Antimony nanostructures fabricated on metal oxide layers are essential for practical applications in fields of solar cells, electronic and photonic devices. Here the antimony phases were systemically studied on the copper oxide of Cu(110). By high-resolution scanning tunneling microscopy (STM), we revealed that a wrinkled antimony phase was formed on the CuO surface regardless of the initial oxide structure. It exhibited an armchair-like configuration making up of protruded and dipped Sb atoms as confirmed by STM and density functional theory calculations. Further Sb deposition caused the armchair-like phase distorting and subsequently gave rise to formation of a c(2 × 2)-Sb phase. Finally, another kind of wrinkled phase was successfully fabricated. It consisted of two zigzagged antimony chains with protruded and dipped Sb atoms alternately distributing. By analysis of the atomically-resolved STM topographies, several kinds of dislocations have been observed and the corresponding geometric models are addressed. The armchair and zigzag phases both exhibited high stabilities for oxygen exposure. Conductance measurements imply that each phase interacts with the underlying layer. Our results might provide a way for fabricating stable ultrathin materials with a well-defined edge structure on oxide surfaces.

在金属氧化物层上制造的锑纳米结构对于太阳能电池，电子和光子设备领域的实际应用至关重要。在这里，对Cu（110）的氧化铜上的锑相进行了系统的研究。通过高分辨率扫描隧道显微镜（STM），我们发现无论初始氧化物结构如何，CuO表面都会形成起皱的锑相。如STM和密度泛函理论计算所证实的，它表现出由凸出和浸入的Sb原子组成的扶手椅状结构。进一步的Sb沉积导致扶手椅样相变形，随后导致形成ac（2×2）-Sb相。最后，成功制备了另一种起皱相。它由两条锯齿状的锑链组成，这些锑链的凸出和浸入的锑原子交替分布。通过分析原子解析的STM形貌，已观察到几种位错，并提出了相应的几何模型。扶手椅相和之字形相均显示出高的氧气暴露稳定性。电导率测量表明每个相都与下层相互作用。我们的结果可能提供一种在氧化物表面上制造具有明确边缘结构的稳定超薄材料的方法。电导率测量表明每个相都与下层相互作用。我们的结果可能提供一种在氧化物表面上制造具有明确边缘结构的稳定超薄材料的方法。电导率测量表明每个相都与下层相互作用。我们的结果可能提供一种在氧化物表面上制造具有明确边缘结构的稳定超薄材料的方法。
