Abstract magnified image Topological insulators provide a gateway to investigate fundamental quantum behaviours of exotic quasi‐particles as well the promise revolutionize modern technology. This is due their unique surface states that are robust against time reversal perturbation and exhibit spin‐momentum locking property. Enhancing state signal in proportion bulk material critical study for future electronics applications. can be achieved by making topological into nanostructures, which have large volume ratios thus maximizing signal. article reviews recent progress made insulator nanostructures including chemical physical synthesis techniques make notable transport experiments, current efforts protect from degradation. Lastly, studies using various methods tune materials properties diverse electronic applications suggested. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
