Si(111)-(7X7surface reconstructionSTMdiffusionnucleationislandscoalescencegrowthHeteroepitaxial growth of Ag on Si(111)-(7X7) surface at various conditions was experimentally studied by scanning tunneling microscopy. A growth model based on experiments was used for kinetic Monte Carlo (KMC) simulations. ...
道电镜(STM)实验则在人类历史上首次观察到Si(111)一7x7表面的实空间形貌, 即每个表面单胞中有十二个凸起的亮包且在菱形表面单胞的四个顶角上有顶角 空缺(comerhole)存在,从而给出了包含有吸附原子及顶角空缺的DAS一模型的 具体实证。 1.1.1单晶Si(111)一7x7表面的几何结构 ...

The chemisorption of tetracene on the Si(111)-7x7 surface was studied using scanning tunneling microscopy (STM) and density functional theory (DFT) calculations. On the basis of the STM results and dimension analysis, two types of binding configurations were proposed. One of the configurations in...
Initial growth of silver on Ge(111) studied by scanning tunneling microscopy Scanning tunneling microscopy (STM) has been used to study the Ge(111) surface after submonolayer depositions of Ag. At the lowest coverages a (4×4) recon... M Hammar,G?thelid, M.,UO Karlsson,... - 《Phys...
XHnXN,P,O和S分子对Si1117×7表面化学修饰的理论研究
We have systematically investigated Na adsorption on the Si(111)-(7x7) surface at room temperature using scanning tunneling microscopy (STM). Below the critical coverage of 0.08 monolayer, we find intriguing contrast modulation instead of localized Na adsorbates, coupled with streaky noise in the STM...
