Researchers have developed a capacitor with a metal-insulator-semiconductor diode structure that is tunable by illumination. The capacitor, which features embedded metal nanoparticles, is similar to a metal-insulator-metal diode, except the capacitance of the new device depends on illumination and exhibits a strong frequency dispersion, allowing for a high degree of tunability. This capacitor may enhance wireless capability for information processing, sensing and telecommunications.
