GaN power IC features optimised half-bridge design
A provider of highly integrated power management, AC/DC power conversion, Solid State Lighting (SSL) and Bluetooth low energy technology, Dialog Semiconductor, have announced it is demonstrating its first Gallium Nitride (GaN) power IC product offering, using Taiwan Semiconductor Manufacturing Corporation’s (TSMCs) 650V GaN-on-Silicon process technology.
Thin plastic membrane allows for rapid recharging
Researchers have designed a thin plastic membrane that stops rechargeable batteries from discharging when not in use and allows for rapid recharging.The patent-pending technology controls how charge flows inside a battery, and was inspired by how living cell membranes transport proteins in the body. It could find applications in high powered "supercapacitors" for electric cars and even help prevent the kinds of fires that plagued some models of h...
Peculiarity of material's energy states
If one looked deep into three different solids using a super-microscope, one would, in principle, always see the same thing: atomic nuclei arranged in a crystal lattice and electrons, of which some orbit the atomic nuclei and others criss-cross the entire crystal lattice. Nevertheless, those three materials might behave very differently when an electric voltage is applied to them.
A step towards sulfur-based organic semiconductors
Thiophene-fused polycyclic aromatic hydrocarbons (PAHs) are known to be useful as organic semiconductors due to their high charge transport properties. Scientists at Nagoya University have developed a short route to form various thiophene-fused PAHs by simply heating mono-functionalised PAHs with sulfur. This method is expected to contribute towards the efficient development of novel thiophene-based electronic materials.
Optocouplers support satellites, spacecraft, and planetary rovers
A global provider of engineered electronics for performance critical applications,TT Electronics has announced the market introduction of its HCC100x series of radiation tolerant optocouplers. The devices are ideal for the isolation of electrical circuits within high-radiation deep spaceflight applications, including satellites, launch vehicles, space craft, and planetary rovers.
Manufacturing method squeezes more onto limited wafer space
Computer chip makers continuously strive to pack more transistors in less space, yet as the size of those transistors approaches the atomic scale, there are physical limits on how small they are able to make the patterns for the circuitry.
Smartkem expands presence to support flexible display roll-out in Asia
The UK based developer of the truFLEX semiconductor platform for the manufacture of flexible displays and electronics, Smartkem, has made significant investments to support company expansion and the roll-out of its technology platform with display manufacturers in Asia.
The world’s smallest insulated & controlled 9W DC/DC converter
Pewatron AG is launching the world’s smallest insulated and controlled DC/DC converter in the 9W class – the PDL09 range from P-DUKE Power Mate Technology.The PDL09 converter is housed in a small, flat SIP-8 miniature package, measuring just 21.8 x 9.1 x 11.2 mm. But with a power density of up to 66W per cubic inch, it sets a record level in the market, exceeding the levels of the similarly sized PDL06 and standard commercial models b...
Master reference oscillators used in satellite programme
Microsemi Corporation has announced the company was chosen to supply its master reference oscillator for the US Air Force’s Space Based Infrared System (SBIRS) satellite programme for which Lockheed Martin is the prime contractor.
Controlling the electrical current in ultra-thin material
By modifying the composition of ultra-thin layers of dissimilar metal oxides that do not normally conduct electricity, scientists demonstrated how to generate and control an electrical current at the junction where the layers meet. The team made significant advances in one method used to characterise these materials. This work represents a major advance in the field of thin-film engineering.
