Table 2

Comparison of the results obtained for GaN single crystals and GaN epilayers.
GaN single crystals GaN epilayers
n1(lambda = 632.8 nm) = 2.337 ± 0.010 n1(lambda = 632.8 nm) = 2.328 ± 0.003
n2 approxequal 0.003
for: 400 nm < lambda < 800 nm
n2 = 0.0005 for lambda = 680 nm
n2 = 0.0007 for lambda = 500 nm
roughness (top-bottom) of 0.5-3 nm top-layer < 1 nm
