Can someone please account for the discrepancy between the first statement in the article and and the entry from from Wikipedia?

"The first three patents for the field-effect transistor principle were registered in Germany in 1928 by physicist Julius Edgar Lilienfeld, but Lilienfeld published no research articles about his devices, and they were ignored by industry. In 1934 German physicist Dr. Oskar Heil patented another field-effect transistor. There is no direct evidence that these devices were built, but later work in the 1990s show that one of Lilienfeld's designs worked as described and gave substantial gain. Legal papers from the Bell Labs patent show that Shockley and Pearson had built operational versions from Lilienfeld's patents, yet they never referenced this work in any of their later research papers or historical articles.

I've done the best I can to describe how an FET works. However, it's pretty difficult without a diagram! It will be even harder with BJTs without being able to point to an energy band diagram. PMorgan 10:51, 22 March 2009 (EDT)

You can look for a diagram or image to be uploaded, as long as it is within the bounds of fair use. A good place to look is here. You can then submit your image upload request here so an administrator can get that for you. WesleySHello! 10:55, 22 March 2009 (EDT)
