Figure 1: a) B
K-edge x-ray absorption spectra for three BN/Si films. The
x-ray flux was directed onto the films at normal incidence.
Notice the 3 small peaks between the pi* peak at
192.0 eV and the onset of the sigma* band
at 197 eV.
b) B K-edge spectra for hBN, cBN, and rBN powders.
Figure 2: a) N
K-edge x-ray absorption spectra for three BN/Si films. All
data were taken with x-rays at normal incidence.
b) N K-edge spectra for hBN, cBN, and rBN powders.
