The Quantized Hall Insulator: A New Insulator in Two-Dimensions
M. Hilke, D. Shahar, S. H. Song +3
Quite generally, an insulator is theoretically defined by a vanishing conductivity tensor at the absolute zero of temperature. In classical insulators, such as band insulators, van…

Symmetry in the insulator - quantum Hall - insulator transitions observed in a Ge/SiGe quantum well
M. Hilke, D. Shahar, S. H. Song +3
We examine the magnetic field driven insulator-quantum Hall-insulator transitions of the two dimensional hole gas in a Ge/SiGe quantum well. We observe direct transitions between l…
