  • We analyze the effect of weak localization (WL) and weak antilocalization (WAL) in the electronic transport through HgTe/CdTe quantum wells. We show that for increasing Fermi energy, the magnetoconductance of a diffusive system with inverted band ordering features a transition from WL to WAL and back, if spin?orbit interactions from bulk and structure inversion asymmetries can be neglected. This, and an additional splitting in the magnetoconductance profile, is a signature of the Berry phase… CONTINUE READING
