Prize share: 1/4
Work
Semiconductors, materials with properties between those of electrical conductors and insulators, are the basis for most electronic components. Some components use heterostructures, in which semiconductor materials lie in thin sheets. In 1957 Herbert Kroemer developed a proposal for a transistor built on heterostructures, and in 1963, at the same time as but independently of Zhores Alferov, Kroemer also built a heterostructure that acted as a laser. These components have since become important in telecommunications, for example.
Nobel Prizes and laureates
Six prizes were awarded for achievements that have conferred the greatest benefit to humankind. The 12 laureates' work and discoveries range from proteins' structures and machine learning to fighting for a world free of nuclear weapons.
