The simulation shows a quantum dot's differential conductance mapped against gate voltage and bias voltage, revealing the characteristic Coulomb diamond pattern of blockaded and conducting regions produced by discrete single-electron charging.
Sweep the gate-voltage and bias-voltage sliders to trace out the conductance map and watch how the size of the Coulomb diamonds changes with the island's charging energy and gate coupling.
Sliders for gate voltage and source-drain bias voltage over a conductance map
Single-electron transistors are sensitive enough to detect the motion of a small fraction of a single electron charge, making them some of the most precise electrometers ever built and a standard tool for reading out quantum bits in solid-state quantum computers.
