Abstract:
Electric current is a flow of charged elementary particles. In a semiconductor device, ballistic electrons move at high speed, making it difficult to overcome them one by one. The controlled collision of the individual electrons can provide the time resolution it takes for one electron to interrogate another. The principle of operation of the electron colliding circuit is similar to hitting one fast-moving projectile with another well-timed shot. Therefore, the challenge is to precisely synchronize the two electrons to exploit their interactions.

Electron colliding on a chip

Braunschweig, Germany | Posted on June 30, 2023

To this end, scientists at PTB have now developed a nanoscale collider on a semiconductor chip. Such a device integrates two single electron sources which can be triggered to a picosecond accuracy. The single electron detector records every impact. A pair of electrons is generated by two separate sources and placed on intersecting paths in such a way that collisions can occur. If the sources are properly synchronized, interactions between the electron pairs will determine which final signaling pathway will be reached by which individual particle. Despite the brevity of the encounter, theoretical models developed at the University of Latvia with input from the Technical University of Braunschweig made it possible to deduce the trajectory of an electron from experimental data and find a way to control the two-electron interaction for future applications. This time-resolved interaction demonstration not only shows that such flying electrons can be used as ultrafast sensors or switches, but also proves a mechanism for generating quantum entanglement—a key component of quantum computing. Coming together with the consistent findings of a research team led by NEEL and NPL, these results have been published and introduced by the “News & Views” comment in Nature Nanotechnology.
