Development of inkjet printing technology for MoS2

Researchers at KTH Royal Institute of Technology have developed a simple and efficient inkjet printing technology for molybdenum disulfide (MoS2), which is one of the most attractive two-dimensional layered materials. The technology efficiency facilitates the integration of printed MoS2 patterns with other components (such as electrodes), and hence allows fabricating various functional devices, including thin film transistors, photoluminescence patterns, and photodetectors, in a simple, massive and cost-effective manner while retains the unique properties of MoS2.

As compared with the initial MoS2/DMF dispersion in (a), the MoS2/terpineol ink is first concentrated by 20 times via distillation and then tailored by ethanol at the volume ratio of terpineol:ethanol = 3:1. c) Absorbance spectra for the MoS2 ink in (b) diluted by 20 times with terpineol.
