The micro-LED roadmap: status quo and prospects

open access: yesJPhys Photonics, 2023
Micro light-emitting diode (micro-LED) will play an important role in the future generation of smart displays. They are found very attractive in many applications, such as maskless lithography, biosensor, augmented reality (AR)/mixed reality etc, at the ...

Color Superconductivity in Compact Stars and Gamma Ray Bursts [PDF]

open access: yes, 2003
We study the effects of color superconductivity on the structure and formation of compact stars. We show that it is possible to satisfy most of recent observational boundaries on masses and radii if a diquark condensate forms in a hybrid or a quark star.

Transparent organic light-emitting diodes with different bi-directional emission colors using color-conversion capping layers [PDF]

open access: yes, 2017
We report a study on transparent organic light-emitting diodes (OLEDs) with different bidirectional emission colors, enabled by color-conversion organic capping layers. Starting from a transparent blue OLED with an uncapped Ag top electrode exhibiting an

Structural Optimization of Vertically-Stacked White LEDs with a Yellow Phosphor Plate and a Red Quantum-Dot Film

open access: yesNanomaterials, 2022
A remote-type white light-emitting diode (LED) consisting of a red quantum-dot (QD) film and a yellow phosphor plate was studied by both experiment and optical simulation.

Nuclear physics with a medium-energy Electron-Ion Collider [PDF]

open access: yes, 2011
A polarized ep/eA collider (Electron-Ion Collider, or EIC) with variable center-of-mass energy sqrt(s) ~ 20-70 GeV and a luminosity ~ 10^{34} cm^{-2} s^{-1} would be uniquely suited to address several outstanding questions of Quantum Chromodynamics (QCD)

An FPGA-Based Simple RGB-HSI Space Conversion Algorithm for Hardware Image Processing

open access: yesIEEE Access, 2020
In this paper, a new, low-complexity, easy-to-implement hardware method for color space conversion between the red-green-blue (RGB) and the hue-saturation-intensity (HSI) color spaces called the simple RGB-HSI space conversion (S-SC) algorithm is ...
