利用光电子能谱、原子力显微镜以及低能电子衍射等 表面研究手段系统研究了真空沉积生长的酞菁铜薄膜与衬底MoS2（0001）之间的范德瓦耳斯异质结界面电子结构和几何结构. 角分辨光电子能谱清楚地再现了MoS2（0001）衬底在Γ点附近的能带结构. 低能电子衍射结果表明，CuPc薄膜在MoS2（0001）表面沿着衬底表面[1120]，[1210]和[2110]三个晶向有序生长，反映了衬底对CuPc的影响. 原子力显微镜结果表明，CuPc在MoS2 衬底上遵循层状-岛状生长模式：在低生长厚度下（单层薄膜厚度约为0.3 nm），CuPc分子平面平行于MoS2表面上形成均匀连续的薄膜; 在较高的沉积厚度下，CuPc沿衬底晶向形成棒状晶粒，表现出明显的各向异性. 光电子能谱显示界面偶极层为0.07 eV，而且能谱在膜厚1.2 nm饱和，揭示了酞菁铜与MoS2（0001）范德瓦耳斯异质结的能级结构.
