BiSbF2 Monolayer: A 2D Inversion‐Asymmetric Topological Insulator With Linearly Tunable Giant Spin‐Splitting and Bulk Gap

Advanced Electronic Materials, EarlyView.
The BiSbF2 monolayer is a 2D topological insulator with a large bandgap (252 meV) hosting topological edge states and giant valley‐contrasted spin‐splitting (478 meV). The sizable gap enables room‐temperature quantum spin Hall effects, while its coexisting topological and valleytronic features provide a versatile platform for exploring topological ...

Enhancing Thermoelectric Performance of Cd₃P₂ by Alloying with Dirac Material Cd₃As₂

Advanced Electronic Materials, EarlyView.
This study demonstrates that alloying Cd₃P₂ with Dirac material Cd₃As₂ significantly enhances its thermoelectric performance. Key improvements include increased carrier mobility, reduced effective mass, and lower deformation potential, resulting in a doubled power factor and improved thermoelectric efficiency, which renders this material applicable for
