Stacked Semiconductor (IMAGE) DOE/Oak Ridge National Laboratory Caption Mutual rotation of two monolayers of a semiconducting material creates a variety of bilayer stacking patterns, depending on the twist angle. Fast and efficient characterization of these stacking patterns may aid exploration of potential applications in electronics and optoelectronics.
