A Fully-Reduced, Highly-Disordered Nitride-Halide Electrolyte for Solid-State Batteries with Lithium-Metal Anodes
Most highly Li-conducting solid electrolytes (σRT > 10-3 S cm-1) are unstable against lithium-metal and suffer from detrimental solid-electrolyte decomposition at the lithium-metal/solid-electrolyte interface. Solid electrolytes that are stable against lithium metal thus offer a

Optical hydrogen sensing beyond palladium
Hafnium and tantalum as effective sensing materials
The detection of hydrogen in a fast, efficient and accurate way is vital for its safe handling in industrial processes and in its use as an energy carrier. Thin film metal hydrides are able to probe the hydrogen pressure, often relying on a change of the optical properties of a s

Understanding and mitigating resistive losses in fired passivating contacts
Role of the interfaces and optimization of the thermal budget
This work presents a study of p-type passivating contacts based on SiCx formed via a rapid thermal processing (RTP) step, using conditions compatible with the firing used to sinter screen-printed metallization pastes in industry. The contributions of the two interfaces (wafer/con

Aliovalent Calcium Doping of Yttrium Oxyhydride Thin Films and Implications for Photochromism (The Journal of Physical Chemistry C (2022) 126:34 (14742−14749) DOI:10.1021/acs.jpcc.2c04456)
The energy axes of the RBS and ERD data (contained in Figures 2a,b,d,e, and S4) were originally underestimated, and the corrected figures appear below and in the Supporting Information. The change is in the conversion from raw data to the energy scale, which was initially convert

Magnetic relaxation phenomena in the chiral magnet Fe1−xCoxSi
An ac susceptibility study
We present a systematic study of the ac susceptibility of the chiral magnet Fe1−xCoxSi with x=0.30 covering four orders of magnitude in frequencies from 0.1 Hz to 1 kHz, with particular emphasis to the pronounced history dependence. Characteristic relaxation times ranging from a

Evolution of helimagnetic correlations in Mn1-xFexSi with doping
A small-angle neutron scattering study
We present a comprehensive small-angle neutron scattering study of the doping dependence of the helimagnetic correlations in Mn1−xFexSi. The long-range helimagnetic order in Mn1−xFexSi is suppressed with increasing Fe content and disappears for x>x∗≈0.11, i.e., well before xC≈0.1
