摘要:
A kind of growth method of non-polarized-plane InN which is growing m-plane InN and In-rich m-plane InGaN on LiA1O2 (100) substrate by the metal organic chemical vapor deposition (MOCVD), and m-plane is one kind of non-polarized-plane, In-rich denotes that the component of In x is higher than 0.3 in InxGa1−xN. The invention synthetically grows m-plane InN and In-rich m-plane InGaN using LiA1O2 (100) as substrate which will be disposed and the buffer by MOCVD. And the non-polarized-plane InN would be produced through choosing appropriate substrate and the technique condition of growth as well as using the design of buffer by MOCVD.

摘要:
This invention presents a growth method for GaN based quantum wells red light LED structure by MOCVD epitaxy growth system, GaN based GaN/InGaN quantum wells red light LED structure material is obtained. The In mole fraction (x) for quantum well material InGaN is controlled between 0.1 and 0.5. This invention realizes the lumiscience of long wave length red light in group III nitrides. Aiming at the problem of difficulty in growing high In composition InGaN material, this invention solves this problem by controlling and adjusting the flux of organic Ga source and In source, growth temperature, time, and the flux of ammonia, and the mole ratio of N to Ga. By strictly controlling the conditions such as temperature and the flux ratio of reactant in the whole process, this invention determines the radiation wave length of quantum well, realizes the lumiscience of long wave length, and obtained GaN based GaN/InGaN quantum well red light LED structure.
摘要:
In various embodiments devices and methods are provided for an improved dry-cooling condensation system. In certain embodiments the methods involve receiving steam from a source of steam (e.g., a power plant); condensing the steam into water while transferring the latent heat of the steam into the latent heat of a thermal storage material; and dissipating the latent heat from the thermal storage material at a later time when the ambient temperature is lower than the ambient temperature at the time the steam was condensed into water.
