ABSTRACT
Here we propose a universal method for the determination of all helicities present in unidirectional assemblies of hexagon-based graphitic or graphiticlike tubular structures, e.g., multiwalled or bundled carbon nanotubes (CNTs) or boron-nitride nanotubes and their structural analogs. A critical dimension characteristic of a fundamental structural property, i.e., the atomic bond length, is discerned from electron diffraction patterns by which all helicities present in the assemblies are identified. Using this method, we determine the helicity population in a single-walled CNT sample produced by laser ablation technique.

    Abstract. Hexagonal and cubic boron nitride films are deposited by pulsed laser ablation from a boron nitride and a boron target using a KrF excimer laser. Hexagonal films are deposited in nitrogen as background gas or with nitrogen/argon ion bombardment at ion-to-arriving-target-atom (I/A)...

    Ablation of cubic-boron nitride (c-BN) ceramic irradiated by Ti:sapphire laser (110 fs, 790 nm) and Nd:YAG laser (100 ps, 1.064 µm) pulses is comparatively studied. In the case of Ti:sapphire laser ablation, it is observed that the ablation depth per pulse has two different ablation regimes,...
