nanoscale semiconductors

How are Nanoscale Semiconductors Fabricated?

There are several methods to fabricate nanoscale semiconductors, including:
1. Top-Down Approach: This involves the miniaturization of bulk materials using techniques like lithography, etching, and molecular beam epitaxy.
2. Bottom-Up Approach: This involves building up structures atom by atom or molecule by molecule through processes like chemical vapor deposition (CVD) and sol-gel synthesis.
Each method has its advantages and limitations, and the choice depends on the desired properties and applications of the nanoscale semiconductors.
