Boron phosphide (BP) is a promising material for the development of high-efficiency solid-state thermal neutron detectors. However, the synthesis of good-quality BP film had been an obstacle. In this work, silicon carbide (SiC) substrates with vicinal steps instead of the conventional silicon (Si) substrates are used for BP growths. A series of growth experiments are performed and good-quality epitaxial BP films are successfully obtained and for the first time fully characterized. The optimized growth conditions are established, the film growth mechanism and defect origination mechanism are interpreted after an integrated experimental and theoretical study.
