Gallium Nitride: Cubic Phase GaN on Nano‐grooved Si

Gallium nitride is integrated on a CMOS‐compatible Silicon (100) substrate. On page 4492, C. Bayram et al. demonstrate thermodynamically stable, stress‐free, lowdefectivity GaN. The issue of lattice‐ and thermalmismatch between GaN and Si is reconciled through a new mask‐free local‐area epitaxy.

Ohmic Contacts to Gallium Nitride-Based Structures

2020-4-27  Abstract Studies of the characteristics of ohmic contacts to epitaxial and ion-doped gallium-nitride layers, based on the Cr/Pt/Au metallization system, are reported. The possibility of forming low-resistance contacts without the application of high-temperature treatment is shown. It is demonstrated, for AlGaN/GaN-based heterostructures, that the characteristics of Ti/Al/Ni/Au ohmic contacts

Gallium Nitride Diffractive Microlenses Using in

In this work, diffractive microlenses were fabricated in GaN using a gray-level mask and inductively coupled plasma etching technique. We also propose to insert the GaN/AIN band- pass filter in the microlenses to enhance the ultraviolet/visible rejection ratio. Due to high transparency of GaN and AIN in UV, the microlenses can potentially be used in a UV micro-optics system such as for solar
