摘要

A (1×1) ordered monolayer of thallium atoms on a Si(lll) surface has promising potential as a material generating spin-polarized electrons [Sakamoto et al, Phys. Rev. Lett. 102, 096805 (2009)]. In an ideal form the surface is nonmetallic [Lee et al, Phys. Rev. B 66, 233312 (2002)]. Our scanning-tunneling microscopy and spectroscopy study of the (1×1)-Tl surface shows clearly its metallic-like character. On the surface, intrinsic regularly shaped defects with increased density of states near the Fermi level are observed. The relationship between the presence of the defects, which we interpret as Tl multivacancies induced by Si adatoms, and metallicity of the layer is briefly discussed.
