Wood-derived substrate for microwave transistors

Fast flexible thin-film silicon electronics can be assembled on a wood-based substrate, claim researchers from the University of Wisconsin-Madison. The transparent flexible biodegradable substrate is cellulose nanofibrillated fibre (CNF). The team has to go to quite an effort to make its chip biodegradable: double gate transistors are formed in the top 270nm layer of a Soitech...
