摘要:
A new and distinct cultivar of the species Actinidia chinesis Planch is described. ‘AU Golden Sunshine’ has a low chilling requirement, fruit is early maturing, excellent flavor with a non acid sweet taste and a high percent soluble solids and dry matter content. ‘AU Golden Sunshine’ matures about 20 days after ‘AU Golden Dragon’ and 30 days before ‘Hort 16A’ (patented), the industry standard for golden flesh kiwi cultivars. ‘AU Golden Sunshine’ fruit quality indices are similar to fruit quality indices of ‘AU Golden Dragon’ and ‘Hort 16A’ (patented). There have been no differences in plant performance and fruit quality of ‘AU Golden Sunshine’ plants grown in China and Alabama.
摘要:
An LED device (90) includes: an epitaxial structure (100) having a plurality of layers of semiconductor material and forming an active light-generating region (120) which generates light in response to electrical power being supplied to the LED device (90); and, a substrate (200) that is substantially transparent in a wavelength range corresponding to the light generated by the active light-generating region (120). The substrate has first and second opposing end faces (202, 206) and a plurality of side walls (210) extending therebetween, including a first side wall having a first portion thereof that defines a first surface (212, 214, 216, 218) which is not substantially normal to the first face (202) of the substrate (200). The epitaxial structure (100) is disposed on the first face (202) of the substrate (200).
摘要:
A repeatable and uniform low doped layer is formed using modulation doping by forming alternating sub-layers of doped and undoped nitride semiconductor material atop another layer. A Schottky diode is formed of such a low doped nitride semiconductor layer disposed atop a much more highly doped nitride semiconductor layer. The resulting device has both a low on-resistance when the device is forward biased and a high breakdown voltage when the device is reverse biased.

A new and distinct cultivar of the species Actinidia chinesis Planch is described. This cultivar named ‘AU Golden Tiger’ was developed from seeds collected from an open pollinated ‘AU Golden Dragon’ fruit. The seedling has been reproduced by rooted cuttings and grafting and tested in replicated cultivar trials. It maintains all of its unique characteristics after each propagation. Its bloom period overlaps the bloom period of ‘AU Golden Sunshine’ and is the pollinizer for ‘AU Golden Sunshine’.
摘要:
A nitride semiconductor is grown on a silicon substrate by depositing a few mono-layers of aluminum to protect the silicon substrate from ammonia used during the growth process, and then forming a nucleation layer from aluminum nitride and a buffer structure including multiple superlattices of AlRGa(1-R)N semiconductors having different compositions and an intermediate layer of GaN or other Ga-rich nitride semiconductor. The resulting structure has superior crystal quality. The silicon substrate used in epitaxial growth is removed before completion of the device so as to provide superior electrical properties in devices such as high-electron mobility transistors.

A sapphire wafer having a thickness greater than 125 microns and having devices disposed thereon is laser scribed to form a grid array pattern of laser scribe lines laser scribed into the sapphire wafer. The sapphire wafer is separated along the laser scribe lines to separate a plurality of device dice defined by the grid array pattern of laser scribe lines. Each device die includes (i) a device and (ii) a portion of the sapphire wafer having the thickness greater than 125 microns. In some embodiments, a GaN LED device die includes a GaN based LED device, and a sapphire substrate supporting the GaN based LED device. The sapphire substrate has: (i) a thickness greater than 125 microns effective for increased light extraction due to a lower critical angle for total internal reflection; and (ii) sides generated by laser scribing.
摘要:
A light emitting semiconductor device die (10, 110, 210, 310) includes an electrically insulating substrate (12, 112). First and second spatially separated electrodes (60, 62, 260, 262, 360, 362) are disposed on the electrically insulating substrate. The first and second electrodes define an electrical current flow direction directed from the first electrode to the second electrode. A plurality of light emitting diode mesas (30, 130, 130′, 230, 330) are disposed on the substrate between the first and second spatially separated electrodes. Electrical series interconnections (50, 150, 250, 350) are disposed on the substrate between neighboring light emitting diode mesas. Each series interconnection carries electrical current flow between the neighboring mesas in the electrical current flow direction.
摘要:
A lateral conduction Schottky diode includes multiple mesa regions upon which Schottky contacts are formed and which are at least separated by ohmic contacts to reduce the current path length and reduce current crowding in the Schottky contact, thereby reducing the forward resistance of a device. The multiple mesas may be isolated from one another and have sizes and shapes optimized for reducing the forward resistance. Alternatively, some of the mesas may be finger-shaped and intersect with a central mesa or a bridge mesa, and some or all of the ohmic contacts are interdigitated with the finger-shaped mesas. The dimensions of the finger-shaped mesas and the perimeter of the intersecting structure may be optimized to reduce the forward resistance. The Schottky diodes may be mounted to a submount in a flip chip arrangement that further reduces the forward voltage as well as improves power dissertation and reduces heat generation.
摘要:
A new and distinct cultivar of the species Actinidia chinesis Planch is described. ‘AU Golden Dragon’ has a low chilling requirement, fruit is very early maturing, excellent flavor with a non acid sweet taste, and high soluble solids and dry matter content. ‘AU Golden Dragon’ matures about 50 days ahead of ‘Hort 16A’ (patented), the industry standard for golden flesh kiwi, therefore, the two cultivars will not compete in the market place. ‘AU Golden Dragon’ fruit quality indices are similar to fruit quality indices of ‘Hort 16A’ (patented). There have been no differences in plant performance and fruit quality of ‘AU Golden Dragon’ plants grown in China and Central Alabama.
