Measuring vacancy-type defect density in monolayer semiconductors
Aleksandar Radic, Nick von Jeinsen, Vivian Perez +12
Two-dimensional (2D) materials have attracted wide-spread interest due to their unique and tunable properties. Their optoelectronic, mechanical, and thermal properties are greatly…
Heliometric stereo: a new frontier in surface profilometry
Aleksandar Radic, Sam Lambrick, Chenyang Zhao +4
Accurate and reliable measurements of three-dimensional surface structures are important for a broad range of technological and research applications, including materials science,…
On the application of components manufactured with stereolithographic 3D printing in high vacuum systems
Aleksandar Radic, Sam Lambrick, Sam Rhodes +1
We explore the ultrahigh-vacuum (UHV) compatibility of Formlabs `Clear Resin' via vat photopolymerization (VPP). We report on a method for using VPP additive manufacturing, specifi…
Helium atom micro-diffraction as a characterisation tool for 2D materials
Nick von Jeinsen, Aleksandar Radic, Ke Wang +7
We present helium atom micro-diffraction as an ideal technique for characterization of 2D materials due to its ultimate surface sensitivity combined with sub-micron spatial resolut…
