Surface Plasmons in Silicon Nanowires [PDF]
Advanced Photonics Research, 2021 Plasmon resonances (PRs) in metallic nanostructures have been extensively studied, whereas reports on PR in silicon nanowires (Si NWs) are very few, partial, and they refer to structures larger than 100 nm. Discrete resonances in Si NWs with core sizes as small as 30 nm at high resolution are observed.

Porous silicon nanowires [PDF]
Nanoscale, 2011 In this mini-review, we summarize recent progress in the synthesis, properties and applications of a new type of one-dimensional nanostructures-single crystalline porous silicon nanowires. The growth of porous silicon nanowires starting from both p- and n-type Si wafers with a variety of dopant concentrations can be achieved through either one-step or ...

Silicon Nanowires: A Breakthrough for Thermoelectric Applications [PDF]
Materials, 2021 The potentialities of silicon as a starting material for electronic devices are well known and largely exploited, driving the worldwide spreading of integrated circuits. When nanostructured, silicon is also an excellent material for thermoelectric applications, and hence it could give a significant contribution in the fundamental fields of energy micro-

Fluorescent Biosensors Based on Silicon Nanowires [PDF]
Nanomaterials, 2021 Nanostructures are arising as novel biosensing platforms promising to surpass current performance in terms of sensitivity, selectivity, and affordability of standard approaches. However, for several nanosensors, the material and synthesis used make the industrial transfer of such technologies complex.

Electron Mobility in Silicon Nanowires [PDF]
IEEE Transactions On Nanotechnology, 2007 The low-field electron mobility in rectangular silicon nanowire (SiNW) transistors was computed using a self-consistent Poisson-Schrödinger-Monte Carlo solver. The behavior of the phonon-limited and surface-roughness-limited components of the mobility was investigated by decreasing the wire width from 30 nm to 8 nm, the width range capturing a ...

Mechanical Properties of Silicon Nanowires [PDF]
Nanoscale Research Letters, 2009 Abstract Nanowires have been taken much attention as a nanoscale building block, which can perform the excellent mechanical function as an electromechanical device. Here, we have performed atomic force microscope (AFM)-based nanoindentation experiments of silicon nanowires in order to investigate the mechanical properties of silicon nanowires.

Hidden defects in silicon nanowires [PDF]
Nanotechnology, 2011 Recent publications have reported the presence of hexagonal phases in Si nanowires. Most of these reports were based on 'odd' diffraction patterns and HRTEM images—'odd' means that these images and diffraction patterns could not be obtained on perfect silicon crystals in the classical diamond cubic structure.

Silicon Nanowires for Gas Sensing: A Review [PDF]
Nanomaterials, 2020 The unique electronic properties of semiconductor nanowires, in particular silicon nanowires (SiNWs), are attractive for the label-free, real-time, and sensitive detection of various gases. Therefore, over the past two decades, extensive efforts have been made to study the gas sensing function of NWs.
