Quantized escape and formation of edge channels at high Landau levels
A. D. Chepelianskii, J. Laidet, I. Farrer +3
We present nonlocal resistance measurements in an ultra high mobility two dimensional electron gas. Our experiments show that even at weak magnetic fields classical guiding along e…
Colossal non-saturating linear magnetoresistance in two-dimensional electron systems at a GaAs/AlGaAs heterointerface
M. A. Aamir, Srijit Goswami, Matthias Baenninger +5
Engineering devices with a large electrical response to magnetic field is of fundamental importance for a range of applications such as magnetic field sensing and magnetic read-hea…
Unconventional Metallicity and Giant Thermopower in a Strongly Interacting Two Dimensional Electron System
Vijay Narayan, Srijit Goswami, Michael Pepper +6
We present thermal and electrical transport measurements of low-density (10 m), mesoscopic two-dimensional electron systems (2DESs) in GaAs/AlGaAs heterostructures at…
Longitudinal Computer Generated Holograms for Digital Frequency Control in Electronically Tunable Terahertz Lasers
Subhasish Chakraborty, Owen P. Marshall, Md. Khairuzzaman +2
A transverse computer-generated hologram (CGH) diffracts and provides flexible control of incident light by steering it to any point in the projected image plane - i.e. CGHs are ab…
Transport Through an Electrostatically Defined Quantum Dot Lattice in a Two-Dimensional Electron Gas
Srijit Goswami, M. A. Aamir, Christoph Siegert +4
Quantum dot lattices (QDLs) have the potential to allow for the tailoring of optical, magnetic and electronic properties of a user-defined artificial solid. We use a dual gated dev…
On-chip single photon emission from an integrated semiconductor quantum dot into a photonic crystal waveguide
Andre Schwagmann, Sokratis Kalliakos, Ian Farrer +4
We demonstrate the in-plane emission of highly-polarized single photons from an InAs quantum dot embedded into a photonic crystal waveguide. The spontaneous emission rates are Purc…
