New fabrication facilities for van-der-Waals heterostructures

Nanostructure fabrication to support FLEET research

FLEET’s research to achieve zero-dissipation electrical current depends on the design of key nanoscale structures.

In 2017, Research theme B leader Lan Wang, and PhD student Cheng Tan, developed a method to build such nanoscale structures, required to achieve zero- dissipation electrical current. These nanostructures, comprising two stacked, 2D semiconductors, are key to FLEET’s Research theme 1 (topological materials) and Research theme 2 (exciton superfluids).

Bound together by van der Waals (vdW) forces, and comprising twin, disparate, atomically-thin layers, such structures are known as van der Waals heterostructures.
