J. Yoon et al., Parallel magnetic field induced transition in transport in the dilute two-dimensional hole system in GaAs, PHYS REV L, 84(19), 2000, pp. 4421-4424
A magnetic field applied parallel to the two-dimensional hole system in the
GaAs/AlGaAs heterostructure, which is metallic in the absence of an extern
al magnetic field, can drive the system into insulating at a finite field t
hrough a well-defined transition. The value of resistivity at the transitio
n is found to depend strongly on density.
