Abstract:

A composite comprising a monocrystalline substrate and one or more layers or films of monocrystalline IVA-VIA compounds and/or alloys formed thereon by a chemical vapor deposition process. The composite is formed at a preferred temperature range of approximately 450. degree. -650. degree. C. The IVA-VIA layer(s) are produced by the pyrolysis of a gas mixture containing metalorganic compounds. Where single crystal metallic oxide substrates of rhombohedral structure, such as sapphire, (. alpha. -Al. sub. 2 O. sub. 3), or of cubic structure, such as magnesium aluminate (spinel), are used for the growth of monocrystalline lead-containing films such as Pb. sub. 1-x Sn. sub. x Te, a nucleation layer of lead is preferably formed on the substrate prior to the pyrolysis of the mixed gaseous reactants. Using the present process, epitaxial monocrystalline IVA-VIA compounds and/or alloys can be grown on inorganic metal oxide substrates, such as cubic and rhombohedral oxides, on alkali halides and IIA fluorides, and on II-VI and III-V compounds. The compositions of the films can be varied without removing the composites from the deposition apparatus by changing the ratio of the reactant gases and the reaction temperature.

Abstract:

A structural building module has first and second upright cast structural members. Each of the first and second structural upright members include a wall portion and a roof portion. These structural members are initially supported on erection pads such that the wall portions are upright and the roof portions project toward one another such that the roof portions can be joined together. After joining the roof portions a structural base is formed in situ by casting. The structural base is attached to the wall portions of the structural members by entraining into the structural base, attaching members projecting out of the wall portions near their bottom edge.
