Transference through a barrier. Tunnel effect. A tunnel effect barrier seen as balli sticconductance with small transmission. Limit for barrier resistance to exist tunnel effect. Electrostatic energy and Coulomb blockade effect. Orthodox condition for an electron to be transfer across the barrier. Metallic island between two barriers in a canal - double barrier. Single electron tunneling. Asymmetric double barrier. Single electron transistor (SET). Representation Vgate as function of Vsource-drain- stability diagram (diamond diagram).
