Direct growth of a GaN layer on (0 0 0 1) 6H-SiC by low-pressure MOVFE
(LP-MOVPE) with a flow channel is investigated. In this study, we hav
e reported that the surface morphologies of GaN epitaxial layer depend
on the gas flow velocity. A high flow velocity is required for a two-
dimensional(2D) growth. (C) 1998 Published by Elsevier Science B.V. Al
