Publikováno v: Journal of Analytical Atomic Spectrometry. 36:56-63

The study demonstrates a new method to quantify Secondary Ion Mass Spectrometry (SIMS) data by using a synergetic combination of Energy Dispersive X-ray spectroscopy (EDX) and SIMS. The novelty of this approach lies in using a diffusion couple to pro

Helium implantation in epitaxial thin films is a way to control the out-of-plane deformation independently from the in-plane strain controlled by epitaxy. In particular, implantation by means of a helium microscope allows for local implantation and p

The physicochemical properties used in numerous advanced nanostructured devices are directly controlled by the oxidation states of their constituents. In this work we combine electron energy-loss spectroscopy, blind source separation, and computed to

Publikováno v: Solar Energy Materials and Solar Cells. 160:398-409

The overall efficiencies of screen printed monocrystalline Si solar cells are limited by electrical losses across the Si-metallization interface. The process of metallization affects the emitter and space charge region of the solar cell, particularly
