Manufacturing Bits: Aug. 21


World’s smallest transistor The Karlsruhe Institute of Technology (KIT) has developed what researchers say is the world’s smallest transistor. Researchers have devised a single-atom transistor. The transistor switches an electrical current via a single atom, which resides in a gel electrolyte. The device also works at room temperature. While others have developed single-atom transist... » read more

Too Many, Too Few Rare Earths


A team from Japan recently made a major discovery—they found massive deposits of rare earths on the ocean floor off the coast of Japan. The team of Waseda University, the University of Tokyo and the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) found a deposit that equates to 16 million tons of rare earths. Rare earths are a group of critical materials used in various ele... » read more

Searching For The Next Power Transistor


For decades, the industry has relied on various power semiconductors to control and convert electrical power in an efficient manner. Power semis are ubiquitous, as they are found in adapters, appliances, cars, elevators, switching power supplies, power grids and other systems. But today’s silicon-based power semiconductor transistor technologies, such as IGBTs, MOSFETs and thyristors, are ... » read more
