| Outline and Purpose of the Course | As the foundation for solid-state electronic engineering and semiconductor engineering to be taken by third-year students, detailed discussion is made of the theory of operations of various types of optical and electronic devices. Detailed explanation begins with the fundamentals of operations theory in optical devices. | |||
| Course Goals | Students will understand the physical background of spontaneous emission processes, as well as various elements essential when considering spontaneous emission processes in semiconductors. | |||
| Schedule and Contents |
Basic light emission processes (4-5 classes) An overview is made of spontaneous emission processes in two-level electron systems. Explanation is then made of Fermi’s golden rule, electric dipole interactions, density of light (photon) states, etc. Finally, theoretical expression of the light-emitting relaxation rate is derived. Light emission processes from semiconductors (4-5 classes) An overview is presented of the processes from energy input to a semiconductor, to light emission. Next, the physics of light-emitting devices are explained. Using electron-hole state density and distribution functions, etc., theoretical formulas of emission spectra in the steady state are derived. Rate equations describing the transient state are also derived, with explanation of the elements that determine luminous efficiency. Control of electron state and emission characteristics (4-5 classes) Light-emission characteristics can be controlled via control of the electron states of a semiconductor light-emitting device. Explanation especially focuses on methods of improving emission characteristics by using quantum structure. Various quantum structures using semiconductor heterostructure are discussed. Explanation is also made of methods of calculating quantization level and of electron devices that use quantum structure. Confirmation of extent of student learning (1 class) Confirmation is made of the extent of student learning. |
