Walter Houser Brattain Biography
Walter Brattain was Houset United States physicist. Together with William Shockley and John Bardeen he discovered the transistor in 1947. Nine years later (1956), the three physicists received the Nobel prize for physics because they find researching semiconductor transistors. The three men are scientists who worked on the Bell Telephone laboratories.
Brattain was born in Amoi, China on February 10, 1902. At age 22 he graduated from Whitman College, Walla-Walla, Washington. Two years later he graduated from the University of Oregon. At 27 years he graduated from the University of Minnesota. Over the past 38 years (1929-1967), he worked as a research physicist at Bell Telephone laboratories. In this place Brattain served studying semi-conductors.
Kondukor example is a metal, semiconductor samples are silicon and germanium. Brattain has always worked with William Shockley and John Bardeen. In 1947 (other sources say 1948), three were found transistor (transfer resistor). The transistor is a tool to strengthen, organize and generate electrical signals. The transistors are widely used in radio, television, computers, rockets and satellites. Sebelum1950, radios using vacuum tubes, after years tersebutorang prefer to use a transistor because it is lighter, smaller, more durable, more resistant to heat, more efficient, more energy efficient than vacuum tubes. The discovery opens a new page of history transistor electronics.
