Накратко на български

Хексагоналният борнитрид и борофенът се комбинират в хибридни наноструктури, за да се променят техните магнитни и проводими свойства. Това помага за преодоляване на недостатъците на материалите и подобрява технологичните приложения в електрониката.

Engineering magnetic properties of hexagonal boron nitride - based hybrid nanoarchitectures

Beyond graphene, a wide variety of other 2D materials have been discovered after the isolation of graphene in 2004, being hexagonal boron nitride (hBN) and borophene two particularly interesting examples because of their complementary properties. Made of alternating boron and nitrogen, hBN owes excellent chemical stability but cannot be used as a switching unit in electronics because of its large band-gap, while borophene, made of boron, is an outstanding conductor but degrades easily. Therefore, it is imperative to investigate new ways to engineer their properties in order to overcome their limitations while exploiting their superb characteristics. The study of low-dimensional materials, like hBN and borophene, lies at the frontier between materials science, condensed matter physics and physical chemistry. Therefore, the outcome of such interdisciplinary studies are meant to contribute to both basic research and technological applications. In particular, WHITEMAG has been able to provide fundamental insight into the intimate relations between hBN and borophene when synthesized together, into doping mechanism of boron atoms in 2D materials and into relevant molecular processes confined into two dimensions. The results have been reported in prestigious scientific journals, and are expected to inform and enhance publications in diverse fields in the coming years. On the other hand, novel synthesis methods of borophene developed during the action are now in the process of being patented, and are expected to have a direct impact into the growing industry around 2D materials. The main objectives of the WHITEMAG project consist on tailoring the properties of hBN and borophene by (i) creating nanoarchitectures that combine their complementary properties, (ii) developing innovative growth processes, (iii) heteroatom doping or (iv) incorporation of small molecules. The underlying idea is to exploit their properties so that they can become functional materials valuable for a manifold of applications in fields as diverse as nano-electronics, memory storage, gas sensing or catalysis.

Цел на проекта

2D magnetic materials have attracted enormous interest over the last years because of their potential towards miniaturization of novel low-power and memory storage technologies. Isostructural and isoelectronic to graphene, an atomically-thin layer of hexagonal boron nitride (hBN) is electrically insulating, and one of the most prominent 2D materials because of its superior mechanical, thermal and especially chemical properties. Inducing magnetic properties (together with reducing the size of the bandgap) will allow the realization of full potential of hBN nanostructures in functional applications. In this line, the efforts reported to date lack characterization and control of the sample’s properties at the atomic level, which is crucial to achieve a comprehensive understanding of the physical phenomena driving the emergence of magnetic properties.WHITEMAG aims to create routes for controlled magnetic functionalization of hBN in order to induce and exploit emerging electronic and magnetic properties at the atomic scale. hBN will be precisely modified by exploring novel defect engineering methods to introduce substitutional magnetic atoms, and subsequently by designing hybrid nanoarchitectures that combine hBN with magnetic organic molecules. The structural, electronic and magnetic properties of these systems will be studied by STM/STS, XPS/ARPES, nc-AFM and XMCD, giving a complete picture of the phenomena occurring at the atomistic level. The synthesis and characterization experiments will be addressed based on a surface science approach, involving controlled dosing of molecular and atomic species on well-defined surfaces under ultra-high vacuum (UHV) conditions. If successful, the outcomes of this work will push forward the microscopic understanding of magnetic phenomena in low-dimensional systems, and will open new promising perspectives for the implementation of hBN-based nanostructures in future spintronics and molecular electronics applications.
