Two-dimensional (2D) semiconductors offer great potential in nanoelectronics due to their unique electrical and optical properties mainly attributed to their atomically thin nature. To make use of 2D semiconductors for practical applications, it is highly desired to develop scalable methods for integration of complementary circuits rather than a discrete device. We report a simple, scalable method for fabricating complementary inverters based on n-type monolayer MoS 2 , grown by a chemical vapor deposition (CVD), and inkjet-printed p-type SWCNTs. The CVD and inkjet printing methods are effectively combined to show the feasibility in terms of the integration of low-dimensional materials for complementary circuits. In the complementary circuits, cost-effectively printed Ag is utilized as the source and drain electrodes for both MoS 2 and SWCNT transistors. Both the n- and p-type transistors show decent device characteristics at low operating voltages under ambie…
