Journal ArticleDOI
Evidence for a new dissipationless effect in 2D electronic transport.
TL;DR: These findings are likely indicative of a collective ground state previously unknown for 2DES, characterized by an exponentially vanishing low-temperature diagonal resistance and a classical Hall resistance.
Journal ArticleDOI
Resonantly enhanced tunneling in a double layer quantum hall ferromagnet.
TL;DR: The tunneling conductance between two parallel 2D electron systems has been measured in a regime of strong interlayer Coulomb correlations and a huge resonant enhancement replaces the strongly suppressed equilibrium tunneling characteristic of weakly coupled layers.
Journal ArticleDOI
Controlling the sign of quantum interference by tunnelling from quantum wells
TL;DR: In this paper, the authors report the control of interference in optical absorption by quantum mechanical tunnelling, which can provide a way to make semiconductor lasers operate without population inversion.
Journal ArticleDOI
Inhomogeneous spatial distribution of reverse bias leakage in GaN Schottky diodes

TL;DR: In this paper, the reverse bias leakage current in macroscopic GaN Schottky diodes is found to be insensitive to barrier height, while most of the sample is insulating.
Journal ArticleDOI
Long-range transport in excitonic dark states in coupled quantum wells
TL;DR: Photoluminescence measurements of InGaAs quantum wells are reported and the observation of an effect by which luminescence from excitons appears hundreds of micrometres away from the laser excitation spot is reported.
