Electron Emission From Surfaces Resulting From Low Energy Positron Bombardment
Mukherjee, Saurabh (Physics, 2009-09-16)Measurements of the secondary electron energy spectra resulting from very low energy positron bombardment of a polycrystalline Au and Cu (100) surfaces are presented that provide evidence for a single step transition from ... -
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. ... -
Experimental Studies Of Fundamental Aspects Of Auger Emission Process In Cu(100) And Ag(100)
Joglekar, Prasad Vivek (Physics, 2014-09-17)Auger spectra at the low energies are accompanied by large contributions unrelated to the Auger transition. The Auger unrelated contributions can obscure the Auger peak and affect the quantitative analysis of the materials ... -
First Direct Measurement Of The Energy Spectra Of Individual Auger Cascade Steps In Solid MnO, Ag And Pd
Sundaramoorthy, Rajalakshmi (Physics, 2007-09-17)We present the first direct measurements of energy spectra of electrons emitted in the later steps of the Auger cascade processes in solids. Measurements were carried out for the L-->MV-->VVV and L-->MM-->MVV-->VVVV Auger ... -
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 ... -
Measurement Of The Spectral Distribution Of The Low Energy Electrons Emitted As A Result Of M₃VV Auger Transitions In Cu(100)
Satyal, Suman (Physics, 2012-04-11)Auger Photoelectron Coincidence Spectroscopy (APECS) was used to investigate the physics of the Low Energy Tail (LET) region of the Auger spectrum of a Cu(100) sample. Two Cylindrical Mirror Analyzers (CMAs) were used to ... -
Study Of Oxide Surfaces Using Time Of Flight Positron Annihilation Induced Auger Electron Spectroscopy
Nadesalingam, Manori Prasadika (Physics, 2007-08-23)Transition metal oxides (TMOs) exhibit a rich collection of interesting and intriguing properties which can be used for wide variety of applications. In this dissertation, I will discuss the first PAES measurements on ... -
THE SEARCH FOR EXOMOON RADIO EMISSIONS
Noyola, Joaquin P; 0000-0002-7468-9037 (2015-12-07)The field of exoplanet detection has seen many new developments since the discovery of the first exoplanet. Observational surveys by the NASA Kepler Mission and several other instrument have led to the confirmation of over ...
