It is well established that clusters of both vacancies and self-interstitial atoms (SIAs) are produced in displacement cascades. Ample evidence has also been presented showing that SIAs produced in the form of small dislocation loops may be highly glissile ...
Molecular dynamics simulations of the impact of Ag atoms at low energies (20 eV and 95 eV in the direction perpendicular to the surface) on Pd(100) are performed using embedded atom (EAM) potentials. The results are compared with recent helium scattering d ...
Photoluminescence (PL), reflectivity and thermally-detected optical absorption (TDOA) experiments have been carried out, at liquid helium temperatures, On In0.35Ga0.65As/GaAs quantum wells (QWs) with different thicknesses of 4, 6, 8 and 10 monolayers (MLs) ...
A study on the effect of growth interruptions on InAs/InP strained quantum wells (QW) by cathodoluminescence (CL) at helium temperature and transmission electron microscopy (TEM) is reported. The samples are grown by chemical beam epitaxy (CBE) with and wi ...
Thermally detected optical absorption measurements have been performed at liquid helium temperature in order to study the effects of In segregation on the optical properties of InxGa1-xAs/GaAs quantum wells grown by molecular-beam epitaxy under various gro ...
In a recent paper we measured the lateral hole diffusion in a GaAs/AlGaAs single quantum well (SQW) by a novel method. At helium temperature, we estimate a lateral hole diffusion length in the QW of 1.5 mum. However, the assumption that diffusion takes pla ...
To study the effect of damage induced during the Zn diffusion on the properties of the material, p-n junctions, obtained by zinc diffusion, are investigated by electron beam induced current (EBIC) at different temperatures. At helium temperature, the EBIC ...
We report a cathodoluminescence (CL) study at helium temperature of oval defects on quantum well (QW) structures grown by molecular beam epitaxy (MBE). We collected the luminescence emitted both from the facet shaped defect and from the defect free growth ...
A spectrometer has been constructed for the study of (n, α) reactions at 14 MeV, By detecting the 4He particle associated with neutron production, it is possible to measure the a time-of-flight in addition to the residual energy and energy loss, as measure ...
