FETs are crucial in nanotechnology for several reasons:
1. Scalability: FETs can be scaled down to nanometer dimensions, which is essential for creating more powerful and efficient nanodevices. 2. Low Power Consumption: Due to their high efficiency, FETs are ideal for low-power applications, which is a critical factor in developing sustainable nanotechnology. 3. High-Speed Operation: FETs can operate at very high speeds, making them suitable for advanced computational and communication technologies.
