Description
Yoonju Oh and co-authors review bandgap engineering in stacked two-dimensional materials through density functional theory. Layered materials can be stacked into structures with tuned traits. Their combined properties can beat any single layer alone.
The review covers stacks of graphene, boron nitride, and related sheets. Transition metal compounds and blue phosphorus also feature. Bandgap tuning serves transistors, light sensors, and solar cells. Theory predicts band structure before costly lab synthesis. The authors sort methods for engineering the gap by design. They also weigh current limits of the theory approach. Future prospects for devices close the survey. The piece guides materials teams planning new stacks for devices.
