【This course will be held in English in the presence of an IGP student.】This course covers atomic structure and electronic state at solid surfaces, and atomic dynamics, incorporating experimental data. Starting with the basics of crystallography, students are shown how atomic structure at surfaces are represented, and how to measure it through the scattering and diffraction of electrons and light in experiments. Students are also shown how on the surface a unique electronic state different from that within the crystal exists, and we prove it by using the photoelectric effect and tunnel effect to measure it. We finally cover diffusion, absorption, and desorption phenomena at solid surfaces. Studying solid physics is a prerequisite, but we will review it as needed.
Students will learn that physical phenomena at solid surfaces differ from bulks, and learn the basics of physical property measurement techniques specific to surfaces.
As an introduction to surface science, this course covers physical phenomena of solid surfaces and the theory and calculation techniques for understanding them, as well as the methods for analyzing structure, electron state, and composition. We will also touch on topics of cutting-edge surface research, and experience how quantum mechanics, statistical mechanics, and solid physics influence surface research.
