Field　emission　holds　significant　promise　for　diverse　applications　in　the　field　of　vacuum　microelectronic　devices,　and　the　development　of　flexible　materials　for　high-performance　field　emission　electron　sources　is　of　great　value.　In　this　study,　ZnO/TiC　nanorod　arrays　with　the　shell-core　structure　were　constructed　on　the　surface　of　flexible　carbon　fibers　via　magnetron　sputtering.　The　composition　and　microstructure　of　the　TiC　film　were　precisely　regulated　by　varying　the　carbon　target　power　(50–80　W).　Various　characterization　methods,　such　as　XRD,　SEM,　EDS,　and　XPS,　were　applied　to　investigate　the　phase　composition　and　morphology　of　ZnO/TiC　composite　structures.　The　results　showed　that　the　carbon　target　power　had　an　important　effect　on　the　composition　and　microstructure　of　the　TiC　shell　layer.　The　results　show　that　the　samples　prepared　with　a　carbon　target　power　of　60　W　exhibit　optimal　field　emission　performance,　with　low　turn-on　field　strength　(∼3.6　V/μm)　and　high　field　enhancement　factors　(∼2831),　which　are　ascribed　to　the　synergistic　effects　of　the　TiC　shell　layer＇s　high　crystallinity　and　good　electrical　conductivity,　as　well　as　the　uniform　diameters,　optimized　aspect　ratios,　and　perpendicular　orientations　of　the　ZnO　nanorods.　This　study　provides　a　new　idea　for　surface　optimization　of　shell-chore　nanostructured　materials　and　lays　the　technical　foundation　for　the　development　of　high-performance　flexible　field　emission　microelectronic　devices.　©　2025
