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…
Giant magnetic broadening of ferromagnetic resonance in a GMR Co/Ag/Co/Gd quadlayer
Sezen Demirtas, Ali R. Koymen, Myron B. Salamon
Both magnetic-resonance damping and the giant magnetoresistance effect have been predicted to be strongly affected by the local density of states in thin ferromagnetic films. We em…
