Perspectives of HgTe Topological Insulators for Quantum Hall Metrology

Ivan Yahniuk, Sergey S. Krishtopenko, Grzegorz Grabecki +16

We report the studies of high-quality HgTe/(Cd,Hg)Te quantum wells (QWs) with a width close to the critical one $d_c$, corresponding to the topological phase transition and graphen…
