Identification of Auger mechanisms responsible for low energy electron emission from graphene on copper using Auger-gamma coincidence spectroscopy
R. W. Gladen, V. A. Chirayath, P. A. Sterne +3
We present a novel method for the analysis of the Doppler broadened spectrum of gamma photons emitted following the annihilation of surface trapped positrons with the electrons of…
Direct evidence for low-energy electron emission following O LVV Auger transitions at oxide surfaces
Alexander J. Fairchild, Varghese A. Chirayath, Philip A. Sterne +3
Oxygen, the third most abundant element in the universe, plays a key role in the chemistry of condensed matter and biological systems. Here, we report evidence for a hitherto unexp…
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…
