"Forbidden" transitions between quantum Hall and insulating phases in p-SiGe heterostructures
M. R. Sakr, Maryam Rahimi, S. V. Kravchenko +3
We show that in dilute metallic p-SiGe heterostructures, magnetic field can cause multiple quantum Hall-insulator-quantum Hall transitions. The insulating states are observed betwe…
Interaction effects and the metallic phase in p-SiGe
P. T. Coleridge, A. S. Sachrajda, P. Zawadzki
Magnetoresistance results are presented for p-SiGe samples on the metallic side of the B=0 metal-insulator transition. The results cannot be understood within the framework of stan…
Weak localisation, interaction effects and the metallic phase in p-SiGe
P. T. Coleridge, A. S. Sachrajda, P. Zawadzki
Magnetoresistance results are presented for p-SiGe samples on the metallic side of the B=0 metal-insulator transition. It was possible to separate the weak localisation and Zeeman…
