Meanwhile, strain significantly enhances the anisotropy of electronic states, enabling direction-dependent effective-mass modulation and carrier mobility. Under externally applied electric fields, the stacking configurations exhibit different band-structure responses, originating from field-driven modulation of the interlayer potential and charge redistribution. Moreover, the heterostructures indeed exhibit excellent optical absorption from the near-infrared to the far-ultraviolet region, with the external electric field enabling controllable spectral tuning.

To address this challenge, we propose a reactive impregnation wetting strategy for creating heat transfer channels between VACNTs and metals. By introducing a reactive element (i.e., Ti), we promote the impregnation wetting of a high-thermal-conductivity liquid alloy into the array, simultaneously ensuring robust bonding between the VACNTs and smooth copper foils. The resulting Cu-VACNTs-Cu sandwich structure exhibits remarkable thermal transport properties, achieving through-plane of 18.8 W·m⁻1·K⁻1 which represent 2.4-fold improvements compared to pristine VACNTs. Moreover, the contact thermal resistance of our structure is approximately one-third that of pristine VACNTs in direct dry contact with the device.
