A fundamental understanding of the forces guiding surface motion is thus of utmost importance for the advancement of many fields of science and technology. To date, our understanding of the principles underlying surface dynamics remains extremely limited, due to the difficulties involved in measuring these processes experimentally. The helium-3 spin-echo (HeSE) technique is uniquely capable of probing such surface dynamical phenomena. The present thesis extends the field of application of HeSE from atomic and small molecular systems to more complex systems. Improvements to the supersonic helium beam source, a key component of the spectrometer, as well as a detailed investigation of a range of five-membered aromatic adsorbate species are presented. The thesis provides a comprehensive description of many aspects of the HeSE method - instrumentation, measurement and data analysis - and as such offers a valuable introduction for newcomers to the field. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aSurfaces (Physics) 606 $aInterfaces (Physical sciences) 606 $aThin films 606 $aChemistry, Physical and theoretical 606 $aAtoms 606 $aPhysics 606 $aPhysical measurements 606 $aMeasurement 606 $aMaterials?Surfaces 606 $aSurface and Interface Science, Thin Films$3https://scigraph.springernature.com/ontologies/product-market-codes/P25160 606 $aPhysical Chemistry$3https://scigraph.springernature.com/ontologies/product-market-codes/C21001 606 $aAtomic, Molecular, Optical and Plasma Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P24009 606 $aMeasurement Science and Instrumentation$3https://scigraph.springernature.com/ontologies/product-market-codes/P31040 606 $aSurfaces and Interfaces, Thin Films$3https://scigraph.springernature.com/ontologies/product-market-codes/Z19000 615 0$aSurfaces (Physics) 615 0$aInterfaces (Physical sciences) 615 0$aThin films. 615 0$aChemistry, Physical and theoretical. 615 0$aAtoms. 615 0$aPhysics. 615 0$aPhysical measurements. 615 0$aMeasurement. 615 0$aMaterials?Surfaces. 615 14$aSurface and Interface Science, Thin Films. 615 24$aPhysical Chemistry. 615 24$aAtomic, Molecular, Optical and Plasma Physics. 615 24$aMeasurement Science and Instrumentation. 615 24$aSurfaces and Interfaces, Thin Films. 676 $a530.417 700 $aLechner$b Barbara A.
