The first energy-resolved photoemission experiments which used synchrotron radiation were performed on the Tantalus Storage Ring at the University of Wisconsin. The Ring was the first dedicated light source and during the winter of 1970–1971 D.E. E

We have measured the photon energy dependence of the O 1s2p2p Auger line at the O K threshold, below Mn L 2,3 as well as well above the Mn L 2,3 -edge of colossal magnetoresistance (CMR) manganites Pr 1− x Sr x MnO 3 (PSMO) with x =0.0 and x =0.3 c

The k derivative spectra (KDS) transform is used for construction of the three-dimensional atomic structure of the C 2 H 4/ Si (100)-(2×1) system from photoelectron diffraction data. The image function obtained by the KDS transform clearly observes

We have used low energy electron-excited nanoluminescence (LEEN) spectroscopy to probe the localized electronic states at GaN free surfaces, metal–GaN contacts, and GaN/InGaN quantum well interfaces. These depth-resolved measurements reveal the pre

A new adsorption site for adsorbed acetylene on Si(100) is observed by photoelectron imaging based on the holographic principle. The diffraction effects in the carbon $1s$ angle-resolved photoemission are inverted (including the small-cone method) to

We have used low-energy electron-excited nanoscale-luminescence (LEEN) spectroscopy combined with ultrahigh vacuum (UHV) surface science techniques to probe deep level defect states at GaN free surfaces, metal-GaN contacts and GaN/InGaN quantum well

The adsorption and reaction of acetylene with the $\mathrm{Si}(100)\ensuremath{-}2\ifmmode\times\else\texttimes\fi{}1$ surface has been studied using high-resolution photoemission by monitoring the $\mathrm{Si}2p, \mathrm{C}1s,$ and valence-band (VB)

Depth-dependent low energy cathodoluminescence spectroscopy (CLS) has been used to investigate the near-surface optical properties of n-type GaN epelayers grown under various growth conditions. Both bare and reacted-Mg/n-GaN and Al/n-GaN (annealed to

High-resolution electron energy-loss spectroscopy (HREELS) has been used in situ to investigate the space charge regime of homogeneously doped and delta-doped (Si) GaAs (100) samples, which were grown by molecular beam epitaxy (MBE). The simplest mod
