Flexible Phase Change Materials for Electrically‐Tuned Active Absorbers

Phase change materials (PCMs), such as GeSbTe (GST) alloys and vanadium dioxide (VO2), play an important role in dynamically tunable optical metadevices. However, the PCMs usually require high thermal annealing temperatures above 700 K, but most flexible metadevices can only work below 500 K owing t...
