Positron Induced Electron Emission from Graphite
A. J. Fairchild, V. A. Chirayath, R. W. Gladen +2
In this paper, we present and analyze measurements of the positron induced electron spectra (PIES) from highly oriented pyrolytic graphite (HOPG). The spectra were obtained using a…
Direct observation of electron emission as a result of a VVV Auger transition in the valence band of Graphene
V. A. Chirayath, V. Callewaert, M. D. Chrysler +11
We report the first direct observation of electron emission into the vacuum as a result of a VVV Auger transition resulting from the relaxation of a deep hole in the valence band.…
Positron surface state as a spectroscopic probe for characterizing surfaces of topological insulator materials
Vincent Callewaert, K. Shastry, Rolando Saniz +8
Topological insulators are attracting considerable interest due to their potential for technological applications and as platforms for exploring wide-ranging fundamental science qu…
Measurement of the background in Auger-photoemission coincidence spectra (APECS) associated with inelastic or multi-electron valence band photoemission processes
S. Satyal, P. V. Joglekar, K. Shastry +5
Auger Photoelectron Coincidence Spectroscopy (APECS), in which the Auger spectra is measured in coincidence with the core level photoelectron, is capable of pulling difficult to ob…
Background Free Measurement of the Spectra of Low Energy Electrons Emitted as a Result of Auger Transitions in Metals
S. F. Mukherjee, K. Shastry, A. H. Weiss
Positron annihilation induced Auger electron spectroscopy was used to obtain Cu and Au Auger spectra that are free of primary beam induced background by impinging the positrons at…
