Researchers from Northwestern University in the US have developed a material that can radically change its electronic properties. A resistor made from it could become a transistor or a diode, according to the report in the journal Nature Nanotechnology. The discovery could lead to cheaper, smaller and more powerful computers. As electronics advance and demands for portability increase, one of the main challenges has been decreasing the size of elementary components. Technology firms have attempted to address this with a number of innovations, including new ways of building circuit tracks so signals do not suffer damaging interference at ultra small sizes.
