ABSTRACT
In/Si(111) surfaces have a variety of phases, among which 4×1 and √7×√3 show intriguing one-/two-dimensional (1D/2D) electronic properties. Here, we carry out extensive experiments to investigate the mechanical properties various phases on by atomic force microscopy at room temperature. Energy dissipation associated with flexibility is measured scale. In phase, locally increases inner parts couples chains, correspond mobile atoms in dynamical fluctuation model for phase transition. An extremely large signal obtained indicating that single layer weakly attached Si substrate, consistent 2D
