Non-Epitaxial Layered Intergrowths of 2D Materials by Atomic Layer Deposition (A06)

• Subject Area: Solid State and Surface Chemistry, Material Synthesis ; Experimental Condensed Matter Physics ; Synthesis and Properties of Functional Materials
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 417590517

The project will prepare a material class of stacked topological insulators (TIs) and non-vdW 2DMs, called ferecrystals, by atomic layer deposition (ALD). As a basis, thin films of TIs (< 10 nm) have been selected due to their 2D nature and superior electronic properties, like high mobility of the charge carriers due to highly conductive crystal interfaces. We will start a new avenue by the growth of ferecrystals based on TIs and conductive organic interlayers. For both ferecrystal systems, we will develop measurement platforms for the cross-plane transport of thermoelectric properties.
