Stefan Hüfner

Stefan Hüfner is a astronomy 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 Stefan Hüfner rather than just read about it. In short: Stefan Hüfner (July 2, 1935, in Löwenberg, Silesia – January 17, 2013, in Saarbrücken, Saarland) was a German experimental physicist specialized in solid-state physics and photoemission spectroscopy. Education and career Hüfner studied mathematics and physics at the Goethe University of Frankfurt and the Technical University of Darmstadt.

Key takeaways

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

Reference excerpt

Stefan Hüfner (July 2, 1935, in Löwenberg, Silesia – January 17, 2013, in Saarbrücken, Saarland) was a German experimental physicist specialized in solid-state physics and photoemission spectroscopy.

Education and career Hüfner studied mathematics and physics at the Goethe University of Frankfurt and the Technical University of Darmstadt. After graduating from 1960 to 1966, he was a scientific assistant at the Institute for Technical Physics at the TU Darmstadt. In 1963 he received his doctorate there, supervised by Karl-Heinz Hellwege. In 1966 he obtained habilitation in physics. He was a guest researcher at the Technical University of Munich and at the Bell Telephone Laboratories in Murray Hill, New Jersey, USA. From 1967 to 1968 he was a privatdozent at the TU Darmstadt and the doctoral supervisor of Peter Grünberg, who was awarded the Nobel Prize in Physics in 2007. In 1968 he received a call to the professorship for experimental physics at the Free University of Berlin as the successor to Professor Gerhard Simonsohn. In 1975, Hüfner moved to the professorship for experimental physics at Saarland University. In 1994 he became founding speaker of the Collaborative Research Center "Interface-determined Materials". In 2001 he took over the office of university vice president for planning and strategy, which he held until the beginning of 2003. In September 2003 he retired.

Honors and awards

Hüfner was an emeritus member of the advisory board of the Max Planck Institute for Nuclear Physics in Heidelberg, the Max Planck Institute for Physics in Munich, the Max Planck Institute for Plasma Physics in Greifswald and Munich and the Max Planck Institute for Quantum Optics in Munich and other advisory boards of the Max Planck Society. Since 2004 he has been a member and chairman of the Technical Committee for Engineering Sciences of the Elite Network of Bavaria. In 2006/2007 he was a visiting professor at the University of British Columbia in Vancouver, Canada. He received honorary doctorates from the University of Fribourg and the Free University of Berlin.

Works Hüfner authored the classic textbook on photoemission spectroscopy, first published in 1995 and has gone through three editions in total. In addition to numerous scientific publications, Hüfner has also written several novels, including Der Tote von Dresden (Conte Verlag 2004, ISBN 978-3-936950-49-6) and Artikel eins. Ein Zukunftsroman (Conte Verlag 2006, ISBN 978-3-936950-41-0).

Worked examples

Example 1 — a first encounter with Stefan Hüfner

Start with the simplest possible case. Write down what Stefan Hüfner claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Stefan Hüfner 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 Stefan Hüfner 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 Stefan Hüfner

In research
Stefan Hüfner appears in astronomy 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 Stefan Hüfner 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
Stefan Hüfner is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1935 births, 2013 deaths, 20th-century German physicists, so understanding it makes those chapters shorter.
In everyday life
Look for Stefan Hüfner 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.
