چکیده
Considering the recent developments of the pulsed laser in the femtosecond domain, the possibility of conceiving a new laser assisted Tomographic Atom Probe has been nvisaged. The instrument is able to map out the 3D distributions of the atomic positions in a The interest of the terial sciences has already been demonstrated many times [3,4]. However, since HV mples have to be electrically good conducting material. Thus, the 3DAP is really hy Applications B Gault, E Mottay, A Courjaud, 1 Groupe de Physique des Matériaux UMR CNRS 6634, Université de Rouen B.P. 12 76801 SAINT ETIENNE DU ROUVRAY CEDEXFrance 2 AMPLITUDE SYSTEMES Domaine du Haut Carré 351, Cours de la Libération 33400 Talence – France E-Mail : [email protected] e volume about 20 20 200 nm. By combining a standard atom probe to a femtosecond laser, it is possible to obtain excellent atom probe performances. The mass resolving power of the instrument is increased by a factor 3. The feasibility of a laser assisted Tomographic Atom Probe is thus demonstrated in conductive and non conductive materials.

Gap tips prepared f ran whiskers grown by the vapour phase reaction, were analyzed using our ctmbined-type atom-probe FIM by laser pulse operation instead of high voltage pulse operation. It was found that ( 1 ) The mposition is Ga : P=l : l at cryogenic temperature 45K in vacuum of better than 1 x 10-Ptorr. ( 2 ) Much more cluster ions of phosphorus atan in laser pulse mode are detected in can...
متن کاملEffects of laser energy and wavelength on the analysis of LiFePO₄ using laser assisted atom probe tomography.
The effects of laser wavelength (355 nm and 532 nm) and laser pulse energy on the quantitative analysis of LiFePO₄ by atom probe tomography are considered. A systematic investigation of ultraviolet (UV, 355 nm) and green (532 nm) laser assisted field evaporation has revealed distinctly different behaviors. With the use of a UV laser, the major issue was identified as the preferential loss of ox...
متن کاملUltrafast laser-triggered field ion emission from semiconductor tips
We study experimentally and theoretically the controlled field evaporation of single atoms from a semiconductor surface by ultrafast laserassisted atom probe tomography. The conventional physical mechanisms of field evaporation cannot explain the experimental results recently reported for such materials. A new model is presented in which the positive dc field leads to band bending with a high d...
متن کاملPulsed-laser atom probe studies of a precipitation hardened maraging TRIP steel.
A precipitation hardened maraging TRIP steel was analyzed using a pulsed laser atom probe. The laser pulse energy was varied from 0.3 to 1.9 nJ to study its effect on the measured chemical compositions and spatial resolution. Compositional analyses using proximity histograms did not show any significant variations in the average matrix and precipitate compositions. The only remarkable change in...
