Retraction of Nature paper puts Majorana research on a new path – Physics World
The interlayer coupling, which has a strong influence on the properties of van der Waals heterostructures, strongly depends on the interlayer distance. Although considerable theoretical interest has been demonstrated, experiments exploiting a variable interlayer coupling on nanocircuits are scarce due to the experimental difficulties. Here, we demonstrate a novel method to tune the interlayer coupling using hydrostatic pressure by incorporating van der Waals heterostructure based nanocircuits in piston-cylinder hydrostatic pressure cells with a dedicated sample holder design. This technique opens the way to conduct transport measurements on nanodevices under pressure using up to 12 contacts without constraints on the sample at fabrication level. WTe2 is a material with rich topological properties: it is a 2D topological insulator as a monolayer and a Weyl-semimetal and higher-order topological insulator in the bulk form.

How do we balance the potential of nanotechnology with the potential hazards from new and often inadequately characterized materials? The rapid expansion of nanotechnology is a powerful scientific and economic force. However, we need to match this progress with careful evaluation of the possible toxicity of nanomaterials and technologies. This process can be made more efficient by searching for fundamental principles that govern biological responses to nanomaterials, rather than assessing the toxicity of specific nanomaterials one at a time.
