Terahertz (THz) waves, which are electromagnetic waves with frequencies between 0.3 and 30 THz, have attracted much attention in recent years due to their potential applications in various fields such as medical imaging, security, and communication. Now, a team of researchers from China and the US have developed a new type of THz transistors based on two-dimensional (2D) plasmons. This new device has an extremely high sensitivity and a broad operation bandwidth, which could open up new possibilities for THz wave applications.
