Predicting previously unseen phenomena in exotic materials
Discovered just five years ago, topological semimetals are materials with unusual physical properties that could make them useful for future electronics. In the latest issue of Nature Physics, MIT researchers report a new theoretical characterisation of topological semimetals’ electrical properties that accurately describes all known topological semimetals and predicts several new ones.
Light waves might be able to drive future transistors
The electromagnetic waves of light oscillate approximately one million times in a billionth of a second, hence at petahertz frequencies. In principle, future electronics could reach this speed and become 100,000 times faster than current digital electronics.
Industry’s first DMOS FET arrays with 1.5A sink-output drive
Toshiba Electronics Europe has launched a new generation of highly efficient transistor arrays, hailed as the industry’s first with a 1.5A sink-output driver. The TBD62064A and TBD62308A series DMOS FET transistor arrays are available in the same package and pin configurations and provide the same functionality as the older TD62xxxA series, while cutting power losses by about 38%.
Fine tuning phosphorous heterocycle materials for organic electronics
Scientists at Tokyo Institute of Technology have produced airstable 1-aryl 1,3-diphosphacyclobutane-2,4-diyl materials by direct arylation with electron rich aromatic substituents. This method enables the fine tuning of the electronic properties of such phosphorous heterocycles compounds for applications including fabrication of organic electronics and hydrogen fluoride sensors.
SiC and GaN technologies lead the way at PCIM 2016
This year’s PCIM exhibition introduced a whole host of new power products, technologies and applications. Sally Ward-Foxton reports from Nuremberg.This year’s PCIM (power conversion, intelligent motion) exhibition in Nuremberg brought together 436 exhibitors and more than 10,000 visitors from around the world to share the latest in power products, technologies and applications.
'Weak' materials offer advances for electronics
Fundamental research by University of Texas at Dallas physicists may accelerate the drive toward more advanced electronics and more powerful computers. The scientists are investigating materials called topological insulators, whose surface electrical properties are essentially the opposite of the properties inside.
5A gate drive optocouplers features unmatched noise immunity
Broadcom Limited has announced a new generation of 5A gate drive optocoupler devices, the ACPL-352J and ACNW3430, designed for a wide range of industrial applications including motor drives and power inverters. The devices feature superb common mode transient immunity (CMTI) of up to 100kV/μs, preventing erroneous gate driver failures in noisy environments. Both the ACPL-352J and ACNW3430 support up to 5A rail-torail output current, which elim...
1.5kW RF power transistor sets new benchmark
NXP Semiconductors has introduced what it claims to be the most powerful RF transistor in any technology operating at any frequency. Designed to deliver 1.50kW CW at 50V, the MRF1K50H can reduce the number of transistors in high-power RF amplifiers, which helps to reduce amplifier size and BoM.
Engineers discover a gatekeeper for light
Imagine a device that is selectively transparent to various wavelengths of light at one moment, and opaque to them the next, following a minute adjustment. Such a gatekeeper would enable powerful and unique capabilities in a wide range of electronic, optical and other applications, including those that rely on transistors or other components that switch on and off.
