Phase-change materials and correlated oxides gain ground on silicon for top spot in future electronics

By April Gocha / September 30, 2014

Silicon has long reigned supreme in electronics. But the wonder material is quickly approaching its limit in devices that long to be smaller, run faster, and do more—so new emerging materials are quickly entering the race to replace silicon.

New ultrathin VO2 film device perfectly, reproducibly absorbs infrared light

By Eileen De Guire / December 3, 2012

Left: This diagram shows the experimental setup used for measuring the reflectivity of the vanadium-sapphire device. The vanadium oxide layer is only 180 nanometers thick, much thinner than the wavelength of the incident infrared light. Right: At just the right temperature (light blue line), the reflectivity of the device drops almost to zero (99.75% absorbance)…
