Figure 1From: Formation of linearly linked Fe clusters on Si(111)-7 × 7-C2H5OH surfaceTypical and standard STM image of Si(111)-7 × 7-reconstructed surface. The typical STM image of Si(111)-7 × 7-reconstructed surface (a), where the inset was the high magnification. And the standard Si(111)-7 × 7-reconstructed surface saturated by C2H5OH (b). During all scanning process, the bias voltage and tunneling current was kept at 1.5 V and 0.19 nA, respectively.Back to article page
