Intrinsic linewidths of confined phonons in few-layer hBN
Aleksandar Radic, Jack Kelsall, Akshay Rao
Understanding lattice vibrations in two-dimensional (2D) materials is essential for controlling thermal transport, mechanical response, and energy dissipation in nanoscale devices.…
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…
Minimising Interference in Low-Pressure Supersonic Beam Sources
Jack Kelsall, Aleksandar Radic, John Ellis +2
Free-jet atomic, cluster and molecular sources are typically used to produce beams of low-energy, neutral particles and find application in a wide array of technologies, from neutr…
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…
Implementing photometric stereo for scanning helium microscopy (SHeM) to reconstruct true-to-size 3D surfaces
Aleksandar Radic
Scanning Helium Microscopy (SHeM) offers a combination of spatial and angular resolution via a pinhole-collimated beam of thermal energy, neutral helium-4 atoms for non-destructive…
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…
