Figure 1

STM images of Au(100) after deposition of: (a) 0.05 ML Pt; (b) layer from (a) after subsequent annealing at 50, 80 and 100 °C for 10 min; (c,d) 0.3 ML; (e,f) 0.5 ML Pt. Taken for: (a) U =  + 758 mV; I = 2.1 nA; (b) U =  + 9 mV; I = 5.4 nA; (c) U = − 464 mV; I = 4.5 nA; (d) U = − 3 mV; I = 5.3 nA; (e,f) U =  + 3 mV; I = 4.7 nA.
