Modified Transition Metal Dichalcogenides: Manipulation of Magnetism
Abstract
OverviewThe four investigators: Drs. Munkhsaikhan, Otgonbayar and Ganchimeg (Mongolian University of Science and Technology), and Dr. Odkhuu (Incheon National University) propose to induce and manipulate the magnetism by compositional and structural modificationsof otherwise nonmagnetic 2D TMDs crystals, MoSe2 and WSe2, in connection with doping with rare-earth atoms (Nd and Sm), complemented by a high-throughput computational investigation. This project involves three research teams composed of 14 researchers located inthree different countries. The total estimated project cost is $286,315.41 for a period of 3 years.Intellectual MeritTwo-dimensional (2D) Transition Metal Dichalcogenides (TMDs) have been the focus of numerous theoretical, experimental, and technological advances, such as the study of topology, fluctuation-driven generation of new phases, electrical manipulation of magnetism, and spintronics, where spin fluctuations are expected to increase significantly. These modified structures will be designed for commercial applications to satisfy the current demand for maximizing information storage density in magnetic memories. Specifically, the present studyaims to fill an existing knowledge gap in the possible fabrication of TMD alternatives, to report the effects of doping with rare-earth elements (Nd and Sm), and to improve the atomic level fundamental understanding of the relationship between structural, electronic and magnetic properties of the newly developed 2D magnetic materials.Broader ImpactsThe doping engineering of 2D TMDs by rare-earth atoms is a relatively new area to the PIs. The collaborative research project will represent a step toward integrating the PI#s capabilities with colleagues in physical and information sciences, and abroad (South Korea and the USA). None of our previously funded work was collaborative. The proposed project will support four graduate students, one postdoctoral fellow, and seven investigators. This collaborative research is expected to have a significant positive impact on climate and culture of the School of Applied Sciences, of which four of the investigators are faculty members.
