NANO4311 — Physical Principles of Nanoscience
This course introduces the physical principles of nanoscience to the students. The course aims at an introduction to basic principles of nanophysics allowing working in research and development in nanotechnology. Students will learn basic principle of physics of nanometer-size systems with a focus on basic physical phenomena including an introduction to quantum mechanics and nanoelectronics. Wave mechanics, the Schröedinger equation, free and confined electrons, band theory of solids. Nanosolids in 0D, 1D, and 2D. Nanowires, quantum dots, thin films, electrical transport, and optical behavior. In addition to elucidating the basic theoretical concepts, main application to existing and future electronics, optoelectronics and quantum computing will be discussed. The broadest purpose of the course includes the following: To identify the classical physics challenges that initiated quantum mechanics Write and explain the de Broglie relationship Write and explain Schrodinger equation Write the state function for different potential wells Explain the effective mass concept Derive the density of states for quantum dots, wires, and wells. Identify the direct and indirect bandgap materials and their properties Explain the exitons in bulk and quantum dots/wells. Explain how photoluminescence occurs Differentiate the drift and diffusion currents Exemplify different electronic nanostructure devices Exemplify different optoelectronic nanostructure devices
