Herbert Kroemer

Herbert Kroemer was born on August 25, 1928 in Weimar, Germany, German, is Physicist. Herbert Kroemer is an eminent German-American physicist who won the Nobel Prize in Physics in 2000 "for developing semiconductor heterostructures used in high-speed- and opto-electronics". He was brilliant as a child and quite disruptive at school. It was only because of his academic excellence that he evaded expulsion. After graduating from gymnasium he first entered University of Jena with physics. But because of the atmosphere there, he fled to West Germany and managed to get admission at University of Göttingen, from where he earned his PhD at the age of twenty-four. Subsequently, he began his career as a ‘House Theorists’ at the Central Telecommunications Laboratory (FTZ) of the German postal service, bur soon started experimenting on the frequency limitations of the new transistors, which led to his work on heterostructures. Later he worked at different places such as RCA Laboratories in New Jersey, Philips in Hamburg, Varian Associates in California, University of Colorado at Boulder, and University of California, Santa Barbara. At each place he carried on researches on different semiconductor topics. However, it was his work on the heterostructures, which earned him the Nobel Prize in Physics and paved the way for great technological development.

🌙 Zodiac

Herbert Kroemer’s zodiac sign is Virgo. According to astrologers, Virgos are always paying attention to the smallest details and their deep sense of humanity makes them one of the most careful signs of the zodiac. Their methodical approach to life ensures that nothing is left to chance, and although they are often tender, their heart might be closed for the outer world. This is a sign often misunderstood, not because they lack the ability to express, but because they won’t accept their feelings as valid, true, or even relevant when opposed to reason. The symbolism behind the name speaks well of their nature, born with a feeling they are experiencing everything for the first time.

🌙 Chinese Zodiac Signs

Herbert Kroemer was born in the Year of the Dragon. A powerful sign, those born under the Chinese Zodiac sign of the Dragon are energetic and warm-hearted, charismatic, lucky at love and egotistic. They’re natural born leaders, good at giving orders and doing what’s necessary to remain on top. Compatible with Monkey and Rat.

He worked in a number of research laboratories in Germany and the United States and taught electrical engineering at the University of Colorado from 1968 to 1976. He joined the UCSB faculty in 1976, focusing its semiconductor research program on the emerging compound semiconductor Technology rather than on mainstream silicon Technology.


Along with Charles Kittel he co-authored the popular textbook Thermal Physics, first published in 1980, and still used today. He is also the author of the textbook Quantum Mechanics for Engineering, Materials Science and Applied Physics.


Kroemer was elected as a member of the National Academy of Engineering in 1997 and the National Academy of Sciences in 2003. He always preferred to work on problems that are ahead of mainstream Technology. In the 1950s, he invented the drift transistor and was the first to point out that advantages could be gained in various semiconductor devices by incorporating heterojunctions. Most notably, in 1963 he proposed the concept of the double-heterostructure laser, which is now a central concept in the field of semiconductor lasers. Kroemer became an early pioneer in molecular beam epitaxy, concentrating on applying the Technology to untried new materials.
