Fabrication of high-quality 2-dimensional material single crystal nanoribbon networks — •Muhammad Awais Aslam¹, Markus Kratzer¹, Christian Teichert¹, Raul David Rodriguez², and Aleksandar Matković¹ — ¹Institute of Physics, Montanuniversität Leoben, Leoben, Austria — ²Tomsk Polytechnic University, Tomsk, Russia

We demonstrate an approach to synthesize 2D material nanoribbon networks. The epitaxially grown organic nanostructures align predominantly in either zig-zag or armchair orientation on 2D materials. 1,2 This study demonstrates their usage as a mask. These hybrid heterostructures are plasma etched to form single crystal nanoribbon networks. Raman spectroscopy and atomic force microscopy are employed to verify the quality of the ribbons. Our method opens up a new avenue for straightforward production of 2D material nanoribbon networks on scales relevant to electronic applications. Their high edge-to-surface ratios will also be of technological relevance for the development of future light and chemical sensors.
