摘要： In a hydrothermal process for manufacturing crystals of metal carbonates, including single crystals of lead carbonate of the cerussite crystalline form, the nutrient material consists of a carbonate or basic carbonate of the said metal, the solvent medium consists of a 0.5 to 5.0 molar aqueous solution of an alkali metal bicarbonate, and the heating is carried out in an autoclave under controlled temperature conditions such that the exterior of the autoclave wall adjacent to the nutrient and the solvent medium in the vicinity thereof is maintained at 200.degree. C to 400.degree. C, and that the exterior of the autoclave wall adjacent to the region of the solvent medium remote from the nutrient is maintained at 170.degree. C to 315.degree. C and at a temperature from 5.degree. C to 150.degree. C lower than that of the exterior of the autoclave wall adjacent to the nutrient: a temperature gradient is thus produced in the solvent medium and crystalline metal carbonate is deposited in a region remote from the nutrient, as small crystals on the autoclave wall or as crystal growth on seeds.

摘要： Described is a double heterostructure junction laser in which the active region tapers to zero thickness within the structure, causing light to couple into an adjacent, underlying passive waveguide layer. Also described is a laser device in which the passive waveguide layer terminates in a region of increased thickness adjacent a laser output face. In addition, LPE and MBE techniques for fabricating the tapers are described.

摘要： A PROCESS IF DISCLOSED FOR MANUFACTURING MERCURYDOPED GERMANIUM PHOTOCONDUCTOR MATEIAL HAVING A SHORT TIME CONSTANT AT LIQUID NEON TEMPERATURES. THE PROCESS INCLUDES REFINING THE GERMANIUM BY A NUMBER OF MOLTEN ZONE-REFINING PASSES TO REDUCE TH IMPURITIES WHICH ACT AS SHALLOW ACCEPTORS TO A LEVEL ON THE ORDER OF 10**12 ATOMS/CM.3 OR LESS AND THEN COMPENSATING THE REMAINING SHALLOW ACCEPTORS WITH SHALLOW DONORS SUCH AS ANTIMONY OR ARSENIC AND THEN DOPING THE GERMANIUM WITH MERCURY FROM THE VAPOR STATE TO A LEVEL ON THE ORDER OF 10**14 ATOMS/CM.3 OR GREATER.

摘要： 1,203,973. Yttrium iron garnets. WESTERN ELECTRIC CO. Inc. 14 Nov., 1967 [15 Nov., 1966], No. 51783/67. Heading CIA. [Also in Divisions H1 and H4] Crystals of Y 3-x M 1 x Fe 5-y M 11 y O 12 garnet (where M 1 is a trivalent rare earth Nos. 57-71, M 11 is Ga and/or Al, x is 0-0À3, and y is 0-1.25) are grown by placing a seed crystal and a nutrient mass in a closed vessel in a 10-25 M solution of KOH in H 2 O or D 2 O, heating the solution to at least 350‹ C. while under a pressure exceeding the critical pressure, and maintaining a temperature difference between the seed and the mass of at least 5‹ C. The temperature is preferably 350-425‹ C., the pressure 8000-35000 psi, and the temperature difference 10-50‹ C. The seed crystal orientation may be (100), (211), (111) or (110). The nutrient mass may be a mixture of the oxides, which may be sintered, or crystals grown hydrothermally under maximum growth conditions. The vessel may be Pt lined and may be filled to 70-95% of its volume before heating. A baffle may be placed between the nutrient mass in the bottom of the vessel and the crystals suspended above, to maintain the temperature difference.
