Ordered Ag/Si Nanowires Array: Wide-Range Surface-Enhanced Raman Spectroscopy for Reproducible Biomolecule Detection
Jian-An Huang,Yingqi Zhao,Xuejin Zhang,Lifang He,Tailun Wong,Ying-San Chui,Wenjun Zhang,Shuit-Tong Lee +7 more
TL;DR: Hexagonal-packed silver-coated silicon nanowire arrays as a nanogap-free SERS system with wide-range electric fields and controlled interwire separation are reported, showing that the ordered Ag/SiNW array system may serve as an excellent SERS platform for practical chemical and biological detection.
Journal ArticleDOI
Layer-by-layer-assembled reduced graphene oxide/gold nanoparticle hybrid double-floating-gate structure for low-voltage flexible flash memory.
TL;DR: Developing an appropriate upper-fl oating-gate material with the following properties is necessary for technological applications: i) a suitable work function to set up an energy barrier so a long retention time is obtained; ii) a large area to achieve an accurate spatial distribution on the lower fl oating gate; and iii) a fl attened surface to improve the interface quality between the double fl Oating gate and the dielectric layer.
Journal ArticleDOI
Gas sensors for ammonia detection based on polyaniline-coated multi-wall carbon nanotubes
Lifang He,Lifang He,Yong Jia,Yong Jia,Fanli Meng,Fanli Meng,Minqiang Li,Jinhuai Liu,Jinhuai Liu +8 more
TL;DR: In this paper, a PANI-coated multi-wall carbon nanotubes (PANI-Coated MWNTs) were used to detect ammonia in the range of 0.2-15ppm.
Journal ArticleDOI
In situ nitrogen-doped graphene grown from polydimethylsiloxane by plasma enhanced chemical vapor deposition
Chundong Wang,Yungang Zhou,Yungang Zhou,Lifang He,Tsz-Wai Ng,Guo Hong,Qi Hui Wu,Fei Gao,Chun-Sing Lee,Wenjun Zhang +9 more
TL;DR: A novel method to prepare in situ nitrogen-doped graphene by microwave plasma assisted chemical vapor deposition (CVD) using PDMS (polydimethylsiloxane) as a solid carbon source and first-principles calculations show that the incorporated nitrogen atoms can lead to p-type doping of graphene.
Journal ArticleDOI
Preparation of Porous Tin Oxide Nanotubes Using Carbon Nanotubes as Templates and Their Gas-Sensing Properties
TL;DR: In this paper, the as-prepared porous tin oxide (SnO2) nanotubes exhibited a good response and reversibility to some organic gas, such as ethanol and acetone.
