Submillimeter-wave cornea phantom sensing over an extended depth of field with an axicon-generated Bessel beam
Mariangela Baggio, Aleksi Tamminen, Joel Lamberg +9
The feasibility of a 220 - 330 GHz zero order axicon generated Bessel beam for corneal water content was explored. Simulation and experimental data from the 25-degree cone angle hy…
THz Superradiance from a GaAs: ErAs Quantum Dot Array at Room Temperature
W-D. Zhang, E. R. Brown, A. Mingardi +3
We report experimental evidence that an ErAs quantum-dot array in a GaAs matrix under 1550 nm pulsed excitation produces cooperative spontaneous emission-Dicke superradiance-in the…
The Critical Effect of Hydration on the Resonant Signatures of THz Biospectroscopy
E. R. Brown, W-D. Zhang
Here we present an original study of the effect of hydration on Terahertz absorption signatures in biomolecular (lactose monohydrate and biotin) and bioparticles( Bacillus thuringi…
Noise Measurements of High-Speed, Light-Emitting GaN Resonant-Tunneling Diodes
E. R. Brown, W-D. Zhang, T. A. Growden +4
We report here the first RF noise measurements on two designs of n-doped GaN/AlN double-barrier resonant tunneling diodes (RTDs), each having a room-temperature negative differenti…
Strong Band-Edge Light Emission from InGaAs RTDs: Evidence for the Universal Nature of Resonant- and Zener- Co-Tunneling
E. R. Brown, W-D. Zhang, T. A. Growden +2
We report strong light emission from a room-temperature n-type unipolar-doped In0.53Ga0.47As/AlAs double-barrier resonant-tunneling diode (DBRTD) precisely at the In0.53Ga0.47As ba…
Kondo-Resonance Mediated Metal-Insulator Transition in GaAs Embedded with Erbium Arsenide Quantum Dots
W-D. Zhang, E. R. Brown, A. D. Feldman +2
We report anomalous critical transport behavior in a GaAs structure containing a dense array of ErAs quantum dots. The structure displays a voltage (electric field)-controlled insu…
