摘要: A quantum cascade detector includes a semiconductor substrate, and an active layer formed by laminating unit laminate structures each having absorption region with first barrier to second well transport third n-th layer. has thickness ½ or less of that thickest in one period, coupling smaller than exit period. The structure detection lower level arising from ground the layer, upper generated excitation for electrons.
