Microelectronics and Photonics

In this course, quantum mechanical concepts are applied to practical problems in physics, electronics, chemistry, and electrical engineering. The goal of this course is to develop the quantum mechanical foundation for modern electronic devices (MEMS, lasers, transistors, LEDs, quantum size effects in FETs, optical communication, etc.).

Develop a basis for understanding the quantum mechanical aspects
of modern electronics (lasers, quantized Hall effect, field effect transistors, optical tweezers, etc.)

- time-independent Schrodinger equation
- quantum mechanical tunneling
- bound states and scattering
- transmission electron microscopy
- the energy spectrum of diatomic and aromatic molecules
- the band structure of one-dimensional crystalline and disordered solids
- the scattering time for electron transport in a crystal
- the quantized Hall effect in a two-dimensional electron gas
- perturbation theory and field quantization
- two-state lasers
- light pressure forces on atoms
- quantization of LC circuits
- Casimir forces

Engineering Science: 3 credits

The objective of this course is introduce the quantum mechanical concepts needed to understand the operation of not only current nanoelectronic and nanophotonic devices and materials, but to understand the operating principles behind devices and materials still in their infancy. To this end, we will apply the principles of quantum mechanics to understand cutting edge next generation nanoelectronic devices and materials. This course combines the use of course textbooks with current literature to show how quantum principles are used not simply to understand traditional physics applications but to understand new physical effects and their potential applications in transformative new technologies.
