Low-dimensional carbon nitrides are expected to exhibit rich structural diversity and tunable electronic properties;however,their controlled synthesis remains challenging.Here,we demonstrate the synthesis of one-and two-dimensional carbon nitride phases on Cu(111)using ion-beam-assisted epitaxy.By systematically tuning the growth parameters,two distinct ordered phases are selectively stabilized:a two-dimensional 6×6 superstructure and a one-dimensional chain-like phase.Their structural and electronic properties are investigated using scanning tunneling microscopy,low-energy electron diffraction,x-ray photoelectron spectroscopy,and angle-resolved photoemission spectroscopy.The combined measurements provide clear evidence for C-N bond formation and semiconducting behavior in both phases.These results establish ion-beam-assisted epitaxy as an effective route for realizing low-dimensional carbon nitrides and provide a platform for exploring low-dimensional electronic and optoelectronic devices. 展开更多
