Two‐dimensional layered transition metal dichalcogenides have emerged as promising materials for supercapacitors and hydrogen evolution reaction (HER) applications. Herein, the molybdenum sulfide (MoS2)@vanadium sulfide (VS2) and tungsten sulfide (WS2)@VS2 hybrid nano‐architectures prepared via a facile one‐step hydrothermal approach is reported. Hierarchical hybrids lead to rich exposed active edge...
Atom‐level understanding of the emerging properties of interfaces introduced by chemical treatments is key to the development of electronic devices. Herein, changes in the 4H‐SiC (0001)/ interfaces upon interfacial nitridation are analyzed in an array of realistic models that differ in composition and atomic arrangement using first‐principles calculations within the density functional theory...
The band alignment and the electronic states at the GaInP/AInP(001) interface are explored with (hybrid) density functional theory. Thereby, CuPt‐type ordered crystals are focused. For the most stable interface, valence and conduction band offsets of 0.04 and −0.58 eV, respectively, are predicted. No interface states occur within the fundamental gap. Generally, the results support the validity of...
