Biography of Famous Scientist Walter Schottky
Walter Schottky: Pioneer in Semiconductor Physics and Electronics
Early Life and Education:
Walter Hans Schottky was born on July 23, 1886, in Zurich, Switzerland. He came from a family with a strong academic background. Schottky studied physics at the University of Berlin, where he earned his doctorate in 1912 under the supervision of Max Planck. During his early academic years, he developed a keen interest in experimental physics and electronic phenomena.
World War I Service:
With the outbreak of World War I, Schottky served in the German military. After the war, he resumed his scientific pursuits, focusing on the emerging field of solid-state physics.
Contributions to Semiconductor Physics:
Schottky made significant contributions to the understanding of the behavior of electrons in solids, particularly in semiconductors. In 1919, he proposed the existence of a barrier at the metal-semiconductor interface, which came to be known as the Schottky barrier. This concept played a crucial role in the development of semiconductor devices.
Academic Positions and Collaborations:
Throughout his career, Schottky held various academic positions. He worked at the Siemens Research Laboratory and the Physikalisch-Technische Reichsanstalt (PTR) in Berlin. He also collaborated with other notable physicists of his time, including Werner Heisenberg and Max von Laue.
Research on Electron Emission:
In the 1920s, Schottky conducted extensive research on electron emission phenomena, contributing to the understanding of thermionic emission and the development of vacuum tubes. His work in this area laid the foundation for advancements in electronic devices and communication technology.
Later Career and World War II:
During the 1930s, Schottky continued his research in semiconductor physics. However, due to political reasons and the rise of the Nazi regime, he faced challenges in his career. Schottky left Germany in 1934 and moved to Switzerland, where he continued his research.
Post-World War II Period:
After World War II, Schottky’s contributions to semiconductor physics gained broader recognition. He returned to Germany and held academic positions at the Technical University of Munich. His work laid the groundwork for the development of semiconductor devices crucial to the electronics industry.
Awards and Honors:
In recognition of his significant contributions, Walter Schottky received several awards and honors. Notably, he was awarded the Max Planck Medal in 1956 for his achievements in theoretical physics.
Legacy:
Walter Schottky’s work had a profound impact on the field of semiconductor physics and electronics. The Schottky barrier and the Schottky diode are named after him. His insights into electron behavior in semiconductors paved the way for the development of modern electronic devices and solid-state technology.
Walter Hans Schottky passed away on March 4, 1976, leaving behind a lasting legacy in the world of physics and technology. His pioneering contributions continue to influence the advancement of semiconductor research and applications in the contemporary era.
