Ultra-wide-field Fundus Image Synthesis Using Various GAN Models

open access: yesJOIV: International Journal on Informatics Visualization, 2022
Many people lose sight due to diabetic retinopathy. The reason that diabetic retinopathy is dangerous is that it cannot return to its pre-onset state after the disease's onset. Most patients take fundus images that capture the retina, and the doctor uses

Improved InGaN/GaN light-emitting diodes with a p-GaN/n-GaN/p-GaN/n-GaN/p-GaN current-spreading layer [PDF]

open access: yesOptics Express, 2013
This work reports both experimental and theoretical studies on the InGaN/GaN light-emitting diodes (LEDs) with optical output power and external quantum efficiency (EQE) levels substantially enhanced by incorporating p-GaN/n-GaN/p-GaN/n-GaN/p-GaN (PNPNP-GaN) current spreading layers in p-GaN.

Polarization effects in AlGaN/GaN and GaN/AlGaN/GaN heterostructures [PDF]

open access: yesJournal of Applied Physics, 2003
The influence of AlGaN and GaN cap layer thickness on Hall sheet carrier density and mobility was investigated for Al0.32Ga0.68N/GaN and GaN/Al0.32Ga0.68N/GaN heterostructures deposited on sapphire substrates. The sheet carrier density was found to increase and saturate with the AlGaN layer thickness, while for the GaN-capped structures it decreased ...

Detection and localization enhancement for satellite images with small forgeries using modified GAN-based CNN structure

open access: yesIJAIN (International Journal of Advances in Intelligent Informatics), 2020
The image forgery process can be simply defined as inserting some objects of different sizes to vanish some structures or scenes. Satellite images can be forged in many ways, such as copy-paste, copy-move, and splicing processes.

Growth of GaN on porous SiC and GaN substrates [PDF]

open access: yesJournal of Electronic Materials, 2003
GaN films were grown on porous SiC and GaN templates using both plasma-assisted molecular beam epitaxy (PAMBE) and metal-organic chemical vapor deposition (MOCVD) to evaluate possible advantage of epitaxy on a porous substrate. For the growth of GaN on porous SiC by PAMBE, transmission electron microscopy (TEM) observations indicate that the exposed ...

Cubic GaN and InGaN/GaN quantum wells

open access: yesApplied Physics Reviews, 2022
LEDs based on hexagonal InGaN/GaN quantum wells are dominant technology for many lighting applications. However, their luminous efficacy for green and amber emission and at high drive currents remains limited. Growing quantum wells instead in the cubic phase is a promising alternative because, compared to hexagonal GaN, it benefits from a reduced ...
