## Description

- description: 'One-dimensional (1D) van der Waals materials have emerged as an intriguing
    playground to explore novel electronic and optical effects. We report on inorganic
    one-dimensional SbPS4 nanotubes bundles obtained via mechanical exfoliation from
    bulk crystals. We find that SbPS4 can readily be exfoliated to yield > 10 µm long
    nanobundles with typical diameters and thicknesses of 10 - 200 nm. SbPS4 is a
    direct gap semiconductor with an electronic band gap of ~2.5-3 eV. We investigated
    the optical response of SbPS4 nanobundles and discovered that upon excitation
    with 3.06 eV (405 nm) light, they emit extremely broad photoluminescence (PL)
    from ~1.2-1.9 eV with a quantum yield similar to that of hBN-encapsulated MoSe2.
    Using density functional theory, we calculate electronic and vibrational structure
    of the SbPS4 nanotubes, as well the strength of electron-phonon coupling.  The
    measured Raman spectra of SbPS4 exhibits numerous low (< 300 cm-1) wavenumber
    Raman modes, which coincide in energy with the calculated vibrational modes with
    strong electron-phonon coupling. The large difference between the absorption and
    PL emission energies is explained by a large ~1 eV electron-hole binding energy
    and a ~200 meV self-trapping effect due to the coupling to vibrational degrees
    of freedom. The ability to mechanically exfoliate SbPS4 nanobundles offers the
    possibility of applying modern 2D material fabrication techniques to create mixed-dimensional
    van der Waals heterostructures. Due to the bright and ultra-broadband PL, we believe
    that this class of 1D semiconductors has numerous potential applications including
    on-chip tunable nanolasers, and lighting applications that require ultra-violet
    to visible light conversion. '
