Question

Quizplus · Accepted Answer

Top-down approaches to nanofabrication involve starting with a larger structure and then etching, milling, or machining it down to the desired nanoscale dimensions. Electron-beam lithography, micro-imprint lithography, and X-ray lithography are all techniques that fit this description, as they involve patterning and shaping materials from the top down to create nanostructures.
