PreviousPrevious project:Fig.1-a Representation of the semiconductor refrigerant heterostructure [Cha2005]. The quantum well of GaAs is cooled by injecting cold electrons (in blue) via resonant tunneling, and by extracting the hot carriers above the thicker barrier (in red).NextNext project:Fig.1: a) LDOS (arb. unit) of the quantum cascade cooler (QCC) calculated by NEGF. Horizontal and vertical arrows show the resonant tunneling and thermionic effects respectively. The green solid line represents the potential energy profile;
