The goal of the project is to study the influence of the electric fields on the growth of free-standing carbon nanotubes(CNTs) by chemical vapor deposition (CVD) used in field emission (FE) applications. The growths are performed in an environmental transmission electron microscope (ETEM) with the ETEM growths observed in real-time under  C2H2 environment at 700° C  across a polarizable capacitor gap of specifically designed micro-chip sample holders.
