Created a diode from a single molecule
Scientists at the University of Barcelona have developed a diode consisting of a single molecule of 1 nm with a high coefficient of rectification current.
Modern technologies have approached the physical limit in reducing the electronic components. According to Ismael Díez-pérez, Director of the project on creation of miniature diodes, "in order to advance to the next level of miniaturization, we have to use as the active components of the circuits of individual molecules."
Scientists, who published their findings in the journal Nature Communications, used organic molecules sandwiched between two nanoelectrodes connected in a single chain with a length of less than 1 nm. The resulting diode from a single molecule is superior to the other in the miniature and brightness. "This approach allows us to collect thousands of billions of tiny diodes on a silicon chip," says Diez-Perez.
The invention of Spanish scientists, like any diode, allows current to flow in one direction, while the ratio of the current rectifying exceed 4000 when using alloyed silicon. These figures are comparable in efficiency with modern diodes are much larger.
Now a team of scientists working to achieve even higher ratios of current rectifying and improving the life of these monomolecular chains, which brings us closer to the development of monomolecular devices.
Hard drive that can store information just one atom, was designed by the company IBM. With this technology you can save the entire iTunes music collection (35 million songs) on a disk the size of a credit card. However, to the practical application of this technology is still far — the system requires a tunneling electron microscope cooled by nitrogen, and vacuum. published
