Solid State Physics for Engineering Students (PH319)
This course gives an introduction into classical and quantum mechanical aspects of solid state physics. Topics include crystal lattices, x-ray diffraction, concepts of quantum physics, the Schrodinger equation, electron tunneling, periodic potentials, an intro to the band structure theory, semiconductors and superconductors. Basic structural and electronic properties will be discussed, quantum approaches will be explained. Concepts such as electrons and holes, effective masses and carrier mobilities will be discussed in detail.
Electron Optics (PH410/610)
A survey on the behavior of charged particles in electron-optical devices is given. The course starts with a review of light optics and proceeds to the analogous optics of charged particles. Using analytical techniques, we will discuss electron lenses and develop the first-order focusing properties of multi-aperture lenses. Electron (and ion) trajectories will be calculated using SIMION, a numerical software package to visualize particle trajectories. Lens and image aberrations and their correction in electron microscopes will be discussed. Hands-on sessions in our microscopy lab will demonstrate how focal distances and lens aberrations can be measured. If time allows, there will be demos on our Photoemission Electron Microscope (PEEM).
Alternative Energies (PH473/573)
In modern societies energy production has been a key to productivity, wealth and progress. However, as technology spreads around the globe, it noticeably begins to affect the environment. Climate, limited resources and biodiversity seem to be in conflict with conventional energy schemes. Alternative energies may offer a safer path into the future. In this course the underlying physical principles of solar, wind, tidal and other alternative energies will be explained. The advantages of a decentralized technical approach will be pointed out, and realistic scenarios for a transition from the status quo towards more sustainable energy generation will be discussed. The emphasis in this course is on basic physical and technical ideas and concepts. Some economic issues will be discussed using insights and tools the from physics field.
