Charge is measured in coulombs (C). Since electrons are so small and one electron will not have much of an effect anywhere, it is more useful to refer to large groups of electrons. One coulomb of ...

(Image: Osaka University) The charging energy (EC) is the energy required to add an extra electron to the nanostructure. It is given by EC = e2 / (2C), where e is the elementary charge and C is the ...
