Journal ArticleDOI
Deep and tapered silicon photonic crystals for achieving anti-reflection and enhanced absorption.
TL;DR: From the measurements using a spectrophotometer and an angle-variable spectroscopic ellipsometer, the sub-wavelength periodic structure can provide a broad and angular-independent antireflective window in the visible region for the TE-polarized light.
Journal ArticleDOI
Antireflective silicon surface with vertical-aligned silicon nanowires realized by simple wet chemical etching processes
TL;DR: The SiNWs fabricated by the proposed technique can provide 92% of solar weighted absorption with about 720 nm long wires because of the resultant effective graded index and enhanced multiple optical scattering from the random SiNW lengths and tapered wires after KOH etching.
Journal ArticleDOI
Effective Synthesis of Highly Oxidized Graphene Oxide That Enables Wafer-scale Nanopatterning: Preformed Acidic Oxidizing Medium Approach.
Chun-Hu Chen,Shin Hu,Jyun-Fu Shih,Chang-Ying Yang,Yun-Wen Luo,Ren-Huai Jhang,Chao-Ming Chiang,Yung-Jr Hung +7 more
TL;DR: The combination of the facile and potent PAOM approach with the wafer-scale patterning technique may realize the goal for massive throughput graphene nanoelectronics.
Journal ArticleDOI
Fabrication of Highly Ordered Silicon Nanowire Arrays With Controllable Sidewall Profiles for Achieving Low-Surface Reflection
TL;DR: In this article, a single-step deep-reactive-ion etching (SDRIE) is used to transfer the holography patterned photoresist template to silicon or silicon-on-insulator substrates.
Journal ArticleDOI
Transformation into nanocrystalline or amorphous materials in Zr–X binary systems using ARB route
TL;DR: In this paper, the gradual evolution of coarse grains during room temperature accumulative roll bonding into nanoscaled extra-fine grains or eventually amorphous phase in the Zr-Ti, Zr−Ni, and Zr•Cu binary systems is examined.
