  1. Controlled manipulation of singleatoms and small molecules using thescanning tunnelling microscope Karina Morgenstern , Nicolas Lorente,and Karl-Heinz Rieder 小组成员:袁伟,芦宏,魏祎雯,赵欣欣,张成龙,王磊,蔡超逸,汪知昌 Phys. Status Solidi B, 1–81 (2013)/DOI 10.1002/pssb.201248392

  2. Advantages of STM: 1. real-space atomic resolution imaging 2.Electronic structure (local density of electronic states ) 3.Investigate physical/chemical properties at atomic level 4.Atomic and molecular manipulation

  3. 1. Introduction: Schematic view of an STM

  4. STM work principle

  5. Elastic tunneling Inelastic tunneling

  6. Manipulation: three different parameters formodifications of surfaces: forces between tip and surface (ii) electrical fieldbetween tip and substrate (iii) electron tunnelling current.

  7. Lateralmanipulation:

  8. Vertical manipulation:

  9. Manipulation employing the electron current

  10. Molecule chemistry with the STM Diffusion and desorption:
