According to the hexagonal crystalline nature of InN, the occurrence of both (101 ̅ 0) and (112 ̅ 0) would exhibit six-fold symmetry by fixing 2θ -ω to corresponding angles of either (101 ̅ 0) and (112 ̅ 0) planes and performing in-plane rotation scans (φ = 0 -360°) . In addition to their respective set of six-fold symmetric peaks, a 30 o off-set is expected between these two set. To prove the epitaxial relationship between InN and SiC, the angles for the occurrence of InN are expected to be identical to that of SiC. According to our experimental results (see supporting information, Fig. ), all the criteria described above are fulfilled.
