Short description of content: We make an overview of some recent topics concerning atomic and nuclear physics, as related to current and planned small tabletop experiments, as well as accelerator-based experiments. A simple overview of the theoretical background of the Standard Model related to these experiments are provided during the first 2/3 of the semester. In this semester, we will cover the fundamental symmetries, weak interaction, electroweak theory, and Higgs mechanism; with some discussion on WIMP dark matter in the context of small-scale atomic physics experiments. During the first few lectures, we will review the material covered in Modern atomic and nuclear physics I. The lecture assumes some basic undergraduate-level knowledge of quantum mechanics.

Until the coronavirus issues are resolved, the lectures will be provided online using Zoom. If you have questions, please e-mail: Masaki.Hori@mpq.mpg.de If you would like to participate, please register in LSF and you will receive the password to the Zoom session.

Note: I was told the "register" function in LSF doesn't seem to be available for exchange students. If this is true for you, please e-mail me and I will register you.

Content of the course:
Fundamental properties of semiconductors and semiconductor devices. Focus is on the introduction of relevant materials, in particular doped Si, GaAs heterostructures, organic semiconductors,  2D-materials, and lead halide perowskites. We introduce fundamental concepts to explain physical properties of these materials. This includes experimental characterization by electrical and optical methods and typical device applications. Most important topics are: Crystal lattice and band structures, optical and electronical excitations, charge separation and charge transport, transistors, photo diodes and photovoltaics, LEDs and laser diodes
