摘要:
A method for placing nitride laser diode arrays on a thermally conducting substrate is described. The method uses an excimer laser to detach the nitride laser diode from the sapphire growth substrate after an intermediate substrate has been attached to the side opposite the sapphire substrate. A thermally conducting substrate is subsequently bonded to the side where the sapphire substrate was removed.
摘要:
Group III-V nitride semiconductors are used as light emitters for optoelectronic devices. To provide the desired range of bandgaps and band offsets in heterostructure devices, InGaN layers have to be grown. InGaN layers are difficult to grow because poor lattice mismatch between group III-V nitride alloys. Thus, a plurality of gratings or grooves are formed in the group III-V nitride layer in order to relieve strain between the group III-V nitride layer and the active region. The plurality of gratings allows segregation of In in a manner that optimizes the wavelength of light produced.
