Tiivistelmä

Metal mining is essential for the increasing demands of technological society. For some precious metals, the needs are unsustainable—maybe even on a human timescale. Yet, for high-end technologies, the use of precious metals could be dramatically reduced. Such reduction would be possible through technologies using atomically thin, two-dimensional (2D) elemental metals (2DEMs). 2DEMs are sizable, single-atom-thick patches of elemental metals stabilized and suspended inside the pores of 2D template materials. However, although the interfaces between 2DEMs and the covalent templates enable the suspension, they are known poorly. Therefore, this computational project aims to design interfaces that maximize the stability of 2DEM patches. This aim is achievable through the following four objectives: 1) Characterize and categorize edges and edge deformations in isolated 2DEMs; 2) Construct a database of interfaces and select a representative set for further study; 3) Resolve the electronic structure trends in the study set of interfaces, and 4) Disclose the origins of dynamic stability in the study set of interfaces. Achieving these objectives help improve 2DEM stabilities, increase their sizes, and make them out of new elements. These improvements drive technologies that use the unique properties of 2DEMs for magnetic, electronic, sensing, and catalytic applications and make the mining of precious metals more sustainable.
