Abstract
The ability to design gate capacitances to quantum dots is critical for many applications of quantum dots from quantum information and single electron logic to standards. We have studied and simulated many multi-gate silicon quantum dot devices fabricated with different dimensions and can draw three conclusions. (1) The gate capacitances to the quantum dots are reproducible to within 10% for nominally identical devices. (2) Gate capacitances scale with device dimensions. (3) A capacitance simulator can predict gate capacitances to within 20% without using any fitting parameters.Citation
