Abstract

Thin films of boron nitride were grown by femtosecond, pulsed laser deposition. The films were analyzed by transmission electron microscopy, Fourier transform infrared spectroscopy and Raman spectroscopy. All the results indicated the presence of wurtzite phase in the thin film in contrast to usual phases such as cubic or hexagonal ones. Moreover, the electron diffraction pattern showed that the size of the wurtzite boron nitride crystallite was larger than 4 μm although boron nitride films reported so far consisted of small crystallites in the nanometer region.
