  The recent development of Liquid Phase Exfoliation (LPE) of 2D materials has
enabled the formulation of inks with rheological properties adapted to numerous
liquid deposition methods. This has allowed the fabrication of various types of
printed devices with unique features stemming from the nano-structure of the
printed 2D layers. In this short communication, we demonstrate that the
preferred crystalline orientation of printed MoS2 flakes depends drastically
upon the printing method employed to deposit the layers. Using angle resolved
X-Ray Diffraction (XRD) to measure Pole Figure and subsequently calculate
Orientation Distribution Functions (ODF), we show that the spin-coating method
yields the best basal fiber texture, most likely because of the shear force at
work on the flakes during the deposition process. This interim report thereby
paves the way to further investigations and fine control of the preferred
crystalline orientation of printed 2D flakes for the development of dedicated
devices.
