Abstract: This paper presents a review of recent advances of Gallium Nitride (GaN) and Zinc Oxide (ZnO) based hybrid structures materials and devices. GaN and ZnO have gained substantial interest in the research area of wide bandgap semiconductors due to their unique electrical, optical and structural properties. GaN and ZnO are important semiconductor materials with applications in blue and ultraviolet (UV) optoelectronics. Both materials have similar physical properties. GaN and ZnO as hybrid material have received much attention due to their unique potential applications. Several potential optical applications are being fabricated based on GaN and ZnO hybrid materials such as optical wave guide, light emitting diodes (LEDs), and laser diodes (LDs). The recent aspects of GaN and ZnO hybrid based devices are presented and discussed.Abstract: This paper presents a review of recent advances of Gallium Nitride (GaN) and Zinc Oxide (ZnO) based hybrid structures materials and devices.

Abstract: Synthesis of nanoparticles was done by green method. Silver nitrate was used as the silver precursor, while the fruit juices of the citrus fruits (Citrus sinensis, Citrus limetta, Citrus aurantifolia, Citrus paradisi) were used as reducing and stabilizing agents. The nanoparticle formation was confirmed with the visible colour change from colourless to characteristic reddish brown. the surface plasmon resonance peak was at 451 and 452 nm for the silver nanoparticles The antimicrobial activities of these nanoparticles were studied against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Bacillus subtilis. Generally, MIC values of the samples against the microorganism tested ranged from 25-100mg/ml. Pseudomonas aeruginosa was the most sensitive (while Staphylococcus aureus and Bacillus subtilis were the least sensitive to the silver nanoparticles).Abstract: Synthesis of nanoparticles was done by green method.
