Selective focused-ion-beam sculpting of TiO2nanotubes and mechanism understanding
Literature Information
Bo Chen, Kathy Lu
Anodic TiO2 nanotubes with different structures, doping agents, and decorations have been studied in order to improve energy conversion and storage efficiencies such as in dye sensitized solar cells, solar fuels, and electrochemical supercapacitors. However, the top surface modification of TiO2 nanotubes has never been addressed. In this study, anodic TiO2 nanotubes have been selectively closed by high energy focused ion beams and re-opened by low energy focused ion beams. Under a 30 kV Ga+ beam, TiO2 nanotubes are closed with a 65 nm shield layer covering the top entrance when the ion dose is larger than 1.2 × 1017 ions per cm2; under a 5 kV Ga+ beam, the shield layer is removed and the closed tubes are re-opened. An ion-induced viscous flow model has been proposed to explain the influence of Ga+ ion beam flux, substrate temperature, initial tube diameter, ion beam dwell time, and the incidence angle of the ion beam.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
