摘要:
One embodiment of the present invention provides a method for fabricating an InGaAlN light-emitting semiconductor structure. During the fabrication process, at least one single-crystal sacrificial layer is deposited on the surface of a base substrate to form a combined substrate, wherein the single-crystal sacrificial layer is lattice-matched with InGaAlN, and wherein the single crystal layer forms a sacrificial layer. Next, the InGaAlN light-emitting semiconductor structure is fabricated on the combined substrate. The InGaAlN structure fabricated on the combined substrate is then transferred to a support substrate, thereby facilitating a vertical electrode configuration. Transferring the InGaAlN structure involves etching the single-crystal sacrificial layer with a chemical etchant. Furthermore, the InGaAlN and the base substrate are resistant to the chemical etchant. The base substrate can be reused after the InGaAlN structure is transferred.

A code lock is revealed. The code lock includes a housing, a return base, a plurality of locking seats, a fixed seat, a moveable seat, a code seat, a plurality of code members and a housing base arranged sequentially from top to bottom. A press button corresponding to each locking seat is disposed on the housing and each locking seat has at least one tooth that locks with a hook of the return base when the press button is pressed to push the locking seat. A stopping block is arranged at the bottom of each locking seat while the code member is set with a code post correspondingly. Moreover, the moveable seat includes a code area and a non-code area for mounting the code member and the code seat has a plurality of C-shaped holes corresponding to the code members. Thereby a simple-structured and easy-operated code lock is formed.

Aspects of this disclosure describe measuring intervals within a cardiac cycle to, for example, determine whether a patient is a candidate for cardiac therapy initiation or modification. The intervals may be measured in response to a trigger identifying a physiological event. The intervals and an identification of the physiological event may be stored. A physician or clinician may determine whether the patient is a candidate for cardiac therapy modification based on the measured intervals.

One embodiment of the present invention provides a semiconductor light-emitting device which includes: (1) a silicon (Si) substrate; (2) a silver (Ag) transition layer which is formed on a surface of the Si substrate, wherein the Ag transition layer covers the Si substrate surface; and (3) an InGaAlN, ZnMgCdO, or ZnBeCdO-based semiconductor light-emitting structure which is fabricated on the Ag-coated Si substrate. Note that the Ag transition layer prevents the Si substrate surface from forming an amorphous overcoat with reactant gases used for growing the semiconductor light-emitting structure.

A light-emitting device includes a substrate, a first doped semiconductor layer situated above the substrate, a second doped semiconductor layer situated above the first doped layer, and a multi-quantum-well (MQW) active layer situated between the first and the second doped layers. The device also includes a first electrode coupled to the first doped layer and a first passivation layer situated between the first electrode and the first doped layer in areas other than an ohmic-contact area. The first passivation layer substantially insulates the first electrode from edges of the first doped layer, thereby reducing surface recombination. The device further includes a second electrode coupled to the second doped layer and a second passivation layer which substantially covers the sidewalls of the first and second doped layers, the MQW active layer, and the horizontal surface of the second doped layer.

One embodiment of the present invention provides a method for fabricating a group III-V nitride structure with an ohmic-contact layer. The method involves fabricating a group III-V nitride structure with a p-type layer. The method further involves depositing an ohmic-contact layer on the p-type layer without first annealing the p-type layer. The method also involves subsequently annealing the p-type layer and the ohmic-contact layer in an annealing chamber at a predetermined temperature for a predetermined period of time, thereby reducing the resistivity of the p-type layer and the ohmic contact in a single annealing process.
