Abstract
Diamond nucleation and growth on a LaAlO3 single crystal substrate, wh ose lattice mismatch with diamond is only 7.2% at high temperature, we re investigated for the first time. As an insulating substrate, a nucl eation density of more than 10(8) cm(-2) was achieved on ultrasonicall y cleaned wafers. A free-standing diamond film was obtained for 65 h g rowth and characterized by scanning electron microscopy, Raman and x-r ay photoelectron spectroscopy. The results show that LaAlO3 single cry stal is a good candidate substrate for diamond film growth.
