The American physicist Walter H. Brattain (), a co-inventor of the transistor, devoted much of his life to research on surface states. Although he was born in Amoy, China (February 10, ), Walter Houser Brattain spent the early part of his life in the northwest of the United States.

Brattain earned a bachelor's degree from Whitman College in , with a double major in physics and mathematics. John Workman were later known as "the four horsemen of physics" because all went on to distinguished careers.
His thesis, supervised by John T. His first wife was chemist Keren Gilmore.
They married in and had a son, William G. Keren Gilmore Brattain died April 10, Emma Jane Kirsch Miller, who already had three children, in He died on October 13, , in a nursing home in Seattle from Alzheimer's Disease. In August he joined Joseph A.
Becker at Bell Telephone Laboratories as a research physicist. They also did work on the surface state and work function of tungsten and the adsorption of thorium atoms. This work was considered by the Nobel prize committee to be one of his chief contributions to solid state physics.
Vacuum tubes were neither reliable nor efficient, and Bell Laboratories wanted to develop an alternative technology. Shockley on the idea of a semiconductor amplifier that used copper oxide, an early and unsuccessful attempt at creating a field effect transistor. Other researchers at Bell and elsewhere were also experimenting with semiconductors, using materials such as germanium and silicon , but the pre-war research effort was somewhat haphazard and lacked strong theoretical grounding.
Creation of the sub-department was authorized by the vice-president for research, Mervin Kelly. According to theories of the time, Shockley's field effect transistor, a cylinder coated thinly with silicon and mounted close to a metal plate, should have worked. He ordered Brattain and Bardeen to find out why it wouldn't. During November and December the two men carried out a variety of experiments, attempting to determine why Shockley's device wouldn't amplify.
Replacing silicon with germanium enhanced the amplification, but only for low frequency currents.

The gold contacts were pressed down on the bare surface. Both gold contacts to the surface rectified nicely One point was used as a grid and the other point as a plate.
The names emitter and collector were chosen to describe this phenomenon. The only question was how the charge of the added holes was compensated. Our first thought was that the charge was compensated by surface states. Shockley later suggested that the charge was compensated by electrons in the bulk and suggested the junction transistor geometry Later experiments carried out by Brattain and me showed that very likely both occur in the point-contact transistor.
Shockley demonstrated the first working transistor to their colleagues at Bell Laboratories. Amplifying small electrical signals and supporting the processing of digital information, the transistor is "the key enabler of modern electronics". Initially, strict secrecy was observed.
Walter H. Brattain
Carefully restricted internal conferences within Bell Labs shared information about the work of Brattain, Bardeen, Shockley and others who were engaged in related research. They also adopted an open policy in which new knowledge was freely shared with other institutions. By doing so, they avoided classification of the work as a military secret, and made possible widespread research and development of transistor technology.
Bell Laboratories organized several symposia, open to university, industry and military participants, which were attended by hundreds of scientists in September , April , and Representatives from international as well as domestic companies attended. He continued to study the surface properties of solids and the "transistor effect", so as to better understand the various factors underlying semiconductor behavior.
Walter Brattain is credited as having said, when told of the award, "I certainly appreciate the honor. It is a great satisfaction to have done something in life and to have been recognized for it in this way.
However, much of my good fortune comes from being in the right place, at the right time, and having the right sort of people to work with. Sawyer on several papers on electrochemical processes in living matter. He also collaborated with Whitman chemistry professor David Frasco , using phospholipid bilayers as a model to study the surface of living cells and their absorption processes. Upon formally retiring from Bell Laboratories in , he continued to teach at Whitman, becoming an adjunct professor in He retired from teaching in but continued to be a consultant at Whitman.
