A three-generation legend in PCBs

  In 1956, when HG Verheul manufactured the first printed circuit boards (PCBs) in South Africa, little could he have imagined that 60 years later the company would have grown to a multi-million rand manufacturer run by his three sons; at one time employing over 100 staff. Now it is nearly time to hand over […]

Improving carbon superlattices for quantum electronics

  Researchers at the Nanoscale Transport Physics Laboratory at the School of Physics, University of the Witwatersrarnd (Wits) have found a technique to improve carbon superlattices for quantum electronic device applications. Superlattices are made up of alternating layers of very thin semiconductors, just a few nanometres thick.These layers are so thin that the physics of […]
