        Summary 
        Image of  surface reconstruction on a clean Gold ( Au( 100)) surface, as visualized using  scanning tunneling microscopy. The individual  atoms composing the material are visible. Surface reconstruction causes the surface atoms to deviate from the bulk  crystal structure, and arrange in columns several atoms wide with regularly-spaced pits between them.
        Technical details 
        Atomically resolved STM image of clean Au(100). This image is made with an Omicron Low Temperature STM and RHK Technology electronics by Erwin Rossen, Eindhoven University of Technology, 2006. Parameters: p<1e-11 mbar, T=77 K, I_setpoint=6 nA, V_bias=1 mV, Au(100) surface is Ar sputtered (1,5 kV, 2uA, 30 minutes) and annealed (500°C, 30 minutes).
