Coulomb liquid
How it works Schematic showing how a five-electron droplet (shown in blue) is transported inside the selected potential minimum of a SAW. Electrostatic gates (yellow) are used to guide the electron droplet and create a Y-junction. The scale bar is 200 nm. (Courtesy: Nature/CC BY 4.0)
As few as five electrons in a semiconductor can exhibit collective behaviour, forming a “Coulomb l
