Yi Fan Huang,Yi Fan Huang,Surojit Chattopadhyay,Yi-Jun Jen,Cheng Yu Peng,Tze An Liu,Yu-Kuei Hsu,Ci-Ling Pan,Hung Chun Lo,Chih Hsun Hsu,Yuan Huei Chang,Chih Shan Lee,Kuei-Hsien Chen,Li-Chyong Chen +13 more
TL;DR: A simple aperiodic array of silicon nanotips on a 6-inch wafer with a sub-wavelength structure that can suppress the reflection of light at a range of wavelengths from the ultraviolet, through the visible part of the spectrum, to the terahertz region is reported.
Journal ArticleDOI
Anti-reflecting and photonic nanostructures
Surojit Chattopadhyay,Y.F. Huang,Y.F. Huang,Yi-Jun Jen,Abhijit Ganguly,Kuei-Hsien Chen,Kuei-Hsien Chen,Li-Chyong Chen +7 more
TL;DR: In this article, a review of state-of-the-art anti-reflecting (AR) techniques, reported over the last half a century, and their guiding principles to predict a logical trend for future research in this field are presented.
Journal ArticleDOI
Growth of Single-Crystalline Wurtzite Aluminum Nitride Nanotips with a Self-Selective Apex Angle†
Shih Chen Shi,Chia-Fu Chen,Surojit Chattopadhyay,Zon Huang Lan,Kuei-Hsien Chen,Li-Chyong Chen +5 more
TL;DR: In this paper, a self-selective apex angle in aluminum nitride nanotip growth is proposed, where the thickness of the gold-catalyst layer plays a critical role in controlling the size of the tip; in addition, a catalyst-free growth mode has been observed, which results in lesser control over the nanoteip morphology.
Journal ArticleDOI
Surface-Enhanced Raman Spectroscopy Using Self-Assembled Silver Nanoparticles on Silicon Nanotips
TL;DR: In this article, a new substrate for surface-enhanced Raman spectroscopy has been developed in the form of silicon nanotips, by electron cyclotron resonance plasma chemical vapor deposition, with apex diameters of ∼2 nm, lengths of 1000 nm, and densities of 1011/cm2.
Journal ArticleDOI
Design for approaching Cicada-wing reflectance in low- and high-index biomimetic nanostructures.
Yi Fan Huang,Yi-Jun Jen,Li-Chyong Chen,Kuei-Hsien Chen,Kuei-Hsien Chen,Surojit Chattopadhyay +5 more
TL;DR: Design parameters of spacing/wavelength and length/spacing fitted into a finite difference time domain model could simulate the experimental reflectance values observed in real silicon and germanium or in model silica and indium tin oxide nanotip arrays.
