Researchers have developed a groundbreaking 3D laser printing method for single-crystalline zinc oxide (ZnO) structures with sub-micrometer precision, eliminating the need for cleanrooms or complex post-processing. The team, including Cluster Doctoral Researchers Matthias Steurer, Kristian Kraft, Steven Kraus, Postdoctoral Researchers Paul Somers, Lukas Grünewald, Florian Feist, and PIs Prof. Dr. Stefanie Dehnen, Yolita M. Eggeler, Christopher Barner-Kowollik, and Martin Wegener, optimized the process with DMSO and tailored substrates to improve heat management and light absorption. This innovation enables precise printing, opening new possibilities for microelectronics and optics, such as nanowire transistors and microlasers.
