How to Make Graphene at Home for Fun

Video provides a good description and nice do-it-yourself experiments with the latest wonder material: graphene

I came across the video below from the blog Frogheart and considering the recent Nobel Prize for Physics and the near daily reports on graphene within the pages of Spectrum alone, I thought it worth posting here.

The video provides a demonstration in a very rough way for how one could manage to isolate a single layer of graphite to create graphene.

The presenter, Dr. Jonathan Hare, manages to bring up the issue of the speed at which electrons travel through graphene to discuss relativistic quantum mechanics and Dirac particles and still manages to make it accessible for a general audience.

Nice piece of work and will lead me to check out the video’s producers Vega Science Trust for more material.

3D-Stacked CMOS Takes Moore’s Law to New Heights

When transistors can’t get any smaller, the only direction is up

Perhaps the most far-reaching technological achievement over the last 50 years has been the steady march toward ever smaller transistors, fitting them more tightly together, and reducing their power consumption. And yet, ever since the two of us started our careers at Intel more than 20 years ago, we’ve been hearing the alarms that the descent into the infinitesimal was about to end. Yet year after year, brilliant new innovations continue to propel the semiconductor industry further.

Along this journey, we engineers had to change the transistor’s architecture as we continued to scale down area and power consumption while boosting performance. The “planar” transistor designs that took us through the last half of the 20th century gave way to 3D fin-shaped devices by the first half of the 2010s. Now, these too have an end date in sight, with a new gate-all-around (GAA) structure rolling into production soon. But we have to look even further ahead because our ability to scale down even this new transistor architecture, which we call RibbonFET, has its limits.
