## Description

- description: One-dimensional (1D) nanoribbons of transition metal dichalcogenides
    (TMDs) are predicted to exhibit exotic quantum phenomena that make them attractive
    for use in nanoscale electronic and spintronic devices. However, exploring the
    potential of ultranarrow TMD nanoribbons remains a challenge due to the lack of
    a suitable platform. Here, we report the atomically precise growth of ultranarrow
    MoS2 nanoribbons within boron nitride nanotubes (BNNTs). The insulating nature
    of BNNTs enables direct optical probing of the encapsulated species without perturbing
    their intrinsic properties. Atomic-resolution transmission electron microscopy
    reveals the preferential growth of bilayers along the zigzag direction. Raman
    spectra confirm that the encapsulated structures experience significant strain.
    Angle-resolved polarized Raman spectroscopy reveals strong optical anisotropy
    in the 1D geometry, markedly distinct from that of the isotropic 2D MoS2 sheets.
    Our approach offers an ideal platform for exploring intrinsic optical properties
    and device applications in ultranarrow TMD nanoribbons.
