Title: Turbines
Inventor: HALLER BRIAN ROBERT
IPC: F01D9/00
Filed: 1995-05-06
Abstract: A steam turbine inlet chamber or 'inlet belt' is fed by steam pipes 13 and 15 at top and bottom, the inlet belt 9 being open on one annular face towards the turbine blades (2).

Title: Growth of buffer layer by molecular beam epitaxy
Inventor: HOOPER STEWART EDWARD
IPC: C30B23/02
Filed: 1997-11-15
Abstract: In order to grow a Group III-V nitride buffer layer 2 on a substrate 1 made of a different material to compensate for lattice-mismatching between the material of the substrate 1 and the material of a further layer 3 to be grown on the substrate, the substrate 1 is first placed in a vacuum chamber 10 at a reduced pressure and at an elevated temperature in the range of 300 to 800C. The necessary species for epitaxial growth by molecular beam epitaxy are then supplied to the vacuum chamber 10 from a supply conduit 20 and effusion cells 24 and 26 containing sources of gallium and optionally another species, such as aluminium or a dopant. The supply conduit 20 is used to supply ammonia as the precursor of the nitrogen required in the epitaxial growth process so as to supply nitrogen to the substrate 1 at such a rate as to cause epitaxial growth on the substrate 1 of a nitride buffer layer, made of GaN for example, of uniform thickness less than 2000A at a growth rate in the range of 2 to 10Ám/hr. Such a method enables high quality epilayers and optoelectronic devices, such as lasers and light-emitting diodes, to be grown by molecular beam epitaxy.
