In recent years, twisted bilayer systems in atomic layer materials have been focused on due to their ability to exhibit diverse physical properties that single-layer materials cannot achieve. We discovered a one-dimensional moiré structure in twisted bilayer borophane using transmission electron microscopy (TEM). Through structural model analysis, we determined that twisted bilayer borophane can form one-dimensional moiré structures, two-dimensional moiré structures, and approximate-crystalline structures, all depending on the twist angle. This study also investigated the origins of these structures and the electronic properties they generate.
