If computer chips could be built from semiconductors just one atom thick, they could pack far more transistors into a smaller space while using lesspower. So far, however, the technology has been held back by the weakness of “p-type” transistors, which make up half of every modern chip.
In a new study published in Nature, researchers led by Vincent Tung at the University of Tokyo have shown that atom-thin sheets of boron carbon nitride (BCN) could offer a promising solution.
Transistor bottleneck
Today’s chips rely on two types of transistors working in pairs. In “n-type” transistors, electric current is carried by negatively charged electrons...
