Unraveling the Orientation-Dependent Electrical Anisotropy of Chemical Vapor Deposited Layered CoTe ₂ Nanostructures

2̅7̅) nanoribbons and vertically aligned van der Waals gaps in (11̅0) nanoflakes reduced electron transport efficiency by 5.1 and 1.4 times compared to that of in-plane transport conditions, which result from weak charge hopping across the van der Waals gap and strong charge drift ability along in-plane chemical bonds. This work overcomes the bottleneck of traditional layer-by-layer horizontal growth of the (001) plane, providing a theoretical and experimental framework for designing anisotropic electronic devices based on thermodynamically unstable crystallographic planes.
