Shockley worked out a rather complete description of what he called the "sandwich" transistor, and a first proof of principle was obtained on April 7, 1949. Meanwhile, Shockley worked on …

On January 23, unable to sleep, Shockley was sitting at the kitchen table bright and early in the morning. He suddenly had a revelation. Building on the "sandwich" device he'd come up with …

After Bardeen and Brattain's December 1947 invention of the point-contact transistor (1947 Milestone), Bell Labs physicist William Shockley began a month of intense theoretical activity.

William Bradford Shockley was head of the solid-state physics team at Bell Labs that developed the first point-contact transistor, which he quickly followed up with the invention of the more …

Jan 9, 2025 · One month after Shockley perfected his theoretical design, Bell Labs filed four patents for semiconductor amplifiers – both Brattain and Bardeen’s original point contact …

Abstract: The failure in 1945 of experiments proposed by Shockley, on what today would be called thin-film field-effect transistors, was a creative failure that stimulated Bardeen in early 1946 to …

The grown-junction transistor was the first type of bipolar junction transistor made. [1] It was invented by William Shockley at Bell Labs on June 23, 1948 [ 2 ] (patent filed June 26, 1948), …

May 27, 2021 · One of the great ironies of transistor history is that Shockley’s junction transistor was not the field effect device he had envisioned in 1945, but rather the modern bipolar …

Mar 9, 2015 · William Shockley tells how he and his associates conceived and developed the junction transistor for which he, J. Bardeen and W. Brattain, were awarded a Nobel Prize in …

The brilliant revolutionary conception of the junction transistor by Shockley, as shown in Fig. 2, first appeared in a patent application filed on June 26, 1948 (Fig. 4), which was issued in …
