The topological nature of large area Sb₂Te₃ and Bi₂Te₃ thin films grown by MOCVD on Si(111), is validated by combining magnetotransport and ARPES studies. You can find all the details in our latest paper "Magnetotransport and ARPES studies of the topological insulators Sb₂Te₃ and Bi₂Te₃ grown by MOCVD on large-area Si substrates" by Lorenzo Locatelli and coauthors, now available at Scientific Reports (Nature Publishing group). 

The work is conducted within the SKYTOP EU project (FETPROACT 2018-01, no. 824123). Contact: Roberto Mantovan
