  1. Helium Atom Scattering from Chiral Structures

    Eratam, FuldenUniversity of Cambridge2022

    Helium Atom Scattering (HAS) is the only diffraction technique that combines absolute sur- face sensitivity with non-destructiveness and universality, but has been seldom applied to the study of chiral surfaces. The current thesis focuses on advancing the available theoretical and experimental tools …

  5. Studying complex surface dynamical systems using helium-3 spin-echo spectroscopy

    Lechner, Barbara Angelika JohannaUniversity of Cambridge2012

    … is to extend the range of application of the helium-3 spin-echo (HeSE) technique to complex surface dynamical systems. A twofold approach is presented: the development of improved experimental equipment and the investigation of a series of prototypical aromatic adsorbate systems. Chapter 1 …

  6. Ultrafast Dynamics and Interactions During Growth at Surfaces

    Kelsall, JohnUniversity of Cambridge2023

    Helium-3 spin-echo (3HeSE) is a helium atom scattering technique capable of studying nanoscopic surface dynamics in thermal equilibrium. The energy resolution, which greatly exceeds that of alternative methods, makes it possible to probe motion on picosecond to nanosecond timescales. The present …

  7. The formation of contrast in scanning helium microscopy

    Lambrick, SamUniversity of Cambridge2021

    The formation of contrast in scanning helium microscopy Over the last decade a new microscopy technique has emerged that uses neutral helium atoms as the probe particles. It has been termed scanning helium microscopy (SHeM), also known as neutral atom microscopy (NAM). SHeM produces helium atom …
