“…Semiconductor Si nanowire network lms were synthesized through gold-catalytic vapour-liquidsolid approach. 35,36 Initially, 50 nm Au nanoparticles, which served as the catalyst for nucleation and growth of Si nanowires, were dispersed on SiO 2 /Si substrate. Si nanowires were grown at 450 C for 1.5 h with SiH 4 as the silicon reactant and H 2 as the carrier gas.…”

Slippery surface based on lubricant infused hierarchical silicon nanowire film

et al. 2017

Nanowire thin films exhibiting superhydrophobicity or even superomniphobicity can protect themselves from liquid contamination. However, high contact angle of these thin films with liquid droplets limits the interfacial area between liquids and nanowire network, which is unfavorable for applications such as sensing suspended liquid droplets. In this study, slippery surface based on lubricant infused hierarchical Si nanowire film was developed, which provided low contact angle with liquid droplet, while possessing liquid repellent properties upon slight tilting. Si nanowire films were fabricated through chemical vapor deposition and were further branched with ZnO nanospikes for enhanced immobilization of lubricant.These hierarchical nanowire films were functionalized to enhance their superhydrophobicity and were further infused with perfluorinated lubricant to produce slippery surface. These infused slippery surfaces exhibited low contact angles with blood and corn oil along with high repellency towards these liquids.This study offers a promising approach for creating nanowire films that avoid liquid contamination.

Transparent and flexible materials are desired for the construction of photoelectric multifunctional integrated devices and portable electronics. Herein, 2H-SiC nanowires are assembled into a flexible, transparent, self-standing nanowire fabric (FTS-NWsF). The as-synthesized ultralong nanowires form high-quality crystals with a few stacking faults. The optical transmission spectra reveal that FTS-NWsF absorbs most incident 200-400 nm light, but remains transparent to visible light. A polydimethylsiloxane (PDMS)-SiC fabric-PDMS sandwich film device exhibits stable electrical output even when repeatedly stretched by up to 50%. Unlike previous SiC nanowires in which stacking faults are prevalent, the transparent, stretchable SiC fabric shows considerable photoelectric activity and exhibits a rapid photoresponse (rise and decay time < 30 ms) to 340-400 nm light, covering most of the UV-A spectral region. These advances represent significant progress in the design of functional optoelectronic SiC nanowires and transparent and stretchable optoelectronic systems.

“…Notably, this procedure requires simple and crude lithographic techniques and wet chemical methods, while no electrical or mechanical forces have been applied in order to align the NFs, unlike other alignment methods. [23][24][25] In addition, the resulting nanojunction device is compact, requires no feedback system and is stable under ambient conditions, which makes it suitable for integration in complex measurement systems. The junction by itself is stable in various chemical and biological conditions, thus enabling measurements at variant conditions.…”

Self-formed nanogap junctions for electronic detection and characterization of molecules and quantum dots

et al. 2017

Fabrication of self-forming nanojunction devices is demonstrated using positioning of nanofloret-like building blocks that serve as self-assembled electrodes. A main feature of the device is a self-formed nanogap bridging between the nanofloret (NF) hybrid nanostructures (HNS) and a macroscopic counterelectrode. When nanostructures are introduced to the device they provide facile bridging across the nanostructure. This strategy is used to demonstrate electronic measurements across molecules and nanoparticles. Connecting the NF nanojunction to the micro-, and macro-scales is achieved by applying standard, robust, optical lithography. In addition, the devices are operable at ambient conditions and in solvent environments, where introducing molecules to the device results in a prominent change in the conductance characteristics. Furthermore, introduction of quantum dots results in the mapping of their band structure at ambient conditions. Our results provide a proof-of-concept of large scale self-forming nanogap device platform realized using simple fabrication tools. Such a technology can be used for molecular detectors, as a potential building block for molecular electronics, or as a platform for fundamental research.
