Our proposal consists in transposing the concept of a TI to crystalline organic materials, which will meet the future technological requirements for low-cost and eco-friendly materials, besides being flexible. The project targets unambiguous signatures of an organic topological insulator (OTI), and proof-of-principle meso- and nano-devices for electronic and thermal transport. The project also targets original insights into the unique quantum spin Hall state, by means of high resolution spin-sensitive imaging.


The chosen strategy is strongly multidisciplinary, and covers a broad range from materials science, to surface physics, electronic device physics, and computational chemistry and physics. The consortium gathers experts from three leading academic research laboratories, bringing complementary approaches and backgrounds. Institut FEMTO-ST will lead the chemistry side of the work plan. Institut Néel will be in charge of combined structural, vibrational, and electronic transport studies, and will also conduct the theoretical work. IPCMS will perform low temperature microscopy and spin-polarized spectroscopy. 



This project is funded by the Agence Nationale de la recherche, challenge #3 (défi 3) of the 2015 action plan of the ANR, devoted to stimulating industrial renewal.
