Two-dimensional (2D) material element with in-plane metal chalcogenide-based heterojunctions and devices including said element

摘要

According to example embodiments, a two-dimensional (2D) material element may include a first 2D material and a second 2D material chemically bonded to each other. The first 2D material may include a first metal chalcogenide-based material. The second 2D material may include a second metal chalcogenide-based material. The second 2D material may be bonded to a side of the first 2D material. The 2D material element may have a PN junction structure. The 2D material element may include a plurality of 2D materials with different band gaps.
