【Summary description】 Scientists at Nagoya University in Japan have developed a nanowire using a new method.

Scientists at Nagoya University in Japan have developed a nanowire using a new method. According to the scientists, the new method is much simpler than previous methods and the performance of the nanowires produced is also very high.

The way to make the nanowires is to put the raw material erbium chloride into carbon nanotubes with a diameter of about 2 nanometers, and then put it into a vacuum heat-resistant container for 7 days at a high temperature of 700 degrees Celsius. Finally, the erbium chloride changes and the chlorine atoms and erbium atoms interact with the carbon nanotubes to form the nanowires with a diameter of about 1.8 nanometers. That's just 1/10,000th the diameter of a human hair.

Previously, nanowires were made using special instruments to arrange atoms one by one, which was time-consuming and laborious. The new method is simple and the resulting nanowires are highly conductive and magnetic, the report said. If the carbon nanotubes were made with other compounds, it might also be possible to create nanowires that conduct electricity and are more magnetic, the scientists said. This new achievement is expected to be used to make a new generation of nanoscale semiconductor wires.
