Photoemission spectroscopy using virtual photons emitted by positron sticking: a new probe of the top layer surface electronic structure
Alexander J Fairchild, Varghese A. Chirayath, Bernardo Barbiellini +3
We present a spectroscopic method which utilizes virtual photons to selectively measure the electronic structure of the top-most atomic layer. These virtual photons are created whe…

Application of Doppler Broadened Gamma Spectroscopy to Study the Surface of Graphene
A. H. Weiss, V. A. Chirayath, R. W. Gladen +4
We present Doppler broadened gamma spectra, obtained using the newly developed advanced positron beam at the University of Texas at Arlington, from a sample consisting of 6 to 8 la…
