The Eriksson group, including first author, grad student Sam Neyens, recently published the paper “Measurements of Capacitive Coupling Within a Quadruple-Quantum-Dot Array” in Physical Review Applied. In it, they present measurements of the capacitive coupling energy and the interdot capacitances in a linear quadruple-quantum-dot array in undoped Si/SiGe. They provide a model for the capacitive coupling energy based on the electrostatics of a network of charge nodes joined by capacitors, which shows how the coupling energy should depend on inter-double-dot and intra-double-dot capacitances in the network, and find that the expected trends agree well with the measurements of coupling energy.
