Abstract: Existing pressure oscillations created by axial or centrifugal fans in a diverging shroud are utilized to power a passive, acoustic jet, the nozzle of which directs high momentum flux gas particles essentially tangentially into the boundary layer of the flow in a diffuser, or a duct, the fluid particles in the resonant chamber of the passive acoustic jet being replenished with low momentum flux particles drawn from the fluid flow in a direction normal to the surface, thereby to provide a net time averaged flow of increased momentum flux particles to defer, even eliminate, the onset of boundary layer separation in the diffuser or duct. The passive acoustic jet is used in the vicinity of fan blade tips to alleviate undesirable flow effects in the tip region, such as leakage.

Abstract: A method for protecting the surface of a semiconductor material (30, 50) from damage and dopant passivation is described. A barrier layer (32, 52) of dense or reactive material is deposited on the semiconductor material shortly after growth in a growth reactor (10) such as a MOCVD reactor, using the MOCVD  source gasses. The barrier layer (32, 52) blocks the diffusion of hydrogen into the material. The reactor (10) can then be cooled in a reactive or non-reactive gas ambience. The semiconductor material can then be removed from the reactor (10) with little or no passivation of the dopant species. The barrier layer (32, 52) can be removed using a variety of etching processes, including wet chemical etching or can be left at the semiconductor material for surface protection. The barrier layer (32, 52) can also be a gettering layer that chemically binds hydrogen trapped in the semiconductor material and/or blocks hydrogen diffusion into the material.
