摘要： In a well-known semiconductor laser, a multiple quantum well type active layer consisting of barrier layers and active layers or well layers, each of which has a thickness less than the de Broglie wavelength of electrons, is doped with an impurity, and the impurity density is made higher in the barrier layer than in the well layer. Further, in a case where the multiple quantum well active layer is held between p-type and n-type cladding layers, the well layer is undoped, the part of the barrier layer lying in contact with the well layer is undoped, and the other part of the barrier layer close to the p-type cladding layer is put into the n-conductivity type while that of the barrier layer close to the n-type cladding layer is put into the n-conductivity type. Desirably, the impurity density should range from about 1.times.10.sup.18 to about 1.times.10.sup.19 cm.sup.- 3.

摘要： A semiconductor device comprises a first superlattice layer consisting of a first semiconductor layer that contains impurities and a second semiconductor layer that contains impurities at a low concentration, said first superlattice layer being formed on a semiconductor substrate; and a second superlattice layer that covers that exposed side walls of said first superlattice layer. A disordered region is formed in the vicinity of the first semiconductor layer of the second superlattice layer in order to realize quantum wires with the conventional manufacturing process. This makes it possible to easily fabricate a laser device, a light-emitting diode and a transistor having quantum wires to enhance their performance.
