Silicon is a naturally occurring material commonly used as a semiconductor in electronic devices; however, researchers have exhausted the potential of devices with semiconductors made of silicon only. These devices are limited by silicon’s carrier mobility — the speed at which a charge moves through the material — and indirect bandgap, which limits its ability to release and absorb light.
