Transistors have been miniaturized for the past 50 years, but we've reached the point where they can't continue to be scaled any further. In Applied Physics Letters, researchers review negative capacitance field-effect transistors, a new device concept that suggests traditional transistors can be made much more efficient by simply adding a thin layer of ferroelectric material. If it works, the same chip could compute far more, yet require less frequent charging of its battery.
Researchers at the University of Washington have developed a robotic system that can feed people who need someone to help them eat.
Working together, researchers at the University of Sydney and UNSW have overcome a fundamental hurdle to building quantum computers in silicon.
Researchers at the Joint Quantum Institute have implemented an experimental test for quantum scrambling, a chaotic shuffling of the information stored among a collection of quantum particles. Their experiments on a group of seven atomic ions demonstrate a new way to distinguish between scrambling and true information loss. The protocol may one day help verify the calculations of quantum computers, which harness the rules of quantum physics to process information in novel ways.
Electric currents drive all our electronic devices. The emerging field of spintronics looks to replace electric currents with what are known as spin currents. Researchers from the University of Tokyo have made a breakthrough in this area. Their discovery of the magnetic spin Hall effect could lead to low-power, high-speed and high-capacity devices. They have created sample devices which can further research into potential applications.
A technology that has maximized space intensity by eliminating color filter from an image sensor has been developed. The National Research Foundation of Korea (Chairman Jung Hye Rho) announced that DGIST Professor Dae Sung Chung's research team developed a color filter-free full-color image sensor using an interferometer electrode.
DGIST Professor Jae Eun Jang's team, plasmonic nano structure developed a technology that generates colorless and transparent biomaterials. Will contribute to biomaterial detection for brain disease research & treatment.
For the first time researchers have demonstrated a new way to perform functions essential to future computation three orders of magnitude faster than current commercial devices. The team lead by Associate Professor Shinobu Ohya, created a nanoscale spintronic semiconductor device that can partially switch between specific magnetic states trillions of times a second (terahertz -- THz), far beyond frequencies of devices at present.
A research team led by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has created a nanoscale 'playground' on a chip that simulates the formation of exotic magnetic particles called 'monopoles.' The study could unlock the secrets to ever-smaller, more powerful memory devices, microelectronics, and next-generation hard drives that employ the power of magnetic spin to store data.
MIT's new mini cheetah robot is springy and light on its feet, with a range of motion that rivals a champion gymnast. The four-legged powerpack can bend and swing its legs wide, enabling it to walk either right-side up or upside down. The robot can also trot over uneven terrain about twice as fast as an average person's walking speed.
