Graphene nanoribbon (GNR) has attracted much attentions as a new novel conductive nanowire. GNR can be fabricated by unzipping carbon nanotubes (CNT). However, the unzipping process is not clear. In this study, we challenge to understand the unzipping mechanism using home-built ultra-high vacuum (UHV) scanning tunneling microscopy (STM). CNT/GNR solution was sprayed in vacuum on an atomically-flat clean Cu(111) surface. We will report how the CNT deform or unzip with an application of voltage, current, heat, electric field and force.
