Structure-modified stress dynamics and wetting characteristics of carbon nanotubes and multilayer graphene for electron field emission investigations

, : Structure-modified stress dynamics and wetting characteristics of carbon nanotubes and multilayer graphene for electron field emission investigations. Acs Applied Materials & Interfaces 6(15): 12531-12540

In the present work, feasibility of achieving enhanced electron field-emission properties of stress-induced carbon nanotubes (CNTs) and multilayer graphene (MLGs) by ion modification is studied. Micro-Raman spectroscopy is used as a potent technique for in-depth investigations of stress-induced CNTs and MLGs. It is found that iron used as a catalyst, compresses at particular fluence and induces stresses in CNTs and MLGs to modify these structures, supported by high-resolution transmission electron microscopy (HRTEM) studies. The stresses are explained by the buckling wavelength (λ ∝ e((r/t)0.5)). Furthermore, the stresses induced in exotic nanostructures are studied for investigating wetting properties, which are well-corroborated with electron emission characteristics. It is found out that less-wetted CNTs and MLGs display enhanced emission properties with turn-on voltages (Eon) of 1.5 and 2.1 V/μm, respectively, in comparison to hydrophilic CNTs and MLGs with Eon of 2.6 and 4 V/μm, respectively.
