Abstract
A double quantum well (QW) subject to in-plane magnetic fields B-paral lel to has the dispersion curves of its two QWs shifted in k-space. Wh en the QWs are strongly coupled, an anticrossing and partial energy ga p occur, yielding a turnable multi-component Fermi surface. We report measurements of the resultant features in the conductance, the capacit ive density of states and giant deviations in the cyclotron effective masses.
