the components of the nanoelectronics of the future based on graphene

The various research organizations around the world do not make a mistake,  To determine what kind of shape they had to do, the researchers took advantage of advances in the field of transmission electron microscopy in recent years, based on the correction of spherical aberration . In this way, we can increase the resolution of the images obtained with beams of electrons and observe atomic structures with a resolution of less than a nanometer . In this case, it was possible to see the distribution of carbon atoms on the edges of nanoribbons of graphene whose width is the scale of a few nanometers.

The experiment began with determination of their forms as they were driven by weak electric currents and use of low intensity electron beams. By increasing these two intensities, the structure of nanoribbons began to deteriorate. It was then possible to study jointly, as of this evolution, the correlation between the shape of the nanoribbons and their conduction properties while assessing their resistance to degradation in passing a current of a given intensity . It was superior to that of copper nanoribbons. Physicists have been able to follow the details of these changes until their widths are less than one nanometer, that is to say the space be occupied 5 carbon atoms aligned.

Newly acquired knowledge should help researchers design the components of the nanoelectronics of the future based on graphene.
