AI Technical Summary
Existing technologies struggle to achieve high-precision, reproducible patterned growth of large-area, high-quality two-dimensional transition metal chalcogenides, and the control of precursors during the growth process is difficult to achieve quickly, stably, and controllably.
Using a commercial flatbed inkjet printer and a self-made XY heating stage, patterns are printed on the growth substrate by inkjet printing water-based precursors. Combined with CVD equipment and magnets to move the sample quickly, high-precision control of growth temperature and patterning is achieved. Custom quartz rods and ring magnets are used to move the sample for rapid heating. Water-based precursor solutions with printable inks are prepared to reduce surface tension and viscosity.
Rapid growth of large-area, high-quality two-dimensional transition metal chalcogenides was achieved, with carrier mobilities reaching 21 cm2V-1s-1 and 54 cm2V-1s-1. This simplified experimental procedures, reduced human error, and extended the application to other high-temperature substrates.
