Michael Kneissl

Michael Kneissl is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Michael Kneissl rather than just read about it. In short: Michael Kneissl is a German physicist and professor at the Institute of Solid State Physics at Technische Universität Berlin. Kneissl received his doctoral degree in physics from the Friedrich-Alexander University of Erlangen–Nuremberg in 1996.

Key takeaways

Michael Kneissl belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Michael Kneissl to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Michael Kneissl from memory before moving on to harder problems.

Reference excerpt

Michael Kneissl is a German physicist and professor at the Institute of Solid State Physics at Technische Universität Berlin. Kneissl received his doctoral degree in physics from the Friedrich-Alexander University of Erlangen–Nuremberg in 1996. During his graduate studies, he was a visiting scholar at the University of California, Berkeley, in 1993. He joined the Xerox Palo Alto Research Center (PARC) in 1996. Since 2005, he has been a Full Professor and the Chair of Experimental Nanophysics & Photonics at the TU Berlin. He holds a joint appointment at the Ferdinand-Braun-Institut in Berlin, where he heads the Joint Lab GaN-Optoelectronics. Excluding a two-year hiatus in 2021 he has served as the Executive Director of the Institute of Solid State Physics at TU Berlin from 2011 to 2025. Since 2021 Kneissl is the Chairman of the Executive Board of the Advanced UV for Life e.V. association and since 2024 spokesperson for the newly established Center for Integrated Photonics Research (CIPHOR) at TU Berlin. His research interests include group III-nitride semiconductor materials, metalorganic vapour-phase epitaxy of wide-bandgap semiconductors and (In)AlGaN nanostructures as well as novel optoelectronic devices, including UV LEDs and laser diodes. He was named Fellow of the Institute of Electrical and Electronics Engineers (IEEE) in 2016 for contributions to the development of wide bandgap semiconductor laser diodes and ultraviolet LEDs. He holds more than 60 patents in the area of group III-nitride device technologies.

Worked examples

Example 1 — a first encounter with Michael Kneissl

Start with the simplest possible case. Write down what Michael Kneissl claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Michael Kneissl before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Michael Kneissl ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Michael Kneissl

In research: Michael Kneissl appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Michael Kneissl in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Michael Kneissl is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1966 births, Academic staff of Technische Universität Berlin, Fellows of the IEEE, so understanding it makes those chapters shorter.
In everyday life: Look for Michael Kneissl outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
