2D Materials

Morphological evolution during epitaxial 2D islands and sheets growth has been an interesting research topic for a long time. In recent years, the rapid development of 2D materials, i.e., graphene, transition metal dichalcogenides and oxides, have gained tremendous attention in the fields of materials science, nano-electronics, photonics, and energy technology. One of the interesting properties of 2D materials is the large surface edges, which provides plethora of opportunities for realizing novel physical phenomenon via controlling edge defects and grain boundaries. Not to mention the unpredictable opportunities after combining the 2D crystals in one vertical stack. Therefore, it is important to know how to control 2D materials growth by modifying the reaction conditions. Our high performance code is a good platform to accelerate 2D material applications by controllable growth morphology and grain boundaries.
