A 3 dimensional (3D) version of graphene, the 2 dimensional (2D) sheets of carbon through which electrons race at many times the speed as they move through silicon has been discovered.  The discovery is the first experimental confirmation of 3D Dirac fermions in the interior or bulk of a material, a novel state that was […]

Since the transistor replaced the vacuum tube about sixty years ago an ever-growing avalanche of electronics has enriched lives.  While the thought about one’s power blocks and power supplies doesn’t seem like much in a home, everyone plus the support in businesses, governments and the data centers of the internet and cloud sum up to […]
