AB  - The one-dimensional (1D) acceptor-donor (A-D) hetero-nanotube (HNT) has attracted 
      much attention as a potential candidate for a channel structure of 
      next-generation field effect transistors (FETs). Herein, we designed A-D 
      C(3)N/C(3)B double-wall (dw) HNTs by coaxially wrapping C(3)N and C(3)B nanotubes 
      together. By using density functional theory (DFT) combined with the 
      nonequilibrium Green's function (NEGF) formalism, we studied the electronic 
      properties and ballistic transport behavior of C(3)N/C(3)B dwHNTs in comparison 
      with the ones in vertical stacking contact. The remarkable charge transfer 
      between C(3)N and C(3)B nanotubes and band hybridization in C(3)N/C(3)B dwHNTs 
      originate from the strong intertubular pi-pi stacking interaction. In the simulated 
      all-around-gated FET devices, (12,0) C(3)N/(6,0) C(3)B dwHNT with 2 repeated 
      wrapping units possesses the optimal performance, including rectifying ratio and 
      subthreshold swing (SS), by enhancing the A-D asymmetry. Our work suggests that 
      coaxial wrapping is a method superior to vertical stacking in constructing A-D 
      HNTs for high-performance electronic and optoelectronic devices based on 1D 
      materials.
