摘要：SummaryHigh-performance van der Waals (vdW) integrated electronics and spintronics require reliable current-carrying capacity. However, it is challenging to achieve high current density and air-stable performance using vdW metals owing to the fast electrical breakdown triggered by defects or oxidation. Here, we report that spin-orbit interacted synthetic PtTe2layers exhibit significant electrical reliability and robustness in ambient air. The 4-nm-thick PtTe2synthesized at a low temperature (∼400°C) shows intrinsic metallic transport behavior and a weak antilocalization effect attributed to the strong spin-orbit scattering. Remarkably, PtTe2sustains a high current density approaching ≈31.5 MA cm−2, which is the highest value among electrical interconnect candidates under oxygen exposure. Electrical failure is caused by the Joule heating of PtTe2rather than defect-induced electromigration, which was achievable by the native TeOxpassivation. The high-quality growth of PtTe2and the investigation of its transport behaviors lay out essential foundations for the development of emerging vdW spin-orbitronics.Graphical abstractDisplay OmittedHighlights•The synthesized PtTe2had a self-passivated surface under exposure to air•Magnetoconductance study proved the realization of a 2D confined quantum system•PtTe2sustained a remarkably high current density (∼31.5 MA cm−2) under air atmosphere•The native TeOxpassivation retarded the defect-induced electromigration of PtTe2Condensed matter physics; Nanomaterial
