Influence of Cu purity and low temperature annealing on Cu/Zn disorder and efficiency of CZTSSe monograins Open
Thin film solar cell technologies are mainly based on polycrystalline absorber layers, which is also the case for kesterite-based photovoltaic devices. An alternative technology, which is promising and low cost, is based on kesterite-type …

Uncovering cation disorder in ternary Zn<sub>1+<i>x</i></sub>Ge<sub>1−<i>x</i></sub>(N<sub>1−<i>x</i></sub>O<sub><i>x</i></sub>)<sub>2</sub> and its effect on the optoelectronic properties Open
Ternary nitrides have potential as sustainable solar absorber materials. Their structures permit unique bandgap tuning through cation disorder. We experimentally show two independent disorder modes influencing the bandgap in similar but di…

Impact of Erbium Doping in the Structural and Magnetic Properties of the Anisotropic and Frustrated SrYb2O4 Antiferromagnet Open
We present a systematic study of the structural and magnetic properties of a series of powder samples of SrYb2−xErxO4 with different Yb/Er concentrations. Magnetometry and neutron diffraction have been used to study the magnetic ground sta…

On the Highly Ordered Graphene Structure of Non-Graphitic Carbons (NGCs)—A Wide-Angle Neutron Scattering (WANS) Study Open
Non-graphitic carbons (NGCs), such as glass-like carbons, pitch cokes, and activated carbon consist of small graphene layer building stacks arranged in a turbostratic order. Both structure features, including the single graphene sheets as …
The kesterite–stannite structural transition as a way to avoid Cu/Zn disorder in kesterites: the exemplary case of the Cu<sub>2</sub>(Zn,Mn)SnSe<sub>4</sub> Open
Cu/B II disorder is significantly reduced with Mn incorporation and the kesterite–stannite structural phase transition in Cu 2 (Zn,Mn)SnSe 4 .

A thorough investigation of the crystal structure of willemite‐type Zn<sub>2</sub>GeO<sub>4</sub> Open
The thermodynamically stable phase of Zn 2 GeO 4 contains tetrahedrally coordinated cations only and crystallizes isostructurally to Zn 2 SiO 4 (willemite, space group , no. 148). While this material is considered for a plethora of energy‐…

Unravelling the crystal structure of Nd<sub>5.8</sub>WO<sub>12−δ</sub> and Nd<sub>5.7</sub>W<sub>0.75</sub>Mo<sub>0.25</sub>O<sub>12−δ</sub> mixed ionic electronic conductors Open
Mixed ionic electronic conducting ceramics Nd 6− y WO 12−δ (δ is the oxygen deficiency) provide excellent stability in harsh environments containing strongly reactive gases such as CO 2 , CO, H 2 , H 2 O or H 2 S. Due to this chemical stab…

The influence of deuteration on the crystal structure of hybrid halide perovskites: a temperature-dependent neutron diffraction study of FAPbBr<sub>3</sub> Open
This paper discusses the full structural solution of the hybrid perovskite formamidinium lead tribromide (FAPbBr 3 ) and its temperature-dependent phase transitions in the range from 3 K to 300 K using neutron powder diffraction and synchr…
Crystal Structure and Thermal Behavior of SbC2O4OH and SbC2O4OD Open
The order of OH groups in the crystal structure of SbC2O4OH, a potential precursor in the synthesis of ternary oxides, was debated. Neutron diffraction on the deuteride SbC2O4OD revealed disordered OD groups with half occupation for deuter…
