Spin polarization plays an important role in spintronics, nanoelectronics, new energy, and other emerging high-tech fields. However, due to the lack of suitable research targets and insufficient understanding of the...

Magnetic field enhancement of the FeCoSe2 photoanode for the oxygen evolution reaction by adjusting the hole density to reduce competitive adsorption between Fe and Co in a photoelectrochemical water-splitting system

“…Previous studies have shown that materials with electron spin structure can produce mixed phases with direct and indirect band gaps due to the influence of electron spin. 27 In the case of the synthesized materials, Tauc plot (Fig. 4b and d) analysis revealed that both direct and indirect bandgap CoSe 2 were smaller than those of FeSe 2 and FeCoSe 2 .…”

The Structural and Electrochemical Properties of CuCoO2 Crystalline Nanopowders and Thin Films: Conductivity Experimental Analysis and Insights from Density Functional Theory Calculations

“…Among various delafossite oxides, copper-based delafossite oxides stand out as promising candidates due to their desirable electrical and optical characteristics. The copper-based delafossite oxide, specifically CuMO 2 (where M represents Al, Ga, Fe, Co, Mg, Fe, Cr…), has attracted considerable attention for diverse applications such as batteries [ 9 , 10 , 11 , 12 , 13 , 14 , 15 ], luminescent materials [ 16 , 17 , 18 , 19 , 20 , 21 ], thermoelectrics [ 22 , 23 , 24 , 25 , 26 , 27 , 28 ], solar energy conversion and photocatalysis [ 29 , 30 , 31 , 32 , 33 , 34 , 35 ], hydrogen production through water splitting using photocathodes [ 36 , 37 , 38 , 39 , 40 , 41 ], and gas sensors [ 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 ]. In this study, we focus on the CuCoO 2 compound, in view of intriguing structural, optical, and electrical properties; it has only been studied in a limited number of publications, and in most of them, the CuCoO 2 compound has shown interesting properties to be treated as a possible material in photovoltaic solar cells [ 50 ,…”
