dc.description.abstract | Liquid-phase exfoliation (LPE) has been introduced as a versatile and scalable production method for
two-dimensional (2D) materials. This method yields dispersions that allow for the fabrication of printable
and flexible electronic devices. However, the fabrication of uniform and homogeneous films from LPE
dispersions with a performance similar to that of bottom-up grown materials remains a challenge, as the
film quality strongly influences the optical and electrical performance of devices. Furthermore, longterm stability remains a major challenge for all 2D material based applications. In this study, we report
on highly conductive tiled network films made of platinum diselenide (PtSe2) flakes derived using a
scalable LPE method. We characterized the homogeneous films in terms of morphology and electrical
behavior. As an example of applicability, we produce a chemiresistive sensor structure with the PtSe2
films and show significant resistance changes upon periodic ammonia gas exposures, revealing a sub0.1 part per million (ppm) detection limit (DL). More remarkably the devices are fully functional after
15 months, underlining the high stability of PtSe2 based devices | en |
