Abstract :
Contacting carbon nanotubes (CNTs) and graphene with nanometer-scale metals is of great interest for both fundamental studies and technical applications. In this work, we describe the fabrication and characterization of sub-5 nm linewidth metallic hafnium diboride (HfB2) nanostructures on silicon surfaces as well as on CNTs and graphene using scanning tunneling microscopy (STM) and spectroscopy (STS).
