Phys.org  September 29, 2022 Ions in water move slower than electrons in semiconductors, scientists think the diversity of ionic species with different physical and chemical properties could be harnessed for richer and more diverse information processing. A team of researchers at Harvard University developed a 16 × 16 array of new ionic transistors in an aqueous quinone solution. Each transistor features a concentric ring electrode pair with a disk electrode at the center. The electrodes in the solution provided the basis for the transistor operation. The ring pair electrochemically tunes the local electrolytic concentration to modulate the disk’s Faradaic reaction […]
