What are Some Examples of Energy Efficient Nanodevices?
1. Nanoscale Transistors: Traditional silicon-based transistors face limitations in terms of energy efficiency as they shrink in size. Nanoscale transistors made from materials like graphene or CNTs offer lower power consumption and faster switching speeds. 2. Nanogenerators: These devices convert mechanical energy into electrical energy using nanostructured materials. Zinc oxide nanowires, for example, are used in nanogenerators to harvest energy from vibrations and motions. 3. Nanophotonic Devices: Utilizing the principles of nanophotonics, these devices manipulate light at the nanoscale to achieve higher efficiency in applications like LEDs and lasers. Metamaterials can be engineered to enhance the light-matter interaction, leading to lower energy consumption.
