Computer Chips Made of Wood Promise Greener Electronics

alphadogg writes: Researchers in the U.S. and China have developed semiconductor chips that are almost entirely made out of a wood-derived material. In addition to being biodegradable, the cost of production is much less than conventional semiconductors. According to the NetworkWorld report: "The researchers used a cellulose material for the substrate of the chip, which is the part that supports the active semiconductor layer. Taken from cellulose, a naturally abundant substance used to make paper, cellulose nanofibril (CNF) is a flexible, transparent and sturdy material with suitable electrical properties. That makes CNF better than alternative chip designs using natural materials such as paper and silk, they argue in a paper published in the journal Nature Communications."
