Mechanics of Silicon Nanowires: Size-Dependent Elasticity From First Principles

We review our recent work on the mechanics of silicon nanowires based on first-principles density functional theory (DFT) calculations. We focus especially on the size dependence of the Young’s modulus, but also comment on the size dependence of the residual stress and the equilibrium length of the hydrogen-passivated Si nanowires. We compare these results to prior results from classical molecu...

Localized Growth and Characterization of Silicon Nanowires

This thesis deals with the epitaxial growth and characterization of silicon nanowires, because these nanostructures have recently been incorporated in functional devices with success, but a reproducible use requires a deeper understanding of their physical properties. As the growth proceeds through the incorporation of Si species into catalyst particles, we first investigated the formation of g...

Mechanical properties of silicon carbide nanowires: effect of size-dependent defect density.

This paper reports quantitative mechanical characterization of silicon carbide (SiC) nanowires (NWs) via in situ tensile tests inside scanning electron microscopy using a microelectromechanical system. The NWs are synthesized using the vapor-liquid-solid process with growth direction of ⟨111⟩. They consist of three types of structures, pure face-centered cubic (3C) structure, 3C structure with ...

Structural Characterization of Amorphous Silicon

The structure of amorphous silicon in its pure and hydrogenated form has attracted wide interest over the last five decades. This substantial interest is twofold. Firstly, amorphous silicon is a technologically highly significant material with many applications such as photovoltaic cells or thin-film transistors. Secondly, physically it is a fundamentally interesting material which has been reg...

Surface charge sensitivity of silicon nanowires: size dependence.

Silicon nanowires of different widths were fabricated in silicon on insulator (SOI) material using conventional process technology combined with electron-beam lithography. The aim was to analyze the size dependence of the sensitivity of such nanowires for biomolecule detection and for other sensor applications. Results from electrical characterization of the nanowires show a threshold voltage i...
