Abstract
In a process for the production of semiconductor single crystals of an alloy having a predetermined composition, the components of the alloy are deposited from the gas or vapour phase on the surface of a seed crystal of one component, and the ratio of the components deposited is gradually changed from an initial composition consisting almost exclusively of the same component as the seed crystal to the predetermined composition. The seed crystal may be silicon on which silicon with a small amount of germanium is deposited from a gas mixture, the proportion of germanium being increased as the deposition progresses, until the desired composition is reached; the proportion of silicon deposited may then be reduced until a zone of the crystal consisting only of germanium is obtained. The gas mixture may consist of silicon chloride and germanium chloride, the proportions being varied as required, the silicon and germanium being obtained by thermal decomposition and/or reduction with hydrogen. Donor and acceptor material may be added to the gas mixture for inclusion in the growing crystals to obtain zones of different type or degree of conductivity. Acceptor material may be added to the first part of the crystal to obtain a strong p-conductivity zone, followed by donor material and then by acceptor material to obtain a P-N-P-junction, the strongly-conductive zone serving as an emitter. Crystals may be grown having a middle zone of a material or alloy of desired band-width, diffusion length and carrier mobility, as a base with adjacent layers of different materials or alloys as emitters or collectors or intermediate layers such as hook or intrinsic zones.
