Carbon-Coated Te-Doped Bi₂Se₃ as a Topological Quantum Anode Material for Sodium-Ion Batteries
Abstract: Sodium-ion batteries (SIBs) are increasingly investigated as cost-effective alternatives to lithium-ion systems for large-scale energy storage; however, the development of stable and conductive anode materials remains a major challenge. In this work, tellurium-doped bismuth selenide (Te-doped Bi₂Se₃) was synthesized and further modified with Super P conductive carbon to improve its sodium-storage behavior. The phase formation and structural retention of the active material were examined using X-ray diffraction, while elemental mapping …

Bismuth-Doped CuGaS₂ Thin Films for Enhanced Photovoltaic and Electrocatalytic Performance
Abstract: This study presents the development and application of bismuth (Bi)-doped CuGaS₂ thin films for enhanced performance in photovoltaic and electrocatalytic systems. Using a cost-effective all-solution processing method, Bi-doped CuGaS₂ chalcopyrite nanocrystals were synthesized and spray-deposited onto molybdenum substrates. The resulting films, with a thickness of approximately 730 nm and grain sizes larger than 400 nm, exhibited superior optical properties and a lower band gap compared to undoped films, making them …
