| Outline of Final Research Achievements |
This study aimed at fabricating a high-quality cubic-type boron nitride (c-BN) thin films for a deep-UV light-emitting diode by integrated pulsed laser deposition method. A diamond-like carbon (DLC) films with high sp3 content and with very flat surface morphology were prepared by PLD using a frozen cyclohesane target. A thin film composed of c-BN and B2O3 was formed by PLD of a frozed borazine target with high intensity laser pulses. B2O3 was formed by laser ablation of a B(OH)3 which was produced by chemical reaction of borazine with water molecules during laser irradiation.
