What are Nanotech Systems?
Nanotech systems refer to devices and mechanisms that operate at the nanoscale, typically between 1 and 100 nanometers. These systems leverage the unique properties of materials at this scale, such as increased surface area, quantum effects, and enhanced reactivity, to perform tasks that are difficult or impossible for larger-scale systems.
How are Nanotech Systems Fabricated?
There are two primary approaches to fabricating nanotech systems:
top-down and
bottom-up. In the top-down approach, larger materials are reduced to the nanoscale through methods like lithography and etching. The bottom-up approach involves assembling nanostructures atom by atom or molecule by molecule, often using chemical vapor deposition or self-assembly techniques.
