It is a cubic ([[sphalerite]]) [[semiconductor]] with a [[lattice constant]] of 0.4777 nm and an [[indirect bandgap]] of roughly 1.5 eV. It can be alloyed with [[gallium arsenide]]. Boron arsenide also occurs as an [[icosahedral]] boride, B<sub>12</sub>As<sub>2</sub>. http://spectra.phy.bris.ac.uk/research_semiconductor.asp This form can be grown on substrates such as [[silicon carbide]]. ==Applications== [[Solar cell]]s can be fabricated from boron arsenide. ==References== {{Citationstyle|date=September 2007}} <references/> * ''Boron Chemistry at the Millennium'', Editor: R.B.
