(ANI): The theoretical work done by Abhishek Singh Evgeni Penev and Boris Yakobson, three Rice University opens a new world of possibilities for a class of increasingly smaller devices of nanoelectronics depends on the semiconducting properties highly controllable quantum dots, especially in the field of advanced optics.
graphane graphene is simply modified by hydrogen atoms added to both sides of the fabric which provide it with insulating capacity. Although it is still technically a single atom thick as graphene, graphane great potential for manipulation of the semiconducting properties of the material.
Quantum dots are crystalline molecules of varying sizes depending on the function, which contain from a few atoms to large quantities of them, and unique ways to interact with light and magnetic fields. Size a quantum dot determines the amount of energy needed to close the circuit, and that makes it adjustable in a precise degree. Quantum dots activated in this way are particularly useful as chemical sensors and solar cells as well as for medical imaging and nano-sized circuits.
Researchers have estimated that removing hydrogen islands on both sides of an array of holes are graphane all the properties of quantum dots.
addition to serving for optical applications, quantum dots can be useful as sensors in a single molecule and may lead to manufacturing tiny transistors or also highly miniaturized semiconductor lasers.
There are still unresolved questions concerning how to prepare ensembles of quantum dots on a sheet of graphane, but the study authors did not consider that there are insurmountable obstacles.
