The instructor lectures widely on the structure, properties, evaluation methods, applications, etc. for solid surfaces. The course focuses on inorganic materials, but surface properties of various solids such as metals, organic matter, ionic crystals, covalent crystals, semiconductors, amorphous materials, etc. are also touched on. By explaining through comparison, students acquire knowledge related to selecting processes and materials, as well as basic thought for creating the desired solid surface properties. Students are also introduced as best as possible to the newest topics related to technology for surface treatment and surface evaluation. This course thus does not consist of simply bestowing knowledge, but of graduate level surface chemistry.
The surface of solids is the direct interface between that material and other substances, light, electrons, heat, forces, magnetism, etc. By effectively controlling this "field", it is possible to extract the properties of bulk solids, and bestow the surface with properties that differ from bulk solids. The course focuses on content conducive to designing such surface function materials, in particular their structure and composition. Students will gain an understanding of basic approaches for controlling surface properties.
By the end of this course, students will be able to :
1) Understand fundamentals of surface science on inorganic solids.
2) Acquire the knowledge on the technologies on surface control and its evaluation.
3) Apply the fundamental knowledge on surface chemistry to the design of various surface functional materials.
