摘要:
A method of growing high-quality, group-III nitride, bulk single crystals. The group III-nitride bulk crystal is grown in an autoclave in supercritical ammonia using a source material or nutrient that is a group III-nitride polycrystals or group-III metal having a grain size of at least 10 microns or more and a seed crystal that is a group-III nitride single crystal. The group III-nitride polycrystals may be recycled from previous ammonothermal process after annealing in reducing gas at more then 600° C. The autoclave may include an internal chamber that is filled with ammonia, wherein the ammonia is released from the internal chamber into the autoclave when the ammonia attains a supercritical state after the heating of the autoclave, such that convection of the supercritical ammonia transfers source materials and deposits the transferred source materials onto seed crystals, but undissolved particles of the source materials are prevented from being transferred and deposited on the seed crystals.
摘要:
A method to suppress thermal conductivities of nitride films by using stacking faults and/or nano-scale In-composition fluctuation(s). Therefore, the present invention reduces thermal conductivity of nitride while keeping electrical conductivity high. In addition, In composition fluctuations can enhance the Seebeck coefficient through thermionic emission. The present invention further discloses a nitride based (e.g. GaN) thermoelectric lateral device with a short length.

摘要:
A method for increasing the luminous efficacy of a white light emitting diode (WLED), comprising introducing optically functional interfaces between an LED die and a phosphor, and between the phosphor and an outer medium, wherein at least one of the interfaces between the phosphor and the LED die provides a reflectance for light emitted by the phosphor away from the outer medium and a transmittance for light emitted by the LED die. Thus, a WLED may comprise a first material which surrounds an LED die, a phosphor layer, and at least one additional layer or material which is transparent for direct LED emission and reflective for the phosphor emission, placed between the phosphor layer and the first material which surrounds the LED die.

摘要:
Provided is a computer system, in which a storage system includes a first control module for logically dividing first resources of the storage system and operating them as independent virtual storage systems. A computer includes a second control module for logically dividing second resources of the computer and operating them as independent virtual machines. The computer system holds first information indicating a correlation among the virtual machine, the virtual storage system, and the first resources. The first control module specifies the first resource allocated to the virtual storage system whose power is cut based on the first information, and powers off the specified first resource. Thus, system power consumption can be reduced by managing power of the storage system shared by a plurality of virtual machines in a virtualization environment.
