Quantum Dots Offer New Platform for Fingertip Terahertz Devices

Our group developed an antenna that can aid in reducing sources of terahertz radiation down to the size of a fingertip. The antenna is a "sandwich" of semiconductor layers combined with quantum dots. The scientists demonstrated that such antennas can lay foundation for a new type of universal systems that are capable of both transmitting and receiving terahertz radiation. Compact devices, operating at terahertz range, can find applications in medicine and biology for tumor visualization and in aerospace industry for high-speed communication systems. The study was published in Laser & Photonics Reviews.
