This is a scanning electron microscope image of vertical arrays of zinc oxide (ZnO) nanowires on a sapphire substrate.
Zinc oxide (ZnO) is an ideal material for nanoscale optoelectronics, electronics, and biotechnology applications. Numerous ZnO-based devices have already been developed, including nanowire field effect transistors, piezoelectric nanogenerators, optically pumped nanolasers, and biosensors.
• SIZE: The sample displayed in the image is about 10 µm wide.
• 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.
