Abstract
Epitaxial graphene nanoribbons have recently demonstrated exceptional one dimensional ballistic transport where charge carriers can travel without scattering up to 16 m at
room temperature (STM probes in UHV). These transport properties are not yet fully understood, and they can only be exploited if nanoribbons can be produced at large scale with
good properties in ambient conditions. Following up on these results, in this thesis I will summarize my work on arrays of epitaxial graphene nanoribbons grown on the sidewalls
of trenches and steps of silicon carbide. I will discuss nanoribbon growth, nanofabrication, factors that affect nanoribbon transport and how mean free paths larger than one micron are consistently found at room temperature for thousands of nanoribbons.
