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…
On the nature of tunable hole g-factors in quantum dots
N. Ares, V. N. Golovach, G. Katsaros +5
Electrically tunable g-factors in quantum dots are highly desirable for applications in quantum computing and spintronics. We report giant modulation of the hole g-factor in a SiGe…
Statistical inference in compound functional models
Arnak Dalalyan, Yuri Ingster, Alexandre Tsybakov
We consider a general nonparametric regression model called the compound model. It includes, as special cases, sparse additive regression and nonparametric (or linear) regression w…
Detection of a large valley-orbit splitting in silicon with two-donor spectroscopy
Benoit Roche, Eva Dupont-Ferrier, Benoit Voisin +6
We measure a large valley-orbit splitting for shallow isolated phosphorus donors in a silicon gated nanowire. This splitting is close to the bulk value and well above previous repo…
