GROWTH OF II-VI COMPOUND SEMICONDUCTOR

PURPOSE:To allow growth of a p-type II-VI compound having sufficiently high carrier concentration or a II-VI compound semiconductor having low defect density and excellent crystallization. CONSTITUTION:At the time of vapor growth of a p-type II-VI compound semiconductor on a semiconductor substrate such as a GaAs substrate by a molecular beam epitaxial method, a semiconductor substrate 1 having a main surface being off by a small angle from a (100) surface in the direction by a small angle, and a main surface being off in the (011) direction by a small angle or a main surface being off in the (01-1) direction by a small angle further a main surface being off in the (011) direction by a small angle is used. In order to make a II-VI compound semiconductor of low defect density to grow, especially the semiconductor substrate 1 having a main surface being off from the (100) in the (01-1) direction by a small angle is used.
