Efficient terahertz upconversion in topological insulator quantum material. (IMAGE)
Caption
Incident terahertz radiation (left) that is incident on a topological insulator metamaterial is efficiently upconverted to its third harmonic, thanks to strong nonlinearity and efficient electronic surface-to-bulk heat dissipation.
