在扫描探针显微镜(SPM)技术(包括原子力显微镜(AFM)、扫描隧道显微镜(STM)以及开尔文力探针显微镜(KPFM)等)中,探针针尖的状态和种类对于研究材料表面的物理、化学性质有着重要的影响.本论文以Cu(110)-O为例,主要研究利用AFM针尖控制技术对Cu(110)-O的不同相位,表面扫描结果及相位形成原因,Cu,O原子的关系以及针尖与表面原子种类识别的形成原因等.针对探针针尖原子种类以及尖锐程度的不同,证实了O原子针尖以及Cu原子针尖作用下对Cu(110)-O表面的Cu,O原子具有化学识别的功能.同时,研究发现针尖状态对材料表面信息识别具有重要影响,并给出了具体的解释和讨论.本研究对AFM表面原子成像、原子种类化学识别具有重要意义.
The state and type of probe tip in scanning probe microscopy (SPM) techniques, including atomic force microscopy (AFM), scanning tunneling microscopy (STM), and Kelvin stress probe microscopy (KPFM) The main content of this dissertation is Cu (110) -O. In this paper, the phase, surface scanning and phase formation of Cu (110) -O were investigated by using AFM tip control technique. The effects of Cu, O atom And the reasons for the formation of needle-like atoms and surface atoms, etc.According to the different types and sharpness of probe-tip atoms, it is confirmed that the Cu atoms and O atoms on the surface of Cu (110) -O have the Chemical recognition.At the same time, it is found that the tip state has an important influence on the material surface information identification and gives a specific explanation and discussion.This study is of great significance for AFM surface atomic imaging, atomic species chemical recognition.
