Atomically clean free-standing two-dimensional materials through heating in ultra-high vacuum

Philipp Irschik, David Lamprecht, Shrirang Chokappa +6

Surface contamination not only influences but in some cases even dominates the measured properties of two-dimensional materials. Although different cleaning methods are often used…

Engineering two-dimensional materials from single-layer NbS $_{2}$

Timo Knispel, Daniela Mohrenstecher, Carsten Speckmann +10

Starting from a single layer of NbS $_{2}$ grown on graphene by molecular beam epitaxy, the single unit cell thick 2D materials Nb $_{5/3}$ S $_{3}$ -2D and Nb $_{2}$ S $_{3}$ -2D are created using…
