20130203243 | METHODS FOR ENHANCING P-TYPE DOPING IN III-V SEMICONDUCTOR FILMS - Methods of doping a semiconductor film are provided. The methods comprise epitaxially growing the III-V semiconductor film in the presence of a dopant, a surfactant capable of acting as an electron reservoir, and hydrogen, under conditions that promote the formation of a III-V semiconductor film doped with the p-type dopant. In some embodiments of the methods, the epitaxial growth of the doped III-V semiconductor film is initiated at a first hydrogen partial pressure which is increased to a second hydrogen partial pressure during the epitaxial growth process. | 08-08-2013 |
20140027710 | QUANTUM DOT AND NANOWIRE SYNTHESIS - A self-assembled semiconductor nanostructure includes a core and a shell, wherein one of the core or the shell is rich in a strained component and the other of the core or the shell is rich in an unstrained component, wherein the nanostructure is a quantum dot or a nanowire. A method includes growing a semiconductor alloy structure on a substrate using a growth mode that produces a semiconductor alloy structure having a self-assembled core and shell and allowing the structure to equilibrate such that one of the core or the shell is strained and the other is unstrained. Another method includes growing at least one semiconductor alloy nanostructures on a substrate, wherein the nanostructure comprises a strained component and an unstrained component, and controlling a compositional profile during said growing such that a transition between the strained component and an unstrained component is substantially continuous. | 01-30-2014 |

20110215275 | METHODS USING SURFACTANTS TO CONTROL UNINTENTIONAL DOPANT IN SEMICONDUCTORS - The use of surfactants that do not themselves act as dopants and are isoelectronic with either the group III or group V host atoms during OMVPE growth significantly reduces the incorporation of background impurities such as carbon, oxygen, sulfur and/or silicon. For example, the use of the surfactants Sb or Bi significantly reduces the incorporation of background impurities such as carbon, oxygen, sulfur and/or silicon during the OMVPE growth of III/V semiconductor materials, for example GaAs, GaInP, and GaP layers. As a result, an effective method for controlling the incorporation of impurity atoms is adding a minute amount of surfactant during OMVPE growth. | 09-08-2011 |
20140130731 | USE OF SURFACTANTS TO CONTROL ISLAND SIZE AND DENSITY - Methods of controlling island size and density on an OMVPE growth film may comprise adding a surfactant at a critical concentration level, allowing a growth phase for a first period of time, and ending the growth phase when desired island size and density are achieved. For example, the island size and density of an OMVPE grown InGaN thin film may be controlled by adding an antimony surfactant at a critical concentration level. | 05-15-2014 |

20090308658 | LATCH SYSTEM FOR FRICTION-LOCKED TUBULAR MEMBERS - A technique for securing drilling riser joints in a drilling riser string is presented. The drilling riser joints have a tubular housing that has a box configuration on one end and a pin configuration on the other end. The drilling riser string is assembled by connecting the pin end of one drilling riser joint to the box end of an adjoining drilling riser joint. A moveable ring is used to connect adjoining drilling riser joints. The moveable ring is used to drive a fastener, such as a dog, of one drilling riser joint against the adjoining drilling riser joint. The moveable ring is driven axially from a first position, where the fastener is not engaged against the adjoining drilling riser joint, to a second position where the fastener is engaged against the adjoining drilling riser joint. A latch is used to prevent the moveable ring from moving inadvertently from the second position. This prevents the drilling riser joints from disconnecting inadvertently. | 12-17-2009 |

Each of the upper thrust sleeves transfer upward thrust imposed by the buoyancy module assembly to an upper support flange mounted to the central riser pipe. A pair of lower thrust sleeves slide over two of the auxiliary lines. Each lower thrust sleeve has a lower thrust flange that is engaged by a lower end of the buoyancy module assembly. Each of the lower thrust sleeves transfer weight of the buoyancy module assembly while out of water to a lower support flange mounted to the central riser pipe. | 10-28-2010 |

20110214877 | ACTUATION ASSEMBLY FOR RISER CONNECTION DOG - A box and pin coupling for a drilling riser having an actuator assembly with an attached dog. The actuator assembly includes an actuation rod having an end affixed to the dog. A portion of the rod is circumscribed by an annular sleeve, where the outer surface of the sleeve is threadingly attached to one of the box or pin. A shoulder is formed on the rod outer circumference between the sleeve and the end of the rod attached to the dog. A retainer cap is provided on the end of the rod opposite where it attaches to the dog. The sleeve abuts the rod on one end, and the retainer cap on the other, so that rotating the sleeve axially moves the actuation rod, that in turn moves the attached dog into or out of engagement with a profile on the other of the box or pin. | 09-08-2011 |
