The W-atoms were prepared on single crystalline MgO (001) films at 300°C by vacuum-deposition of WO3 or W-metal. Analysis of recorded images revealed individual jump-process of the W-atoms in the substrate temperature from R.T. to 400°C, and gave the barrier potential (Ed) and the pre-exponential factor (D0). Details of the microscopy and the data-analysis method are described as advanced techniques of HREM. © 1996 Oxford University Press Articles nationallicence time-resolved HREM nationallicence surface-diffusion nationallicence tungsten atoms nationallicence MgO (001) surfaces nationallicence activation barrier potential nationallicence Tanaka Nobuo Department of Applied Physics, School of Engineering, Nagoya University, Furō-chō, Chikusa-ku, Nagoya 464-01, Japan aut Kimata Hideaki Department of Applied Physics, School of Engineering, Nagoya University, Furō-chō, Chikusa-ku, Nagoya 464-01, Japan aut Kizuka Tokushi Department of Applied Physics, School of Engineering, Nagoya University, Furō-chō, Chikusa-ku, Nagoya 464-01, Japan aut Microscopy Oxford University Press 45/1(1996-02), 113-118 0022-0744 45:1<113 1996 45 jmicro https://doi.org/10.1093/oxfordjournals.jmicro.a023406 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/oxfordjournals.jmicro.a023406 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Tanaka Nobuo Department of Applied Physics, School of Engineering, Nagoya University, Furō-chō, Chikusa-ku, Nagoya 464-01, Japan aut NATIONALLICENCE 700 1- Kimata Hideaki Department of Applied Physics, School of Engineering, Nagoya University, Furō-chō, Chikusa-ku, Nagoya 464-01, Japan aut NATIONALLICENCE 700 1- Kizuka Tokushi Department of Applied Physics, School of Engineering, Nagoya University, Furō-chō, Chikusa-ku, Nagoya 464-01, Japan aut NATIONALLICENCE 773 0- Microscopy Oxford University Press 45/1(1996-02), 113-118 0022-0744 45:1<113 1996 45 jmicro Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
