High resolution large working distance scanning helium microscopy
Sam M Lambrick, Nick A von Jeinsen, Alek Radić +4
Scanning helium microscopy (SHeM) is attractive for imaging delicate and insulating surfaces because it combines a non-destructive neutral-atom probe with strong surface sensitivit…
Characterising Atomic-Scale Surface Disorder on 2D Materials Using Neutral Atoms
Chenyang Zhao, Sam M. Lambrick, Ke Wang +5
Two-dimensional (2D) transition metal dichalcogenides (TMDs), such as MoS2, have the potential to be widely used in electronic devices and sensors due to their high carrier mobilit…
Defect-modified acoustic phonons in a single layer of MoS2
Aleksandar Radic, Boyao Liu, Akshay Rao +1
The thermal, mechanical, and electronic performance of atomically thin semiconductors is governed by their low-energy phonons, yet the impact of atomic-scale disorder on these mode…
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,…
A multi-detector neutral helium atom microscope
Chenyang Zhao, Sam M Lambrick, Nick A von Jeinsen +6
Scanning helium microscopy (SHeM) is an emerging technique that uses a beam of neutral atoms to image and analyse surfaces. The low energies (64 meV) and completely non-destr…
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…
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…
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…
3D surface profilometry using neutral helium atoms
Aleksandar Radic, Sam M. Lambrick, Nick A. von Jeinsen +2
Three-dimensional mapping of surface structures is important in a wide range of biological, technological, healthcare and research applications, including taxonomy, microfluidics a…
