Course description: The dimension of semiconductor devices is continuously shrinking to prolong Moore's law. In the foreseeable future, quantum phenomena will become more and more profound, which may seriously affect the characteristics of future electronic devices and impede the further downsizing. Development of novel semiconductor materials such as two-dimensional (2D) materials may resolve this problem. Thus, understanding the physics in such low-dimensional materials and systems is demanded. In this course, we will introduce several fundamental topics in low-dimensional material and systems, including nanowires and 2D materials. First, we will briefly review the quantum mechanics and apply these principles to develop the basic concepts of solid state physics, including band theory and charge transport properties in metals and semiconductors. Then, in terms of these knowledge, we will discuss electrical transport properties in low-dimensional electron systems such as quasi-1D nanostructures and 2D materials. Finally, we will learn the low-frequency (1/f) noise properties in metallic nanowires and 2D semiconductors. Objectives of this course: Students will learn several fundamental topics in low-dimensional electronic devices, including electrical transport properties in quasi-1D nanostructures and 2D materials, and the low-frequency (1/f) noise properties in metallic nanowires and 2D semiconductors.
