英文摘要 | PURPOSE:To economize the quantity of a V group element to be supplied by setting a cover up around a substrate crystal and maintaining the partial pressure of the V group element just before a substrate within a predetermined range when a III-V group compound semiconductor crystal is grown through a molecular-beam epitaxial method. CONSTITUTION:The substrate 2 is held into a vacuum vessel 1, the cylindrical cover 4 made of stainless steel is set up around the substrate, and liquid nitrogen is introduced 7 to cool the substrate. Accordingly, when the V group elements are difficult to adhere on the cover 4, the number of molecules reaching from an evaporating cell 8 and the number of molecules projected of a V group gas as an atmosphere are made approximately the same in the vicinity of the substrate and the degree of vacuum is kept within the range of 10-10 Torr partial pressure, the quantity of the V group elements supplied can be reduced by half. It is proper that a distance between the substrate 2 and the cover 4 is approximately 10cm, and the substrate crystal is polluted when the distance is too short. |
