Abstract

The morphological and structural evolution of WS2 nanosheets under electron irradiation is investigated using high-resolution transmission electron microscopy. During irradiation, the sulfur atoms that interacted with the electrons were sputtered first and the tungsten atoms began to sputter when the surrounding sulfur atoms had been sputtered. With an increasing irradiation time, the remaining tungsten atoms rearranged to form new structures. In addition, the damage to the WS2 nanosheets became more severe with increasing electron energies and irradiation times.

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.
