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…

Quantum Phase Transitions in the p-SiGe system
P. T. Coleridge, P. Zawadzki, A. Sachrajda +2
The rich variety of phase transitions observed in the strained p-SiGe system are considered and compared. It is shown that the integer quantum Hall effect transitions, the Hall ins…
