“…The crystal lattice of Sb2Te3 and Bi2Te3 is formed by periodically ordered layers perpendicular to the axis of symmetry of the third order (C3) and corresponds to a rhombohedral structure with the point group m R3 . The crystal structure of In4Se3 corresponds to the point group Pnnm(D2h 12 ). The chemical bond within the layer is covalent-ionic.…”

The properties of layered transition metal dichalcogenides intercalated with 3d metal ions are investigated. The influence of the gradient magnetic field at the intercalation front on the properties of intercalants is studied. It is shown that Co0.1Sb2Te3, Ni0.1Bi2Te3 and Ni0.2In4Se3 intercalates have ferromagnetic properties at room temperature. The dependences of the magnetic moment on the magnetic field strength along and across the layers of Co0.1Sb2Te3, Ni0.1Bi2Te3 and Ni0.2In4Se3 intercalates have the hysteresis loop. The obtained values of the coercive force of the studied samples are typical for hard ferromagnets. The properties of the obtained intercalates are determined by the crystal structure of layered crystals, localization and magnetic interaction of intercalant atoms between the layers of the crystal matrix and the influence of the magnetic field on the processes of exchange interaction between them.

“…For example, pristine GaSe flake is a n‐type semiconductor, while the Co‐intercalated GaSe exhibits strong ferromagnetic behavior. [ 75 ] The electrochemical intercalation of Co ions into GaSe was carried out by the method of pulling electric field. The ratio between the width of GaSe interlayer space and the cobalt ion radius makes it possible to incorporate Co ions into the interlayer space of GaSe.…”

In van der Waals (vdWs) materials and heterostructures, the interlayers are bonded by weak vdWs interactions due to the lack of dangling bonds. The vdWs gap at the homo‐ or heterointerface provides great freedom to enrich the tunability of electronic structures by external intercalation of foreign ions or atoms at the interface, leading to the discovery of new physics and functionalities. Herein, the recent progress on electrochemical intercalation of foreign species into atomically thin vdWs materials for structural phase transition and device applications is reviewed and future opportunities are discussed. First, several kinds of electrochemical intercalation platforms to achieve the intercalation in vdWs materials and heterostructures are introduced. Next, the in situ characterization of electrochemical intercalation dynamics by state‐of‐the‐art techniques is summarized, including optical techniques, scanning probe techniques, and electrical transport. Moreover, particular attention is paid on the experimentally reported phase transition and multifunctional applications of intercalated devices. Finally, future applications and challenges of intercalation in vdWs materials and heterostructures are proposed, including the intrinsic intercalation mechanism of solid ion conductors, exact identification of intercalated foreign species by near‐field optical techniques, and the tunability of intercalation kinetics for ultrafast switching.
