Nanowire Structure

Nanowires are characterized by their core, shell, surface, and interfaces.
Cores can be made of metals, semiconductors, insulators, and conducting polymers.
Shells and surfaces can be functionalized with various materials.
Nanowires can have diverse morphologies, including straight, bent, branched, core-shell, and hollow structures.

Nanowire Synthesis

Different synthesis methods offer control over nanowire structure.
Common methods include vapor-liquid-solid (VLS) growth, solution-liquid-solid (SLS) growth, chemical vapor deposition (CVD), molecular beam epitaxy (MBE), and electrochemical deposition.

E-beam Lithography (EBL)

A high-resolution patterning technique for microelectronics and nanotechnology.
Uses a focused electron beam to expose a resist material.
The resist material undergoes a chemical change upon exposure to the electron beam.
The scanned electron beam creates a pattern in the resist material.
EBL enables resolutions down to 10 nm or smaller.
A mask is not needed because the pattern is directly written onto the substrate.

EBL Applications

Fabrication of integrated circuits, transistors, and other semiconductor devices in microelectronics.
Creation of nanostructures, such as nanowires, nanotubes, and nanoparticles in nanotechnology.
