This scanning electron microscope image shows an indium arsenide (InAs) nanowire field-effect transistor.
Semiconductor nanowires such as those of indium arsenide (InAs) offer exciting possibilities for the electronic systems of the future because of the unique possibilities they offer for controlling fundamental properties during generation. A wide range of nanowire-based devices and systems, including transistors, circuits, light emitters, and sensors, have already been explored. Nanowire field-effect transistors have been of particular interest as vehicles for the investigation of basic carrier-transport behavior and as the heart of new generations of high-performance electronic devices.
• SIZE: The nanowire at center is about 5 µm long.
• IMAGING TOOL: Scanning electron microscope
- Nanometer-sized things are very small, and often behave differently than larger things do.
- Nanoscience, nanotechnology, and nanoengineering lead to new knowledge and innovations that weren't possible before.
