Recent progress in the laser microprinting of semiconductors and metals

Recently, we published our early results on laser microprinting of functional microelectronics (Nature Commun. 14, 1103 (2023)). Here, we report our progress beyond this work. First, we present a simplified photothermal print scheme – again without the need for post-processing. This scheme includes the purposeful choice of the printing substrate as well as new inks. Second, we present our early results on in-situ monitoring of the metal- and semiconductor-growth processes by time-resolving a weak co-focused reflected probe laser beam. Third, we discuss how the print parameters such as focus speed and laser power influence the morphology of the printed material.
