Optical characterization of deep level defects in n-type AlInGaP for development of solid-state photomultiplier analogs
Andrew M. Armstrong, Evan M. Anderson, Lisa N. Caravello +6
Characterizing intrinsic defects is an important step in evaluating materials for new optoelectronic device applications. For photomultipliers, suppressing dark currents is critica…
Sensing Few Electrons Floating on Helium with High-Electron-Mobility Transistors
Mayer M. Feldman, Gordian Fuchs, Tiffany Liu +4
We report on low-frequency measurements of few electrons floating on superfluid helium using a bespoke cryogenic cascode amplifier circuit built with off-the-shelf GaAs High-Electr…
Transport Measurements of Surface Electrons in 200 nm Deep Helium-Filled Microchannels Above Amorphous Metallic Electrodes
A. T. Asfaw, E. I. Kleinbaum, M. D. Henry +2
We report transport measurements of electrons on helium in a microchannel device where the channels are 200 nm deep and 3 m wide. The channels are fabricated above amorphous met…
Coherent phenomena in terahertz 2D plasmonic structures: strong coupling, plasmonic crystals, and induced transparency by coupling of localized modes
Gregory C. Dyer, Gregory R. Aizin, S. James Allen +4
The device applications of plasmonic systems such as graphene and two dimensional electron gases (2DEGs) in III-V heterostructures include terahertz detectors, mixers, oscillators…
Interferometric Measurement of Far Infrared Plasmons via Resonant Homodyne Mixing
Gregory C. Dyer, Gregory R. Aizin, S. James Allen +4
We present an electrically tunable terahertz two dimensional plasmonic interferometer with an integrated detection element that down converts the terahertz fields to a DC signal. T…
Induced transparency by coupling of Tamm and defect states in tunable terahertz plasmonic crystals
Gregory C. Dyer, Gregory R. Aizin, S. James Allen +4
Photonic crystals and metamaterials have emerged as two classes of tailorable materials that enable precise control of light. Plasmonic crystals, which can be thought of as photoni…
