Journal ArticleDOI
Cubic aluminum nitride and gallium nitride thin films prepared by pulsed laser deposition
Liduo Wang,Hoi Sing Kwok +1 more
TL;DR: In this paper, the effects of ambient pressure and substrate temperature on the structure of cubic aluminum nitride and cubic gallium nitride (GaN) films are systematically investigated and it is shown that the films are amorphous when the temperature and the pressure are too low.
Journal ArticleDOI
Fast electro-optical mode in photo-aligned reflective deformed helix ferroelectric liquid crystal cells.
Qi Guo,Zourab Brodzeli,Eugene P. Pozhidaev,Fan Fan,Vladimir G. Chigrinov,Hoi Sing Kwok,Leonardo Silvestri,François Ladouceur +7 more
TL;DR: The electrically controlled reflectance has been measured at subkilohertz driving voltage frequency for different polarizations of the incident light and compared quite successfully with the simulation results.
Journal ArticleDOI
Silole-containing poly(diphenylacetylene): Synthesis, characterization, and light emission
TL;DR: A disubstituted polyacetylene consisting of a poly(diphenylacetylene) backbone and a 1,2,3,4,5-pentaphenylsilole (SiC4Ph5) pendant was synthesized, and its light emission from both the backbone and the pendant were evaluated as mentioned in this paper.
Journal ArticleDOI
A fully self-powered, ultra-stable cholesteric smart window triggered by instantaneous mechanical stimuli
Jiaqi Wang,Jiaqi Wang,Cuiling Meng,Chun-Ta Wang,Chia-Hua Liu,Yong-Hsiang Chang,Cheng-Chang Li,Heng-Yi Tseng,Hoi Sing Kwok,Yunlong Zi +9 more
TL;DR: In this article, a fully self-powered, instantaneous-mechanical-stimuli-triggered, normally transparent smart window was developed based on an elaborately tailored cholesteric liquid crystal (LC) and a freestanding sliding triboelectric nanogenerator (FS-TENG).
Journal ArticleDOI
High performance self-aligned top-gate ZnO thin film transistors using sputtered Al2O3 gate dielectric☆
TL;DR: In this paper, a self-aligned top-gate zinc oxide (ZnO) thin film transistors (TFTs) utilizing high-k Al 2 O 3 thin film as gate dielectric are developed.
