N2 - We have studied the atomic and electronic structure of the Cu (001) - (20x20) R26.6°-In surface, which undergoes a reversible transition to a p (2x2) phase at high temperature. Low temperature scanning-tunneling microscopy indicates a p (2x2) structure modulated at the (20x20) periodicity. Angle-resolved photoelectron spectroscopy shows a surface resonance exhibiting gap opening and backfolding along a (20x20) zone boundary. We suggest that the (20x20) structure is stabilized due to the Fermi surface nesting accompanying a surface charge density wave.
