Chapter Content
Transistors and memory devices are being scaled down using carbon nanotubes, graphene, and molecular electronics to create faster and more efficient circuits.
Detailed Explanation
Nanoelectronics focuses on miniaturizing electronic components to improve their performance and efficiency. This involves using advanced materials like carbon nanotubes (which are extremely strong and conductive), graphene (a single layer of carbon atoms with exceptional electrical properties), and molecular electronics (which utilize individual molecules in electronic designs). By reducing the size of transistors and memory devices, we can fit more of these components onto a single chip, resulting in faster processing speeds and lower energy consumption.
