“…The behavior of 2D materials can be further controlled via chemical or electrostatic doping. 1 , 2 Moreover, van der Waals (vdW) heterostructures show emergent behavior based on interfacial effects, including orbital hybridization, 3 − 5 magnetic interactions, 6 and proximal superconductivity. 7 Work function-mediated interlayer charge transfer offers another route to realizing novel interfacial phenomena.…”

Nanoscale charge control is a key enabling technology in plasmonics, electronic band structure engineering, and the topology of two-dimensional materials. By exploiting the large electron affinity of α-RuCl 3 , we are able to visualize and quantify massive charge transfer at graphene/α-RuCl 3 interfaces through generation of chargetransfer plasmon polaritons (CPPs). We performed nanoimaging experiments on graphene/α-RuCl 3 at both ambient and cryogenic temperatures and discovered robust plasmonic features in otherwise ungated and undoped structures. The CPP wavelength evaluated through several distinct imaging modalities offers a high-fidelity measure of the Fermi energy of the graphene layer: E F = 0.6 eV (n = 2.7 × 10 13 cm −2 ). Our first-principles calculations link the plasmonic response to the work function difference between graphene and α-RuCl 3 giving rise to CPPs. Our results provide a novel general strategy for generating nanometer-scale plasmonic interfaces without resorting to external contacts or chemical doping.

“…Since the discovery of transport properties in graphene [8,9], new physical phenomena of 2D materials are being continuously revealed in a wide range of fields [10][11][12]. As for magnetism, intrinsic magnetic order in the monolayer/few-layer limit was firstly experimentally realized in 2D ferromagnets Cr 2 Ge 2 Te 6 and CrI 3 in 2017, after which various 2DMMs have been rapidly discovered and studied [13,14].…”

The emergence of low-dimensional nanomaterials has brought revolutionized development of magnetism, as the size effect can significantly influence the spin arrangement. Since the first demonstration of truly two-dimensional magnetic materials (2DMMs) in 2017, a wide variety of magnetic phases and associated properties have been exhibited in these 2DMMs, which offer a new opportunity to manipulate the spin-based devices efficiently in the future. Herein, we focus on the recent progress of 2DMMs and heterostructures in the aspects of their structural characteristics, physical properties, and spintronic applications. Firstly, the microscopy characterization of the spatial arrangement of spins in 2D lattices is reviewed. Afterwards, the optical probes in the light-matter-spin interactions at the 2D scale are discussed. Then, particularly, we systematically summarize the recent work on the electronic and spintronic devices of 2DMMs. In the section of electronic properties, we raise several exciting phenomena in 2DMMs, i.e., long-distance magnon transport, field-effect transistors, varying magnetoresistance behavior, and (quantum) anomalous Hall effect. In the section of spintronic applications, we highlight spintronic devices based on 2DMMs, e.g., spin valves, spin-orbit torque, spin field-effect transistors, spin tunneling field-effect transistors, and spin-filter magnetic tunnel junctions. At last, we also provide our perspectives on the current challenges and future expectations in this field, which may be a helpful guide for theorists and experimentalists who are exploring the optical, electronic, and spintronic properties of 2DMMs.
