The VLS process is widely employed to produce nanowires. It involves the growth of nanowires from a liquid or vapor catalyst, creating well-defined structures.
Hydrothermal synthesis uses a high-temperature, high-pressure aqueous solution to produce nanowires. It’s a versatile method, and the resulting nanowires exhibit excellent crystallinity.
This method utilizes a template, often made of anodized aluminum oxide or porous membranes, to guide the growth of nanowires. The template provides the desired structure and shape.
Physical Vapor Deposition (PVD)
PVD involves the evaporation of material from a solid source to form a vapor that condenses on the substrate, resulting in the growth of nanowires.
Chemical Vapor Deposition (CVD)
CVD utilizes a chemical reaction to deposit a thin film or nanowires on a substrate. It’s a versatile method that allows precise control over the nanowire properties.
Atomic Layer Deposition (ALD)
ALD is a precise method to fabricate nanowires by layering atoms in a controlled manner. It ensures uniform growth and conformal coating.
Anodization is a simple technique where nanowires are grown by applying an electric potential to a metal substrate in an electrolyte solution.
