We have developed an original time resolved cathodoluminescence (TRCL) set-up with temporal performances similar to those of conventional time resolved optical techniques, keeping the capability to get structural information through the secondary electron ...
In this paper we present our latest developments in high precision positioning and handling systems operating inside an SEM. The Laboratory in Scanning Electron Microscope concept (LAB-in-SEM) is proposed along with a description of our piezodriven manipul ...
The focused electron beam induced deposition process is a promising technique for nano and micro patterning. Electrons can be focused in sub-angström dimensions, which allows atomic-scale resolution imaging, analysis, and processing techniques. Before the ...
We report on a novel approach to measure the phase relaxation length and femtosecond lifetime of hot quasiparticles on metal surfaces. A 4 K scanning tunneling microscope has been used to study the spatial decay of interference patterns in the local densit ...
The knowledge of the inelastic double differential scattering cross section (DDSCS) is of utmost importance for microanalysis in electron energy loss spectrometry (EELS) in the electron microscope and for the investigation of electron energy loss near edge ...
We explored degradation in electron-beam-pumped Zn1-xCdxSe/ZnSe laser structures by combining cathodoluminescence (CL) measurements in a scanning electron microscope with transmission electron microscopy. The rate of degradation, measured as the decrease o ...
A method for preparing and observing clay platelets for size and shape analysis using scanning electron microscopy (SEM) was developed. Samples of the clay platelets were prepared by polyelectrolyte-assisted adsorption onto a pyrolytic graphite surface. Th ...
Information for phase identification may be gathered in the electron transmission microscope with spatial resolution down to the nanometre scale. Energy dispersive X-ray and electron energy loss spectrometries are based on inelastic electron/sample interac ...
Codeposition of hydrocarbons is a severe problem during focused electron beam writing of pure metal nanostructures. When using organometallic precursors, a low metal content carbonaceous matrix embedding and separating numerous nanosized metal clusters is ...
Designing microstructure for damage tolerance requires a detailed understanding of how an advancing crack interacts with the microstructure (and sometimes modifies it locally) at multiple length scales. Advances in experimental techniques, such as the avai ...
