Engineering the electronic structure of 1T′-ReS2 through nitrogen implantation for enhanced alkaline hydrogen evolution

Controllable atomic engineering of N into 1T′-phase ReS2 regulates the electronic structure and leads to enhanced alkaline hydrogen evolution.

Engineering single-atom dynamics with electron irradiation

Atomic engineering is envisioned to involve selectively inducing the desired dynamics of single atoms and combining these steps for larger-scale assemblies. Here, we focus on the first part by surveying the single-step dynamics of graphene dopants, primarily phosphorus, caused by electron irradiation both in experiment and simulation, and develop a theory for describing the probabilities of competing configurational outcomes depending on the postcollision momentum vector of the primary knock-on atom. The predicted branching ratio of configurational transformations agrees well with our atomically resolved experiments. This suggests a way for biasing the dynamics toward desired outcomes, paving the road for designing and further upscaling atomic engineering using electron irradiation.
