Formation of Se ring-like structures on Au(111) at 200 °C. Large scale STM image (a) and the corresponding FFT image (b) of Se/Au(111). The inset is the zoomed-in image of the area indicated by the white rectangle. Zoomed-in STM image (c) of the region II in panel (a) and the corresponding FFT image (d) of Se/Au(111) in the region II in panel (a). (e) Schematic atomic structures of Se ring-like self-assembled thin film. (f) d I/d V spectrum of the ring-like Se/Au(111). Tunneling conditions: (a) Vbias = 2.0 V, Iset = 1.0 nA; (c) Vbias = 1.0 V, Iset = 500 pA; (f) Vbias = 2.0 V, Iset = 500 pA.
