At elevated temperatures of 1000-1500 K, carbon (C) atoms that segregated to a surface and mixed with the boron (B) honeycomb lattice resulted in the formation of three different BC(x) layers as the topmost layers of NbB(2)(0001). Two of the layers were commensurate lattices: √7 × √7 and √3 × √3 structures; the third was incommensurate. The characteristic features of the √3 × √3 lattice with a honeycomb structure are discussed on the basis of the experimental data.
在 1000-1500 K 的高温下，分离到表面并与硼（B）蜂窝晶格混合的碳原子（C）导致在 NbB(2)(0001)的最顶层形成了三种不同的 BC(x)层。其中两层是共格晶格：√7×√7 和 √3×√3 结构；第三个是不相称的。基于实验数据，讨论了具有蜂窝结构的 √3×√3 晶格的特征。
