Study may lead to new electronic devices
U.S. researchers say they have developed a technique using a silicon crystal as a type of nanoscale vice to squeeze another crystal into a more useful shape.
The scientists led by Professor Darrell Schlom of Cornell University and Joseph Woicik of the National Institute of Standards and Technology said their accomplishment might lead to development of a new class of electronic devices that remember their last state even after power is turned off. Computers that could switch on instantly without
booting an operating system is one of the possibilities, the researchers said.
ferroelectriccompound that might serve as a fast, efficient medium for data storage.
The scientists also demonstrated the ability to write, read, store and erase patterned bits of data in the strontium titanate film.
Various aspects of the study that included researchers from the University of Pittsburgh, Pennsylvania State University, Northwestern University, Motorola, Ames Laboratory, the Intel Corp. and Tricorn Tech appeared in the April 17 issue of the journal Science and the April 24 issue of the journal Physical Review B.
