; Zhao, Y. Y.; Yuan, H. M.; Gooch, M.; Lv, Bing; Zhu, Y.; Chen, S.; Chu, C. W. (Nature Publishing Group, 2019-04-23)
    Undoped CaFe₂As₂ (Ca122) can be stabilized in two slightly different non-superconducting tetragonal phases, PI and PII, through thermal treatments. Upon proper annealing, superconductivity with a T_{c} up to 25 K emerges ...

  • High Thermal Conductivity in Isotopically Enriched Cubic Boron Phosphide 

    Zheng, Q.; Li, S.; Li, C.; Lv, Y.; Liu, X.; Huang, P. Y.; Broido, D. A.; Lv, Bing; Cahill, D. G.
    Zinc blende boron arsenide (BAs), boron phosphide (BP), and boron nitride (BN) have attracted significant interest in recent years due to their high thermal conductivity (Λ) predicted by first-principles calculations. This ...

  • High Thermal Conductivity in Cubic Boron Arsenide Crystals 

    Li, Sheng; Zheng, Q.; Lv, Y.; Liu, Xiaoyuan; Wang, X.; Huang, P. Y.; Cahill, D. G.; Lv, Bing
    The high density of heat generated in power electronics and optoelectronic devices is a critical bottleneck in their application. New, high thermally-conducting materials are needed to effectively dissipate heat and thereby ...
