Electrical Tuning of Terahertz Plasmonic Crystal Phases
P. Sai, V. V. Korotyeyev, M. Dub +9
We present an extensive study of resonant two-dimensional (2D) plasmon excitations in grating-gated quantum well heterostructures, which enable an electrical control of periodic ch…
Two-dimensional spatial coherence of excitons in semicrystalline polymeric semiconductors: The effect of molecular weight
Francis Paquin, Hajime Yamagata, Nicholas J. Hestand +8
The electronic properties of macromolecular semiconductor thin films depend profoundly on their solid-state microstructure, which in turn is governed, among other things, by the pr…
Charge separation by photoexcitation in semicrystalline polymeric semiconductors: An intrinsic or extrinsic mechanism?
Francis Paquin, Gianluca Latini, Maciej Sakowicz +5
We probe charge photogeneration and subsequent recombination dynamics in neat regioregular poly(3-hexylthiophene) films over six decades in time by means of time-resolved photolumi…
Field Effect Transistors for Terahertz Detection: Physics and First Imaging Applications
W. Knap, M. Dyakonov, D. Coquillat +11
Resonant frequencies of the two-dimensional plasma in FETs increase with the reduction of the channel dimensions and can reach the THz range for sub-micron gate lengths. Nonlinear…
Terahertz Radiation Detection by Field Effect Transistor in Magnetic Field
S. Boubanga-Tombet, M. Sakowicz, D. Coquillat +6
We report on terahertz radiation detection with InGaAs/InAlAs Field Effect Transistors in quantizing magnetic field. The photovoltaic detection signal is investigated at 4.2 K as a…
In-plane optical anisotropy due to conduction band electron wavefunctions
J. Łusakowski, M. Sakowicz, K. J. Friedland +2
Photoluminescence measurements were carried out on Be -doped GaAs/AlGaAs heterostructure at 1.6 K in magnetic fields () up to 5 T. Luminescence originating…
