    Single transistor neurons and synapses fabricated using a standard silicon CMOS process. They are co-integrated on the same 8-inch wafer

    KAIST researchers fabricated a brain-inspired highly scalable neuromorphic hardware by co-integrating single transistor neurons and synapses. Using standard silicon complementary metal-oxide-semiconductor (CMOS) technology, the neuromorphic hardware is expected to reduce chip cost and simplify fabrication procedures.

    The research team led by Yang-Kyu Choi and Sung-Yool Choi produced a neurons and synapses based on single transistor for highly scalable neuromorphic hardware and showed the ability to recognize text and face images. This research was featured in Science Advances on August 4.

    Neuromorphic hardware has attracted a great deal of atten...

    Wister Huang, a final-year PhD student in Electrical Engineering; Professor Andrew Dzurak; and Dr Henry Yang, a senior research fellow.

    The research, carried out by Professor Andrew Dzurak’s team in UNSW Engineering, was published in the journal Nature. The experiments were performed by Wister Huang, a final-year PhD student in Electrical Engineering, and Dr Henry Yang, a senior research fellow at UNSW.

    “All quantum computations can be made up of one-qubit operations and two-qubit operations – they’re the central building blocks of quantum computing,” says Professor Dzurak.

    “Once you’ve got those, you can perform any computation you want – but the accuracy of both operations needs to be very high.”

    In 2015 Dzurak’s team was the first to build a quantum logic gate in silicon,...

    An international team has developed inks made of graphene-like materials for inkjet printing. New black phosphorus inks are compatible with conventional inkjet printing techniques for optoelectronics and photonics. Black phosphorus is a particularly interesting post-graphene nanomaterial for next generation devices. Yet despite remarkable performance in the lab, practical real-world exploitation of this material has been hindered by complex material fabrication and its poor environmental stability.

    “Our inkjet printing demonstration makes possible for...
