In a collaborative effort between the Charles University of Prague, CFM (CSIC-UPV/EHU) center in San Sebastian, and CIC nanoGUNE’s Nanodevices group, a groundbreaking discovery has been made in the field of spintronics. The research has resulted in the design of a new complex material with remarkable properties, as outlined in a recent publication in Nature Materials. This finding has the potential to revolutionize the development of electronic devices, particularly in the integration of magnetic memories into processors.
The exploration of two-dimensional materials with unique characteristics has garnered significant interest in the scientific community. When two layers of these materials are stacked to create a heterostructure, novel effects are observed. Recent studies have revealed that even minute rotations of these layers can lead to substantial changes in the properties of the heterostructure. This phenomenon has paved the way for exciting advancements in the field of material science.
One of the key findings of this research involves the stacking of two layers of graphene and tungsten selenide (WSe2). By precisely aligning and rotating these layers, researchers were able to generate a spin current in a specific direction. Traditionally, spin, a fundamental property of electrons and other particles, is transferred perpendicular to the electric current. This poses a significant challenge in spintronics applications. However, the study conducted by the Nanodevices group at nanoGUNE has demonstrated that by harnessing specific material combinations and employing controlled rotational angles, new spin-related properties can be achieved.
The implications of this discovery are far-reaching for the field of spintronics. The ability to manipulate spin currents through material design opens up new possibilities for the development of advanced electronic devices. By overcoming the traditional limitations associated with spintronics, such as the challenge of handling spin currents, researchers can now explore innovative applications in information storage, processing, and transfer. The prospect of obtaining unique spin-related properties through precise material engineering represents a significant milestone in the quest for more efficient and effective electronic technologies.
The collaborative research effort between leading institutions has led to a paradigm shift in the field of spintronics. The creation of a complex material with emergent properties through the stacking of two-dimensional layers marks a crucial advancement in material design. With this breakthrough, the future of spintronics appears brighter than ever, promising a new era of innovation and technological advancement.
