| 中文摘要 | By precise control of substrate temperature, two kinds of structures (structure I and structure II) of coronene on Ag(110) are alternatingly observed by in situ molecular beam epitaxy-low energy electron diffraction. This series of alternating structural transition is confirmed by scanning tunneling microscopy images and density functional theory calculations. As the substrate temperature increases after the molecular monolayer growth at 250 K, the first transition from structure I to structure II occurs around 335 K, which is due to the different vibrational contributions of structures I and II to their free energy. The second transition from structure It to structure I around 367 K is due to the molecule-molecule repulsion, at that temperature the molecular island dissociation and the molecular desorption are dramatically activated and thus the molecule-molecule interaction becomes the dominant effect to the molecular structure. Comprehension of the underlying physics processes behind this alternating structural transition helps establish an understanding of the structural evolution and thermal stability of functional molecular thin films. |
