Future display panels and solar cells can be possible with nanokristallen of semiconductors are made. A technique to make patterns with such crystals on a substrate to make that possible.
Researchers at the School of Science at the Massachusetts Institute of Technology developed their method to nanokristallen on a surface using lithographic techniques. The scientists can make their technique to various materials for nanokristallen apply, depending on the desired properties of the resulting structures. According to the MIT’ers would be their method, result in a film nanokristallen on a substrate without defects in the structure. Similar movies show still defects in the structure, causing the electrical conductivity is less.
With the lithographic produced a crystal structure, in which an electron beam was used to create the desired patterns to form, the researchers have defect-free thin films in the hands. The resolution of the structures amounts to approximately 30nm and the properties of the films depend on the size of the individual nanokristallen. So give crystals of the same material, but different size and different colors when they are under tension.
The nanokristallen could be used in display technology, in which crystals of different dimensions for the desired kleurpixels sure, but they can also be as photovoltaic cells in solar cells are used. Furthermore, the crystals as sensors for organic molecules, may serve and be used for fundamental materiaalwetenschappelijke to answer questions.
