Marvin M. Jansen, PhD student in the group of Alexander Pawlis at PGI-9 of the Forschungszentrum Jülich, successfully published his findings in ACS Appl. Nano Mater.

His work entitled “Phase-Pure Wu​rtzite GaAs Nanowires Grown by Self-Catalyzed Selective Area Molecular Beam Epitaxy for Advanced Laser Devices and Quantum Disks” demonstrates the advanced control of self-catalyzed molecular beam epitaxy of GaAs nanowires (NW) with up to a grade of 100% wurtzite (WZ) phase purity. The self-catalyzed growth of such NWs may pave the way for substantial improvement of GaAs NW laser devices, the controlled growth of WZ/ZB quantum disks, and novel heterostructured core/multishell NW systems with a pristine crystalline order.
