The Microstructure of Tool Steel after Low Temperature Ion Nitriding
L. F. Zagonel, E. J. Mittemeijer, F. Alvarez
The microstructural development in H13 tool steel upon nitriding by an ion beam process was investigated. The nitriding experiments were performed at a relatively low temperature o…
Full field chemical imaging of buried native sub-oxide layers on doped silicon patterns
F. de la Peña, N. Barrett, L. F. Zagonel +2
Fully energy-filtered X-ray photoelectron emission microscopy is used to analyze the spatial distribution of the silicon sub-oxide structure at the SiO2/Si interface as a function…
Orientation-dependent surface composition of in situ annealed strontium titanate
Luiz F. Zagonel, Nicholas Barrett, Olivier Renault +5
The surface composition of polycrystalline niobium-doped strontium titanate (SrTiO3 : Nb) is studied using X-ray photoelectron emission microscopy (XPEEM) for many grain orientatio…
Orientation dependent work function of in situ annealed strontium titanate
L F Zagonel, M Bäurer, A Bailly +5
We have used energy filtered x-ray photoelectron emission microscopy (XPEEM) and synchrotron radiation to measure the grain orientation dependence of the work function of a sintere…
Nanometer Scale Spectral Imaging of Quantum Emitters in Nanowires and Its Correlation to Their Atomically Resolved Structure
Luiz Fernando Zagonel, Stefano Mazzucco, Marcel Tencé +9
We report the spectral imaging in the UV to visible range with nanometer scale resolution of closely packed GaN/AlN quantum disks in individual nanowires using an improved custom-m…
Visualising highly localised luminescence in GaN/AlN heterostructures in nanowires
L. F. Zagonel, L. Rigutti, M. Tchernycheva +3
The optical properties of a stack of GaN/AlN quantum discs (QDiscs) in a GaN nanowire have been studied by spatially resolved cathodoluminescence (CL) at the nanoscale (nanoCL) usi…
