Quantitative Analysis of Composition and Contamination of Atomically Thin Materials by Recoil-Projectile Coincidence in Ion Transmission
Carolin Frank, Kevin Vomschee, Tuan Thien Tran +6
Surface contamination strongly affects the intrinsic properties of nanoscale materials, making its reliable identification and quantification crucial for both accurate experimental…
Origin of circular and triangular pores in electron-irradiated hexagonal boron nitride
Umair Javed, Manuel Langle, Vladimir Zobac +9
For nearly two decades, it has been known that electron irradiation of hexagonal boron nitride (hBN) in a transmission electron microscope leads to the formation of triangular pore…
Electron-beam induced methane decomposition for in-situ carbon doping of hexagonal boron nitride
Barbara Maria Mayer, Manuel Längle, Umair Javed +3
Controlling the spatial incorporation of carbon into hexagonal boron nitride (hBN) is essential for engineering optically active defects, yet existing approaches lack nanoscale pre…
Single photon emitters in hBN: Limitations of atomic resolution imaging and potential sources of error
David Lamprecht, Shrirang Chokappa, Alissa M. Freilinger +9
There is a growing interest in identifying the origin of single-photon emission in hexagonal boron nitride (hBN), with proposed candidates including boron and nitrogen vacancies as…
Defect-engineering hexagonal boron nitride using low-energy Ar+ irradiation
Manuel Längle, Barbara Maria Mayer, Jacob Madsen +7
Monolayer hexagonal boron nitride (hBN) has recently become the focus of intense research as a material to host quantum emitters. Although it is well known that such emission is as…
