Thoughts on a new class named "The Physics of Modern Information Technology"

Currently, I am thinking about a new (elective) class on the physics of modern information technology for both B.Sc. and M.Sc. students that I would like to teach in the near future.  

Technically, this idea isn't entirely new, since, for example, there exists a book and a related class at the Massachusetts Institute of Technology (MIT) by Professor Neil Gershenfeld. However, the concept of my own proposed course is quite a bit different with a stronger focus on magnetic recording and spintronics, new devices in information technology (e.g., resistive random access memories and phase change memories) and alternative computing architectures (i.e., non-von Neumann computers based on neuromorphic computing, probabilistic computing, etc.). I also like the concept of the "Information Storage and Spintronics" class taught by Professor Atsufumi Hirohata at the University of York.

I hope that this is going to be a good blend of exciting modern condensed matter physics topics as well as applications in information technology. Let's see if I will be able to teach this class during the upcoming semesters. There is not much more to say about it right now, except for the syllabus that I would also like to share here (note that this is still work in progress though -- but please feel free to share your thoughts): 

  1. Basic principles of computation and information storage; information and noise; electromagnetic fields and waves; antennas
  2. Semiconductor materials and devices; transistors, MOSFETs, integrated circuits, manufacturing, logic gates, processors, recent developments and future applications
  3. Optical materials and devices; LEDs, lasers, displays, optical fibers, communication, photonics
  4. Magnetic tape storage and hard disk drives; magnetism 101, materials, write and read heads, longitudinal and perpendicular recording
  5. Advanced magnetic recording; HAMR, bit-patterned media, shingled magnetic recording, helium drives
  6. Magnetic-random access memory; STT-MRAM, SOT-MRAM
  7. Promising non-volatile memory solutions; racetrack memory and skyrmions, ferroelectric memory, phase change memory, RRAMs, DNA for information storage
  8. Magnonics; magnonic crystals, spin-wave based computing
  9. Alternative computing systems and architectures; neuromorphic computing, STNOs, probabilistic computing, p-bits
  10. Quantum computing and communication
  11. Other hot topics in information technology; impacts on society; information technology in Germany and the rest of the world
