Figure 2

(a) Constant current STM (at −2.0 V, 15 pA) image (215 nm × 215 nm) of K multilayer film on graphite. Inset, the line profile of the region indicated by the line on the figure. (b) The STM topographic image (40 nm × 40 nm) of the 2nd layer of the K film taken of the area within the red dashed box in (a). (c) The STM topographic image (40 nm × 40 nm) of the 3rd layer of the K film taken of the area within the blue dashed box in (a). (d) The STM topographic image (40 nm × 40 nm) of the 4th layer of the K film taken of the area within the green dashed box in (a).
