This course is closely linked with the following four courses: Semiconductor Materials and Devices, Introduction of Photovoltaic and Photothermal Technique, Corrosion and Protection of Materials, and Materials Processing Technology. It is the supplement of these theoretical courses. In this course, students will conduct: 1) tests of the parameters about semiconductor materials and devices, 2) experiments about the electric, optical, magnetic properties of different materials, 3) experiments about the corrosion and protection of materials, d) environmental testing, 4) 3D printing techniques. After finishing this course, students can better master the knowledge about the various properties of materials and understand how to use these properties in the daily life. Meanwhile, their abilities to think independently, problem solve and innovate will greatly improve.
