Van der Waals (vdW) heterostructures have received intense attention for their efficient stacking methodology with 2D nanomaterials in vertical dimension. However, it is still a challenge to scale down the lateral size of vdW heterostructures to the nanometer and make proper contacts to achieve optimized performances. Here, a carbon‐nanotube‐confined vertical heterostructure (CCVH) is employed to...
A vertical point heterostructure (VPH) is constructed by sandwiching a two‐dimensional (2D) MoS2 flake with two cross‐stacked metallic single‐walled carbon nanotubes. It can be used as a field‐effect transistor with high on/off ratio and a light detector with high spatial resolution. Moreover, the hybrid 1D–2D–1D VPHs open up new possibilities for nanoelectronics and nano‐optoelectronics.
