A Northwestern University research team used inverse design principles and a 3-D printer to create highly efficient broadband metadevices at millimeter-wave frequencies that could prove revolutionary for consumer products, defense, and telecommunications.
Researchers at have designed and fabricated the world's smallest electro-optic modulator, which could mean major reductions in energy used by data centers and supercomputers.
Researchers have, for the first time, used a material's persistent photoconductivity to stimulate neurotype cells. The technique, which is relatively simple, should facilitate future research on using charge to influence cellular behavior.
Extremely fine porous structures with tiny holes -- resembling a kind of sponge at nano level -- can be generated in semiconductors. This opens up new possibilities for the realization of tiny sensors or unusual optical and electronic components. There have already been experiments in this area with porous structures made from silicon. Now, researchers at TU Wien have succeeded in developing a method for the controlled manufacture of porous silicon carbide.
Fine tuning the composition of nitride alloys can further the development of optical and electronic interface devices.
Illinois researchers have demonstrated that sound waves can be used to produce ultraminiature optical diodes that are tiny enough to fit onto a computer chip. These devices, called optical isolators, may help solve major data capacity and system size challenges for photonic integrated circuits, the light-based equivalent of electronic circuits, which are used for computing and communications.
One of the big challenges in computer architecture is integrating storage, memory and processing in one unit. This would make computers faster and more energy efficient. University of Groningen physicists have taken a big step towards this goal by combining a niobium doped strontium titanate (SrTiO3) semiconductor with ferromagnetic cobalt. At the interface, this creates a spin-memristor with storage abilities, paving the way for neuromorphic computing architectures. The results were published in Scientific Reports.
Researchers at the ARC Centre of Excellence in Exciton Science have made an important discovery with significant implications for the future of solar cell material design.
MIT researchers have developed hardware that uses electric fields to move droplets of chemical or biological solutions around a surface, mixing them in ways that could be used to test thousands of reactions in parallel.
Scientists at the National Institute of Standards and Technology have now unveiled the long-mysterious inner workings of these semiconductor elements, which can act like the short-term memory of nerve cells.
