Thin Film Polycrystalline Silicon Nanowire Biosensors [PDF]

Nano Letters, 2012
Polysilicon nanowire biosensors have been fabricated using a top-down process and were used to determine the binding constant of two inflammatory biomarkers. A very low cost nanofabrication process was developed, based on simple and mature photolithography, thin film technology, and plasma etching, enabling an easy route to mass manufacture.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Freeform Fabrication of Layered Halide Perovskite Nanowire Heterojunctions

Advanced Materials, EarlyView.
‘All‐at‐once’ freeform fabrication of layered perovskite nanowire heterojunctions is realized by 3D printing employing meniscus‐guided crystallization. The integration of nanoscale additive manufacturing with layered halide perovskites will provide a versatile platform to freely design and realize highly stable perovskite‐based optoelectronic ...

Fabrication of Silicon Nanowires and Transistors with Silicon Nanowire-Channels

Journal of the Vacuum Society of Japan, 2009
Si nanowires (SiNWs) were synthesized by gold (Au)-catalyzed chemical vapor deposition (CVD). To control the morphology of SiNWs, the growth parameters were systematically changed and they were studied by transmission and scanning electron microscopes and Raman spectroscopy.

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Optical trapping and manipulation of nanowires using multi-hotspot dielectric nanononamers

AIP Advances, 2022
Semiconductor nanowires have demonstrated great potential in all-photonic integrated circuit applications. However, the development of a controllable multidimensional nanowire assembly technique is still arguably in its infancy.

Channel-Width Dependent Enhancement in Nanoscale Field Effect Transistor [PDF]

, 2008
We report the observation of channel-width dependent enhancement in nanoscale field effect transistors containing lithographically-patterned silicon nanowires as the conduction channel. These devices behave as conventional metal-oxide-semiconductor field-

Monolithic Fabrication of Silicon Nanowires Bridging Thick Silicon Structures [PDF]

IEEE Nanotechnology Express, 2015
A monolithic process is developed for the fabrication of Si nanowires within thick Si substrates. A combination of anisotropic etch and sidewall passivation is utilized to protect and release Si lines during the subsequent deep etch. An etch depth of $10~\mu \text{m}$ is demonstrated with a future prospect for 50 $\mu \text{m}$ opening up ...
