Magnetic-field-driven destruction of quantum Hall states in a double quantum well
The magnetotransport of double-quantum-well structures reveals a high-magnetic-field
regime in which quantum Hall states at odd-integer ν are missing, where ν is the number of …

Observation of a linearly dispersing collective mode in a quantum Hall ferromagnet
Double-layer two-dimensional electron systems can exhibit a fascinating collective phase
believed to display both quantum ferromagnetism and excitonic superfluidity. This unusual …

Probing a two-dimensional Fermi surface by tunneling
Equilibrium tunneling between parallel two-dimensional electron systems is measured as a
function of in-plane magnetic field and sheet density. For equal two-dimensional densities …

Field emission in emerging two-dimensional and topological materials: A perspective
Since the first field emission model or the well-known Fowler–Nordheim (FN) law was
formulated about a century ago (in 1928), it remains an active topic to discover different …
