Competition between vacancy creation and filling in defect-engineering of hBN
Shrirang Chokappa, Manuel Längle, Barbara Maria Mayer +13
Hexagonal boron nitride (hBN) has recently become the focus of intense research as a material that can host quantum emitters. It is known that such emission is related to point def…

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…
