| 英文摘要 | Thick nonpolar (10 (1) over bar0) gan layers were grown on m-plane sapphire substrates by hydride vapor phase epitaxy (hvpe) using magnetron sputtered zno buffers, while semipolar (10 (1) over bar(3) over bar) gan layers were obtained by the conventional two-step growth method using the same substrate. the in-plane anisotropic structural characteristics and stress distribution of the epilayers were revealed by high. resolution x-ray diffraction and polarized raman scattering measurements. atomic force microscopy (afm) images revealed that the striated surface morphologies correlated with the basal plane stacking faults for both (10 (1) over bar0) and (10 (1) over bar(3) over bar) gan films. the m-plane gan surface showed many triangular-shaped pits aligning uniformly with the tips pointing to the c-axis after etching in boiled koh, whereas the oblique hillocks appeared on the semipolar epilayers. in addition, the dominant emission at 3.42ev in m-plane gan films displayed a red shift with respect to that in semipolar epilayers, maybe owing to the different strain states present in the two epitaxial layers.
