Non-invasive nanoscale potentiometry and ballistic transport in epigraphene nanoribbons

25 Feb 2020 De Cecco A. Prudkovskiy V. S. Wander D. Berger R. Ganguly C. de Heer W. A. Courtois H. Winkelmann C. B.

The recent observation of non-classical electron transport regimes in two-dimensional materials has called for new high-resolution non-invasive techniques to locally probe electronic properties. We introduce a novel hybrid scanning probe technique to map the local resistance and electrochemical potential with nm- and $\mu$V resolution, and we apply it to study epigraphene nanoribbons grown on the sidewalls of SiC substrate steps...
