PURPOSE:To eliminate a disadvantage of distortion quantum well structure that mismatching of lattice (distortion) is gradually eased and quantum effect can be reduced as the crystals are laminated. CONSTITUTION:In a semiconductor element having distortion quantum well structure, a semiconductor of mixed crystal having the structure showing a little mismatching of lattice with a semiconductor substrate 10 is used as barrier layers 61 to 66. |
