High bandwidth-efficiency solar-blind AlGaN Schottky photodiodes with low dark current

Al0.38Ga0.62N/GaN heterojunction solar-blind Schottky photodetectors with low dark current, high responsivity, and fast pulse response were demonstrated. A five-step microwave compatible fabrication process was utilized to fabricate the devices. The solarblind detectors displayed extremely low dark current values: 30lm diameter devices exhibited leakage current below 3fA under reverse bias up t...

Gaseous Dark Matter Detectors

Dark Matter detectors with directional sensitivity have the potential of yielding an unambiguous positive observation of WIMPs as well as discriminating between galactic Dark Matter halo models. In this article, we introduce the motivation for directional detectors, discuss the experimental techniques that make directional detection possible, and review the status of the experimental effort in ...

Dark matter detectors as dark photon helioscopes.

Light new particles with masses below 10 keV, often considered as a plausible extension of the standard model, will be emitted from the solar interior and can be detected on Earth with a variety of experimental tools. Here, we analyze the new "dark" vector state V, a massive vector boson mixed with the photon via an angle κ, that in the limit of the small mass mV has its emission spectrum stron...

Low dark current InAs/GaSb type-II superlattice infrared photodetectors with resonant tunnelling filters

InAs/GaSb type-II strained-layer superlattice (SLS) photovoltaic infrared (IR) detectors are currently of great interest for midand long-wave IR detection. A novel technique of reducing detector dark current by inserting resonant tunnelling barriers into a conventional InAs/GaSb SLS is investigated. The GaSb/InAs/GaSb resonant tunnelling double barrier heterostructure was designed to be periodi...

Performance of Very Low Dark Current SWIR PIN Arrays

In photon counting imaging applications a focal plane array consisting of a detector and readout integrated circuit (ROIC) array must both be low noise. At room temperature, InGaAs PIN detector arrays are most suitable because the required signal bandwidth is fairly modest and the first stage input amplifiers on the ROIC can be very low noise. However, in many applications relatively long integ...
