通过角分辨光电发射研究了 Pt(997) 表面上生长的单原子 Cu 链阵列的电子结构。单原子线表现出与一维 3d 电子限制相关的特性。沿着导线方向，3d 能带状态显示出色散特征，具有由导线阵列几何形状定义的倒易空间中的周期性。这些观测结果通过基于全势线性化增强平面波方法的从头计算进行了比较和分析。
The electronic structure of an array of monatomic Cu chains grown on the Pt(997) surface has been examined by angle-resolved photoemission. The monatomic wires exhibit properties associated with 3d electron confinement in one dimension. Along the wire direction, the 3d bands states display a dispersive character, with periodicity in reciprocal space defined by the wire array geometry. These observations are compared and analyzed with ab initio calculations based on the full-potential linearized augmented plane-wave method.
