Pendeoepitaxial gallium nitride semiconductor layers on silicon carbide substrates

An underlying gallium nitride layer on a silicon carbide substrate is masked with a mask that includes an array of openings therein, and the underlying gallium nitride layer is etched through the array of openings to define posts in the underlying gallium nitride layer and trenches therebetween. The posts each include a sidewall and a top having the mask thereon. The sidewalls of the posts are laterally grown into the trenches to thereby form a gallium nitride semiconductor layer. During this lateral growth, the mask prevents nucleation and vertical growth from the tops of the posts. Accordingly, growth proceeds laterally into the trenches, suspended from the sidewalls of the posts. The sidewalls of the posts may be laterally grown into the trenches until the laterally grown sidewalls coalesce in the trenches to thereby form a gallium nitride semiconductor layer. The lateral growth from the sidewalls of the posts may be continued so that the gallium nitride layer grows vertically through the openings in the mask and laterally overgrows onto the mask on the tops of the posts, to thereby form a gallium nitride semiconductor layer. The lateral overgrowth can be continued until the grown sidewalls coalesce on the mask to thereby form a continuous gallium nitride semiconductor layer. Microelectronic devices may be formed in the continuous gallium nitride semiconductor layer.

By means of Red / ET recombination and direct cloning technologies, the NiF nitrogen fixation gene island in the genome of Pseudomonas stutzeri DSM4166, taken as a whole, is cloned into the genome of Pseudomonas protegens Pf5, so as to heterologously express the same successfully to obtain a genetically engineered strain Pf5-NiF, thereby bringing a biological nitrogen fixation function to Pseudomonas protegens Pf5 which does not own a biological nitrogen fixation function. In addition, gene-directed markerless knockout of retS gene in the genome of Pseudomonas protegens Pf5 is performed to obtain a genetically engineered strain Pf5-ΔretS. Thus, the expression levels of an antibiotic 2,4-diacetylphloroglucinol and red pigment are increased, and a mutant strain of Pseudomonas protegens Pf5 having a stronger bactericidal activity is obtained.
