Purdue University researchers are making progress in developing a new type of transistor that uses a finlike structure instead of the conventional flat design, possibly enabling engineers to create faster and more compact circuits and computer chips.
The fins are made not of silicon, like conventional transistors, but from a material called indium-gallium-arsenide. Called finFETs, for [...]
