Nanowires may allow many more transistors to be placed on computer chips in the future

Engineers and researchers predict that in the next five to ten years the dimensions of silicon transistors will have been scaled to their limits and will be unable to get any smaller. Without a new breakthrough in creating smaller transistors, Moore's Law will fall flat.



A group of engineers and researchers working together from IBM, Purdue University, and the University of California at Los Angles has learned to create nanowires coated with materials that make for efficient transistors. The nanowires have very sharply defined layers at the atomic level that allow the wires to be efficient transistors.

Eric Stach, associate professor of materials Engineering from Purdue said, "Having sharply defined layers of materials enables you to improve and control the flow of electrons and to switch this flow on and off."

The team of researchers says that electronic devices are often constructed of heterostructures. The term heterostructures means that the structure contains sharply defined layers of different semiconducting materials like silicon and germanium. According to the researchers, the challenge in the past has been the capability of producing nanowires with the requisite defined layers. [More...] [Comments...]
