摘要
GaN is grown by plasma-assisted molecular-beam epitaxy on ZnO(1 (1) over bar 00) substrates. Well-oriented (1 (1) over bar 00) GaN surfaces are obtained, and (1 (1) over bar 01) oriented facets are also observed. On the GaN(1 (1) over bar 00) surfaces under Ga-rich conditions, a surface reconstruction with approximate symmetry of "4x5" is found. A model is proposed in which this reconstruction consists of greater than or equal to2 monolayers of Ga terminating the GaN surface. (C) 2003 American Institute of Physics.
