A research team led by Prof. Daniel LAU, Chair Professor of Nanomaterials and Head of Department of Applied Physics of PolyU and Associate Director of Photonics Research Institute (PRI) discovered that bilayers of molybdenum disulphide and tungsten disulphide produced at the nanometre scale retain their intrinsic ferroelectric property so that electrical polarisation can be reversed by simply applying an external electric current. The manufacturing of this new class of nano-scale ferroelectrics can be reproduced at large scales with low cost, low energy demand and faithful reproducibility. The research result promises to advance the frontier of modern electronics and attract keen interest among electronics manufacturers.
This research was a collaboration project involving researchers from the Renmin University of China, University of Cambridge and Nanjing University. The study has been published on Science.
