Nettet18. jun. 2015 · Due to its monolayer sensitivity, straight-forward quantification and good detection limits, low energy ion scattering (LEIS) is routinely used in the characterization of ultra-thin films to address analytical questions like layer closure, surface composition, diffusion processes, or growth modes. Nettet5. okt. 2024 · Monte-Carlo-based simulations were used to predict LEIS spectra, which allowed for quantitative analysis of nucleation and film growth. These simulated spectra of few-layer films further confirmed that the grown films exhibited uniform nucleation. ACKNOWLEDGMENTS.

Nettet28. feb. 2009 · In many cases, the HS-LEIS spectra are recorded with different primary ions since the HS-LEIS analyst is free to choose the primary ion. The spectra with 4 … Nettet20. sep. 2004 · LEIS showed a strong decrease of Ni intensity and a pronounced relative increase of O intensity. It can be well explained by the formation of a carbon bonded CO and O overlayer. TPD spectrum in Fig. 5 shows the main peak at 510 K. This value is anomalously high comparing to 440 K for ordered Ni 3 Al (1 1 1) [3] and for Ni (1 0 0) … men\u0027s scout chukka boot
Influence of screening and electronic stopping on LEIS spectra
Nettet17. mar. 2024 · LEIS spectra contain depth-resolved information in the so-called sub-surface signal. However, the exact correlation between the sub-surface signal and the … NettetIn this work, we present a novel non-rigid shape matching framework based on multi-resolution functional maps with spectral attention. Existing functional map learning methods all rely on the critical choice of the spectral resolution hyperparameter, which can severely affect the overall accuracy or lead to overfitting, if not chosen carefully. NettetThe surface selectivity of the peaks in LEIS spectra enables the characterization of the change in surface coverage as a function of the as-deposited film thickness, … men\u0027s scratch race crash
