The first transistor was about half an inch ... but when an electric signal traveled in through the gold foil, it injected holes (the opposite of electrons) into the surface.

When we were in school, every description of how transistors work was pretty ... if you want some help explaining electron and hole motion through semiconductors. One thing we were pleased to ...

transistor technology for gigascale digital systems. Examples of these innovations include mechanically strained silicon channels, where strain enhances electron and hole mobility, as well as gate ...
