abstract = {Layered transition metal di-chalcogenide (TMD) materials
exhibit a unique combination of structural anisotropy
combined with rich chemistry that confers controllability
over physical properties such as bandgap and magnetism. Most
research in this area is focused on single layers that are
technologically challenging to produce, especially when
trying to dope and alloy the host lattice. In this work, we
use MoS2 flakes as a model system for the production of
deliberately oriented films for practical applications in
which anisotropic materials are required. The proposed
production method combines ball milling with exfoliation in
solution of MoS2 flakes, followed by their arrangement on a
large centimeter-scale substrate by a simple and
non-expensive procedure. The results show that the level of
orientation achieved using the proposed system is as good as
that of materials that were pressed and subjected to thermal
treatment. The ball milling and exfoliation processes
maintain the original crystalline structure of the MoS2
flakes, and the XRD results show that additional
crystallographic phases were not produced. Lattice
parameters are preserved, which verifies that other species
such as water molecules did not intercalate into the MoS2
molecules. The proposed method of producing oriented films
is universal, and as such, it is useful both for pure
materials and for mixtures of compounds, the latter of which
can be used to produce films with specifically tailored
physical properties.},
