In June 2014, Philip Hofmann was awarded a Sapere Aude Topforkser grant from the Danish Council for Independent Research (DFF). This page reports on the progress of the project.
The experimental isolation of graphene, a single layer of carbon atoms, has shown that truly two-dimensional (2D) materials can exist, contrary to previous predictions. Meanwhile, it has been shown that small flakes of 2D MoS2 or TaS2 can also be isolated from their three-dimensional (3D) parent materials and that the materials’ 2D and 3D versions behave very differently. In this project we will use an alternative approach to grow 2D materials directly on a surface in ultra-high vacuum. This will give rise to higher quality, larger areas and the freedom to design entirely new materials. This type of synthesis will also allow studies by powerful and complementary techniques such as angle-resolved photoemission spectroscopy, scanning tunnelling microscopy and nano-scale transport. We will determine in what way and why the 2D solids are different from their 3D counterparts and how we can influence their properties.
