Evidence Of A Positron Bound State On The Surface Of A Topological Insulator
Shastry, Karthik (Physics, 2014-12)We describe experiments aimed at probing the sticking of positrons to the surfaces of topological insulators performed at university of Texas at Arlington using the Positron Annihilation induced Auger electron Spectrometer. ... -
First Measurements Of The Low Energy Tail (LET) Down To 0 eV Using Auger Photoelectron Coincidence Spectroscopy (APECS) In Ag (100) And Cu (100)
Shastry, Karthik (Physics, 2011-03-03)We present the Auger Photoelectron Coincidence Spectroscopy (APECS) measurements of Ag (100) and Cu (100) over a full range of emitted energies from 0 eV to 81eV. The coincidence measurements were successful in separating ...
