Abstract
Section titled āAbstractāRecent calculations predict a super-thermal-conductivity of ā¼2000 Wm-1K-1, comparable to that of diamond, in cubic boron arsenide (BAs) crystals, which may offer inexpensive insulators with super-thermal-conductivity for microelectronic device applications. We have synthesized and characterized single crystals of BAs with a zinc blende cubic structure and lattice parameters of a = 4.7830(7) Ć . A relatively high thermal conductivity of ā¼200 Wm-1K-1is obtained, close to those of best non-carbon crystal insulators, such as SiC, although still an order of magnitude smaller than the value predicted. Based on our XPS, X-ray single crystal diffraction, and Raman scattering results, steps to achieve the predicted super-thermal conductivity in BAs are proposed.
