Applied physics: Nanotube antennas
M. S. Dresselhaus1
Abstract
An antenna array that is metres high and wide can detect and transmit radio waves. This effect has now been demonstrated at much smaller electromagnetic wavelengths in a nanoscale array of carbon nanotubes.
In Applied Physics Letters, Wang et al.1 show in a clear way that an array of aligned carbon nanotubes can behave as an electromagnetic antenna. Their practical demonstration not only confirms a predicted effect but also points to its use in practical devices.
