Há 5 dias · The invention of the transistor in 1947 by John Bardeen and Walter Brattain marked a pivotal moment in semiconductor history. While the operational mechanics were initially unclear, John Shive's experiment in 1948 confirmed that the transistor's operation was based on bulk conduction, aligning with William Shockley's theory on p-n ...

Há 20 horas · Richard Phillips Feynman (/ ˈ f aɪ n m ə n /; May 11, 1918 – February 15, 1988) was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, as well as his work in particle physics for which he proposed the parton model.
Há 5 dias · For example, 1947 was the year the Hungarian-British electrical engineer and physicist Dennis Gabor invented holography. 1947 was also the year William Shockley, John Bardeen, and Walter Brattain demonstrated the first transistor at Bell Labs.
Há 5 dias · Two Bell Labs researchers, John Bardeen and Walter Brattain around Christmas of 1947, discovered this thing that they will eventually call the transistor. They know what they have. Bell Labs, AT&T, goes to get patents, and then they go public with this invention.
Há 4 dias · Jörg Schmalian was awarded the 2022 John Bardeen Prize. Momentum Dependence of Electron-Phonon Coupling Strong renormalization of the life time of lattice vibrations, i.e. phonons, can occur in the absence of both Fermi surface nesting and lattice anharmonicity if electron-phonon coupling is strongly enhanced for specific values of ...
