Abstract
Various reconstructions on the GaN(0001) surface are studied by scanning tunneling microscopy (STM). Based on the comparison between the STM observations and first-principles total-energy calculations, we propose an adatom scheme for the basic and structures, and others as well. It is revealed that the phase consists of a linear chain of unevenly displaced Ga adatoms along the direction due to lattice relaxation.
