Journal ArticleDOI
Electron-hole pair excitation determines the mechanism of hydrogen atom adsorption.
Oliver Bünermann,Oliver Bünermann,Hongyan Jiang,Yvonne Dorenkamp,Alexander Kandratsenka,Svenja M. Janke,Svenja M. Janke,Daniel J. Auerbach,Daniel J. Auerbach,Alec M. Wodtke,Alec M. Wodtke +10 more
TL;DR: It is shown through experiments that H-atom collisions at an insulating surface (an adsorbed xenon layer on a gold single-crystal surface) are indeed nearly elastic, following the predictions of energy and momentum conservation.
Journal ArticleDOI
Imaging covalent bond formation by H atom scattering from graphene.
Hongyan Jiang,Hongyan Jiang,Marvin Kammler,Marvin Kammler,Feizhi Ding,Yvonne Dorenkamp,Yvonne Dorenkamp,Frederick R. Manby,Alec M. Wodtke,Alec M. Wodtke,Thomas F. Miller,Alexander Kandratsenka,Oliver Bünermann +12 more
TL;DR: This work performs scattering experiments of H atoms from graphene and observed a bimodal translational energy loss distribution and shows that the quasi-elastic channel involves scattering through the physisorption well where collision sites are near the centers of the six-membered C-rings.
Journal ArticleDOI
Unified description of H-atom-induced chemicurrents and inelastic scattering.
Alexander Kandratsenka,Alexander Kandratsenka,Hongyan Jiang,Yvonne Dorenkamp,Svenja M. Janke,Svenja M. Janke,Marvin Kammler,Marvin Kammler,Alec M. Wodtke,Alec M. Wodtke,Oliver Bünermann,Oliver Bünermann +11 more
TL;DR: The theory explains the magnitude of chemicurrents on Ag Schottky diodes and resolves an apparent paradox––chemicurrents exhibit a much larger isotope effect than does H/D inelastic scattering.
Journal ArticleDOI
Hydrogen collisions with transition metal surfaces: Universal electronically nonadiabatic adsorption.
Yvonne Dorenkamp,Hongyan Jiang,Hansjochen Köckert,Nils Hertl,Marvin Kammler,Svenja M. Janke,Alexander Kandratsenka,Alec M. Wodtke,Oliver Bünermann +8 more
TL;DR: Inelastic scattering of H and D atoms from the surfaces of six fcc transition metals was investigated, and in each case, excitation of electron-hole pairs dominates the inelasticity.
Journal ArticleDOI
An ultrahigh vacuum apparatus for H atom scattering from surfaces
TL;DR: An apparatus to study inelastic H or D atom scattering from surfaces under ultra-high vacuum conditions by combining a photolysis-based atom source with Rydberg atom tagging time-of-flight and provides high resolution information on scattering energy and angular distributions.
