英文摘要	PCT No. PCT/GB94/00406 Sec. 371 Date Nov. 2, 1995 Sec. 102(e) Date Nov. 2, 1995 PCT Filed Mar. 2, 1994 PCT Pub. No. WO94/20990 PCT Pub. Date Sep. 15, 1994A quantum well device has an active region adapted to pass a tunneling current of charge carriers and comprising layers of material forming alternating potential barriers and potential wells. The structure defines, in use, a first potential well at one end of the active region, said first potential well defining a first quasi-defined energy level, and to further define second and third quasi-defined energy levels. The relative heights and thicknesses of the potential barriers when the device is in use are structured so that the first quasi-defined energy level has a longer lifetime than the second and third quasi-defined energy levels and there is a degree of coupling between the three quasi-defined energy levels which is strongest between the second and third quasi-defined energy levels. The transmission coefficient through the active region shows a resonance peak at each of the energies of the three quasi-defined energy levels. The transmission peak at the energy of the first quasi-defined energy level is greater than the transmission peaks at the energies of the second and third quasi-defined energy levels, respectively, and when in use, the energy of the first quasi-defined energy level lies between the energies of the second and third quasi-defined energy levels but is greater or less than the average of the energies of the second and third quasi-defined energy levels.
