(Phys.org)—A pair of researchers with the University of Tokyo has found a way to improve on scanning tunneling microscope (STM) technology where it is now possible to measure electrical conductance at individual sites on ...
It's nearly 50 years since Gordon Moore predicted that the density of transistors on an integrated circuit would double every two years. "Moore's Law" has turned out to be a self-fulfilling prophecy that technologists pushed ...
