Function follows form: From semiconducting to metallic towards superconducting PbS nanowires by faceting the crystal
Mohammad Mehdi Ramin Moayed, Sascha Kull, Angelique Rieckmann +8
In the realm of colloidal nanostructures, with its immense capacity for shape and dimensionality control, the form is undoubtedly a driving factor for the tunability of optical and…
Gas-induced segregation in Pt-Rh alloy nanoparticles observed by in-situ Bragg coherent diffraction imaging
Tomoya Kawaguchi, Thomas F. Keller, Henning Runge +11
Bimetallic catalysts can undergo segregation or redistribution of the metals driven by oxidizing and reducing environments. Bragg coherent diffraction imaging (BCDI) was used to re…
A New Synthesis Approach for Carbon Nitrides: Poly (Triazine Imide) and Its Photocatalytic Properties
Leonard Heymann, Bjoern Schiller, Heshmat Noei +2
Poly (triazine imide) (PTI) is a material belonging to the group of carbon nitrides and has shown to have competitive properties compared to melon or g-C3N4, especially in photocat…
High Performance n- and p-Type Field-Effect Transistors Based on Hybridly Surface-Passivated Colloidal PbS Nanosheets
Mohammad Mehdi Ramin Moayed, Thomas Bielewicz, Heshmat Noei +2
Colloidally synthesized nanomaterials are among the promising candidates for future electronic devices due to their simplicity and the inexpensiveness of their production. Specific…
Kinetic hindrance during the initial oxidation of Pd(100) at ambient pressures
E. Lundgren, A. Stierle, M. Todorova +7
The oxidation of the Pd(100) surface at oxygen pressures in the 10^-6 to 10^3 mbar range and temperatures up to 1000 K has been studied in-situ by surface x-ray diffraction (SXRD).…
