Article Synopsis
- * Researchers used plasma-enhanced ALD to grow large-area MoS and examined how high-κ dielectrics like HfO and AlO impact the electrical properties and doping of these transistors.
- * Findings indicate that factors such as dielectric stoichiometry, carbon impurities, and surface oxidation significantly influence MoS FET performance, with the optimal setup involving thermal ALD AlO to minimize surface damage while enhancing dielectric characteristics.
Article Synopsis
- Mn-Rh nanoparticles show promise as catalysts for producing syngas, an important industrial precursor.
- This study uses theoretical and computational methods to examine how these nanoparticles interact with titanium oxide (TiO2) surfaces and their catalytic efficiency.
- Findings reveal insights into the stability, reactivity, and role of Mn and Rh in enhancing syngas generation through specific reactions, indicating their potential for sustainable industrial applications.
Article Synopsis
- * Thin films of amorphous MoS demonstrate significant activity improvements after electrochemical activation, with an optimal overpotential range of 210-250 mV, influenced by their initial stoichiometry.
- * The study reveals that while amorphous MoS undergoes structural changes during activation, crystalline MoS remains stable, with lower hydrogen evolution efficiencies observed in crystalline forms (300-520 mV at 10 mA/cm) correlating with defects in the material.
We utilize plasma-enhanced atomic layer deposition to synthesize two-dimensional Nb-doped WS and NbWS alloys to expand the range of properties and improve the performance of 2D transition metal dichalcogenides for electronics and catalysis. Using a supercycle deposition process, films are prepared with compositions spanning the range from WS to NbS. While the W-rich films form crystalline disulfides, the Nb-rich films form amorphous trisulfides.
