Hiroshima University and Mie Fujitsu Semiconductor Limited (MIFS) today announced the development of a low-power millimeter-wave amplifier that feeds on 0.5 V power supply and covers the frequency range from 80 GHz to 106 GHz. It was fabricated using MIFS’s Deeply Depleted Channel (DDC) technology. This is the first W-band (75−110 GHz) amplifier that can […]
Terahertz Wireless Could Make Spaceborne Satellite Links as Fast as Fiber-Optic Links
Hiroshima University, National Institute of Information and Communications Technology, and Panasonic Corporation announced the development of a terahertz (THz) transmitter capable of transmitting digital data at a rate exceeding 100 gigabits (= 0.1 terabit) per second over a single channel using the 300-GHz band. This technology enables data rates 10 times or more faster than […]
Power Up When the Temperature is Down
Transporting power sources in the coldest places may be easier with a new re-chargeable, non-metallic battery from Japan. This “eco battery” could provide portable sources of power in environments like refrigerated factories or extreme winter environments. Chemists from Hiroshima University developed a new synthesis method for organic radical batteries that are re-chargeable and continue to […]
Eliminating ‘Springback’ To Help Make Environmentally Friendly Cars
Manufacturing safe and lightweight cars that emit less carbon dioxide could become easier thanks to a clever new engineering development from researchers at Hiroshima University. Dr. Komgrit Lawanwong and colleagues have engineered some subtle refinements to metal forming techniques that allowed them to prevent a difficult problem called “springback,” which plagues the process of bending […]
Next-Gen Illumination Using Silicon Quantum Dot-Based White-Blue LED
A Si quantum dot (QD)-based hybrid inorganic/organic light-emitting diode (LED) that exhibits white-blue electroluminescence has been fabricated by Professor Ken-ichi SAITOW (Natural Science Center for Basic Research and Development, Hiroshima University), Graduate student Yunzi XIN (Graduate School of Science, Hiroshima University), and their collaborators. A hybrid LED is expected to be a next-generation illumination device […]
