Research Interests and achievement |
Updated on September 3, 2006
My research interests focus on two branches of condensed matter physics. One is the interaction of adsorbed atoms or molecules on surfaces. The other one is the fabrication and characterization of nanostructures. The tools used in the investigations are variable-temperature STM and AFM. The very early stage of reaction of condensed matter occurs on the surface. Therefore, the interaction between surface and atoms or molecules is fundamental to the reaction followed. The beginning reaction of the foreign atom or molecule with the surface is adsorption. Intermediated by the surface, the interaction between adsorbed particles becomes more complex than that when they are in gaseous state. This interaction plays key role not only in the growth of thin films and the property of the adsorbate structures but also in the design of functional materials and sensors. On the other hand, nanostructures possess special properties due to their nanometer size, and thus attract intense attention in applications and fundamental researches. The nano vogue is mainly triggered after the inventions of STM and AFM due to their capability in fabrication, characterization, and observation of atomic structures. In presence, I am interested in the nanostructures on silicon wafers by using STM and AFM. Basically, the property of nanometer-size area can be altered physically, chemically, or mechanically by the probe of STM or AFM, and followed by physical or chemical processing, the nanostructure is made from the nanometer-size area.
