Schottky

Japanese: ショットキー

1883‐1976
A Swiss-born physicist who was active in Germany. He studied electron emission and rectification phenomena, and invented the shielded-grid tetrode vacuum tube, which provides stable high-frequency amplification. Born in Zurich, he studied under M. Planck at the University of Berlin. He served as a professor at the University of Rostock and directed the Siemens communications research laboratory. He studied electron emission from metals into vacuum, and published a theory of Schottky emission that takes into account image forces, and elucidated vacuum tube noise caused by non-uniformity in electron emission. He also studied contact between semiconductors and metals, and proposed the Schottky barrier theory and diffusion rectification theory around 1939.

スイス出身でドイツで活躍した物理学者。電子放出や整流現象を研究し，高周波増幅を安定に行える遮へい格子四極真空管を発明した。チューリヒに生まれ，ベルリン大学でM.プランクの下で学んだ。ロストク大学の教授をつとめ，ジーメンス社の通信研究所を指導した。金属から真空への電子放出を研究し，鏡像力を考慮したショットキー放出の理論を発表，そして，電子放出の不均一性による真空管の雑音について解明した。また，半導体と金属の接触を研究し，1939年ころにショットキーバリヤー理論や拡散整流理論を提唱した。
