A simpler source of THz radiation

Plasmon-coupled semiconductor surface states can down-convert 1550nm optical wavelengths to terahertz frequencies four-orders of magnitude more efficiently than non-linear optical methods, according to UCLA. When a crystal is a semiconductor – p-doped InAs in this case – the ‘surface states’ created by the left-over bonds that are inevitable at the surface of a crystal lattice ...
