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

Smokestack metrology The National Institute of Standards and Technology (NIST) has nearly completed the construction of one of the world's more unusual measurement systems. The organization is devising a 50-meter horizontal smokestack at its campus in Gaithersburg, Md. The new facility will accurately determine the amount of gases discharged from smokestacks at coal-fired power plants and o... » read more

28nm brain chips DARPA-funded researchers have developed a 28nm chip that mimics the brain. The low-power chip is inspired by the neuronal structure of the brain. Designed by researchers at IBM under DARPA’s Systems of Neuromorphic Adaptive Plastic Scalable Electronics (SyNAPSE) program, the chip consists of 5.4 billion transistors. Built on Samsung’s 28nm foundry process, the chip has ... » read more

Measuring hydrogen fuel for cars The use of fuel cells to power cars and buses is still in its infancy. Fuel cell vehicles are electric-based systems powered by hydrogen. A fuel cell uses a certain type of proton exchange membrane (PEM). The PEM fuel cells are stacked together to form a fuel cell stack. All told, fuel cell systems are about 60% efficient, or roughly two to three times more ... » read more

World’s thinnest TFTs The U.S. Department of Energy’s Argonne National Laboratory has devised the world’s thinnest flexible, 2D thin-film transistors (TFTs). The transistors are just 10 atomic layers thick. TFTs are typically used in screens and displays. In the lab, Argonne researchers fabricated the TFTs on both a conventional silicon platform and a flexible substrate. [caption i... » read more

Fishy Robots National University of Singapore (NUS) has developed a robotic fish that mimics the movements of a carp—a technology that could pave the way for more efficient autonomous underwater vehicles. This robot is classified as an autonomous underwater vehicle (AUV). Applications include military, pipeline leakage detection, and the laying of communication cable. The robot could be u... » read more
