Phononic breakthrough paves the way for compact, high-efficiency chips and enhanced quantum computing capabilities
One of the technological hurdles limiting the future of wireless technology is the reliance on bulky, power-hungry radio frequency processors. These processors require an unwieldy blend of piezoelectric- and transistor-based components, which add bulk and sap valuable energy. But a promising study published in Nature Materials offers a potential solution in phononics, a field of study that harnesses…
