Enhanced Thermoelectric Performance of GeTe‐Sb2Te3 Pseudo‐Binary Phase Change Material Through Stoichiometry Optimization

Advanced Electronic Materials, EarlyView.
A GeTe‐Sb2Te3 composition spread is fabricated using RF magnetron co‐sputtering. Increasing Sb content stabilized the high‐performance cubic GeTe phase. The composition 5Sb3₇Te5₈ exhibited the highest thermoelectric performance, achieving a power factor of ∼1 mW m−1 K−2 and a maximum zT of 0.81 at 300°C.

Dimensional Reduction of Transition Metal Dichalcogenides by Oxide Insertion: Quasi‐1D Oxychalcogenide Semiconductors

Angewandte Chemie, EarlyView.
Molecular Scissors: Oxide insertion slices the layers of MQ2 transition metal dichalcogenides (TMDs) into one‐dimensional [M3Q6] nanoribbons, giving a new family of A2Hf3Q6O (A = K, Rb, Cs; Q = S, Se) oxychalcogenides. The heteroanion‐driven dimensional reduction yields direct‐gap semiconductors with optical absorption that is tunable across the ...

Borosulfates Hosting Se42+ Ions—Crystal Structures, Chemical Bonding, Optical Spectroscopy, and Magnetism

Angewandte Chemie, EarlyView.
Apart from (transition) metal (oxo)halides only few hosts stabilize chalcogenide cations in purely oxoanionic coordination environment. Herein, we report on five borosulfates containing the Se42+ ion and characterize the compounds using X‐ray diffraction, diffuse reflectance spectroscopy, density functional theory (DFT) calculations along with magnetic
