Journal Title and Volume Number (to be inserted by the publisher) 2
Fig 1 - Intensity of RHEED specular spot during the Ga desorption from Si-face SiC, under
vacuum, as a function of the exposure time.
Journal Title and Volume Number (to be inserted by the publisher) 3 Structural and optical characterization The High Resolution X-Ray Diffraction (HRXRD) (0002) θ − 2θ and ω scans of both N-polar and Ga-polar GaN on SiC are shown in figure 3.
On the other hand, the emission is more intense for N-polar GaN than for Ga-polar material, which suggests a reduction in the density of non-radiative recombination centers.
Journal Title and Volume Number (to be inserted by the publisher) 4 The inset in fig 4 shows the PL spectrum of a 3 µm N-polar GaN layer at 10 K.
