'Etch-a-Sketching' critical p-n nano-junctions for 2D Semiconductor diode

Elisa Riedo, professor at the New York University (NYU) Tandon school of Engineering led an international team that used thermal scanning probe lithography (t-SPL) to fabricate state-of-the-art "p-n junctions" on a single atomic layer of molybdeunum disulfide (MoS2) a transition metal dichalcogenide. The work, 'Spatial defects nanoengineering for bipolar conductivity in MoS2,' appears in Nature Communications.
