Dutch development component for phones of single molecule
Several teams of Dutch universities have designed a molecule that functions as a resonant tunneling device, a component operating at radio frequencies and used inter alia for parts of mobile phones and WiFi devices.
The molecule is the result of research by Delft University of Technology, the University of Groningen and the FOM Foundation. According to the researchers, it is the first time that a resonant tunneling device at this scale was designed, and these components are typically larger, more complex and composed of multiple materials. “This is also the ultimate limit for reducing the current electronic components such as diodes, transistors, and so-called resonant tunneling devices.”, The Foundation for Fundamental Research on Matter known.
Resonant tunneling devices are used to amplify electrical signals. Including GSM and Wi-Fi signals They make use of the effect that an increase in the applied voltage leads to a decrease of the electric current runs through them, in other words a negative differential conductance. The researchers show that this negative differential conductance is strongly present in the respective molecule and, moreover, is to control the conduction by pulling. To the molecule They do this by differentiating between the two electrodes to which the molecule is attached the distance.
According to the researchers, the invention was an interesting step in the further miniaturization of electronic components. For example, the design can be used for the design of molecular diodes. Scientists publish the details in the latest edition of the scientific journal Nature Nanotechnology.Viewing:-207
