Using the nano origami technique, small microchips could be made from graphene and other two-dimensional materials. Thanks to the physicists at the University of Sussex for the discovery.
Graphene is one of the two-dimensional materials and is made up of a layer of carbon atoms. This material is strong and they are fine conductors of electricity, Also they are more prone to wrinkles. The influence of the wrinkling effect on the electronic properties of graphene has not yet been understood fully.
By developing kinks in the graphene structure the researchers have made the nano-based material act like a transistor. They have also shown that when the graphene strip is wrinkled, it could behave like a microchip. This microchip is found to be 100 times smaller. They have made use of atomic force microscopy to detect the effects of wrinkles.
Prof Alan Dalton of the School of Mathematical and Physics Sciences at the University of Sussex said: " We developed mechanically kinks in the graphene layer, it is like nano origami. With the use of nanomaterials, computer chips could be made smaller and faster. Today the semiconductor technology is limiting computer manufacturers. The straintronics technology using nanomaterials provides more space for chips inside any device. What is required is to speed the computers by wrinkling graphene "
Dr. Manoj Tripathi, Research Fellow in Nanostructured Materials at the University of Sussex and lead author on the paper, said: Without adding any foreign materials, we have created structures from graphene and other 2D materials by making kinks to the 2D structure. Through this, we could form a smart transistor or a logic gate"
