Coulomb blockade and charging energy
Adding one electron costs electrostatic energy.
$$E_C=\frac{e^2}{2C_\Sigma}$$
Physical intuition
Adding one electron costs electrostatic energy.
Deep dive: physical mechanism
A small capacitance yields discrete charge transitions and Coulomb diamonds.
What is measured experimentally?
Charge stability diagrams and bias triangles reveal addition energies.
Assumptions, noise and limitations
The constant-interaction model omits orbital and correlation effects.
Research and simulation exercise
