Magnetism of two-dimensional triangular nanoflake-based kagome lattices

Abstract: We report a new method for the design of kagome lattices using zigzag-edged triangular graphene nanoflakes (TGFs) linked with B, C, N or O atoms. Using spin-polarized density functional theory we show that the electronic and magnetic properties of the designed kagome lattices can be modulated by changing their size and the linking atoms. The antiferromagnetic coupling between the two directly linked TGFs becomes ferromagnetic coupling when B, C or N is used as the linking atoms, but not for O atom linking. All… Show more

“…This interesting etching phenomena can be significant to create well-defined etched hole and growing other 2D structure such as graphene and thereby realizing in-plane heterostructure. Moreover, controlled etching of continuous h-BN film with ordered structures can be feasible to develop kagome like lattices for spintronic applications 44 .…”

“…[16,17] Given their high-spin ground states, interesting fundamental and technological prospects lie in the construction of one-dimensional chains and two-dimensional networks incorporating TZNGs as building blockssuch as the discovery of elusive quantum states of matter [18] and room-temperature long-range magnetic ordering. [19][20][21] With the advent of on-surface synthesis as a chemical toolbox, [22] fabrication of extended TZNG nanostructures seems feasible on metal surfaces, given the proper chemical precursor design. Figure 1 illustrates the versatility of TZNG nanostructures.…”

“…A range of applications have been envisaged for TZNGs in molecular electronics and spintronics such as spin filters, [13, 14] qubits for quantum information processing, [15] and electrically controllable magnetic switches [16, 17] . Given their high‐spin ground states, interesting fundamental and technological prospects lie in the construction of one‐dimensional chains and two‐dimensional networks incorporating TZNGs as building blocks—such as the discovery of elusive quantum states of matter [18] and room‐temperature long‐range magnetic ordering [19–21] . With the advent of on‐surface synthesis as a chemical toolbox, [22] fabrication of extended TZNG nanostructures seems feasible on metal surfaces, given the proper chemical precursor design.…”
