• -)electronic and catalytic functionality [14][15][16][17][18]. Ion irradiation has already proven effective for defect engineering across different energy regimes: Low-energy ions enable implantation with near-atomic precision [19][20][21], kiloelectronvolt ions primarily create point defects in monolayers [22

This grid enables ions to decelerate and traverse a field-free region near the source, ensuring minimal perturbations to the ion beam and facilitating precise ion transport.

• ), backscattered He (BSHe), and sometimes photons are created. Image acquisition is done by collecting SEs with an Everhardt–Thornley (ET) detector. Due to the nature of the interaction of low-energy ions with matter, the lateral size of the interaction volume in the immediate vicinity of the surface remains
