Photoconductive receivers at 1030 nm for high average power pulsed THz detection
Tim Vogel, Samira Mansourzadeh, Uttam Nandi +3
In the last few years, many advances have been made in the demonstration of high-average power pulsed THz sources; however, little effort has been made to study compatible sensitiv…
Wavelength conversion through plasmon-coupled surface states
Deniz Turan, Ping Keng Lu, Nezih T. Yardimci +7
Surface states generally degrade semiconductor device performance by raising the charge injection barrier height, introducing localized trap states, inducing surface leakage curren…
Terahertz response of patterned epitaxial graphene
C. Sorger, S. Preu, J. Schmidt +5
We study the interaction between polarized terahertz (THz) radiation and micro-structured large-area graphene in transmission geometry. In order to efficiently couple the radiation…
Arrayed Continuous-wave THz Photomixers
S. T. Bauerschmidt, S. Malzer, G. H. Döhler +3
We present both chip-scale and free space coherent arrays of continuous-wave THz photomixers. By altering the relative phases of the exciting laser signals, the relative THz phase…
Ultra-fast transistor-based detectors for precise timing of near infrared and THz signals
S. Preu, M. Mittendorff, S. Winnerl +3
A whole class of two-color experiments involves intense, short Terahertz radiation pulses. A fast detector that is sensitive and able to resolve both near-infrared and Terahertz pu…
Self-assembled ErSb nanostructures of tunable shape and orientation: growth and plasmonic properties
Hong Lu, Daniel G. Ouellette, Sascha Preu +5
Self-assembled, semimetallic ErSb single crystal nanostructures, grown by molecular beam epitaxy, are embedded within a semiconductor GaSb matrix. Formation, evolution and orientat…
