Abstract In this study, to improve the performance of conventional silicon (Si)-based optoelectronic devices, an Au/FMDD/p-Si/Al Metal-Interlayer-Semiconductor (MIS) structure was successfully fabricated by introducing a new organic interlayer material at the metal-semiconductor interface. In this context, a new fluorene-based aldodioxime derivative, (1E,1’E)-4,4’-((9 H -fluoren-9-ylidene)methyle…

Abstract In this paper, we study Dirac fermions confined in a graphene quantum ring with wedge disclinations under an external magnetic flux. The topological defect is modeled through a conical geometry, inducing effective gauge contributions in the angular sector of the Dirac Hamiltonian. In this case, analytical expressions for the energy spectrum are obtained under infinite-mass boundary condi…

Abstract CuO was synthesized using various metal precursors as Cu 2+ sources via a combined coprecipitation and microwave-assisted hydrothermal method, and its gas-sensing performance was systematically evaluated in relation to its structural, electronic, and morphological properties. This study systematically investigates the role of precursor chemistry as a key parameter in controlling the nucl…

Abstract Electrochemical water splitting is a promising strategy for sustainable hydrogen production; however, it requires efficient and durable non-noble metal electrocatalysts. In this work, we report the controlled synthesis of two-dimensional (2D) CuCo₂O₄ nanosheets (CC-NS) via a Triton X-100-assisted hydrothermal method, highlighting a morphology-engineering approach for enhanced bifunctiona…
