Scientists working to identify materials that could one day replace silicon in faster computers may have found one. In the journal Advanced Functional Materials, a research team reports they have synthesized nanowires made from vanadium oxide and lead. And these nanowires perform a rare trick: when exposed to an applied voltage near room temperature, the wires transform from insulators that are resistant to carrying electricity to metals that more readily conduct electricity. Each of these two states—insulator and metal—could stand for a 0 or 1 in the binary code that computers use to encode information, or for the “on” and “off” states that the machines use to make calculations.
