One of the problems that could constitute an issue in the wide-scale use of graphene sheets in the new generation of circuits and electronic devices concerns ripples, which are similar to the ones exhibited by a plastic wrap tightly pulled over a clamped edge. And the need to use the carbon compound will be very compelling in the future, when taking into account its amazing physical and chemical properties, its atom-thick structure, its planar geometry, its high current-carrying capacity and thermal conductivity.The ripples that occur in its structure have the ability to drastically alter its properties, and the problem is that not all of these modifications are good. That is to say, it would be a lot better for researchers if they could trigger the ripples themselves, in a controlled manner that would ensure only the desired modifications are caused. This would ensure a higher level of sophistication for future nanoscale devices and electronics, scientists believe.As such,!
researchers from the University of California in Riverside (UCR) report in the July 26th issue of the journal Nature Nanotechnology that they managed to observe the first successful and controlled man-made ripple in graphene, stretching one or two dimensions. Expert Chun Ning (Jeanie) Lau explains that sim...
