Terahertz Antenna Impedance Matched to a Graphene Photodetector
François Joint, Kunyi Zhang, Jayaprakash Poojali +9
Developing low-power, high-sensitivity photodetectors for the terahertz (THz) band that operate at room temperature is an important challenge in optoelectronics. In this study, we…
Effect of defect-induced cooling on graphene hot-electron bolometers
Abdel El Fatimy, Peize Han, Nicholas Quirk +9
At high phonon temperature, defect-mediated electron-phonon collisions (supercollisions) in graphene allow for larger energy transfer and faster cooling of hot electrons than the n…
Tunable Ultrafast Thermal Relaxation in Graphene Measured by Continuous-Wave Photomixing
M. Mehdi Jadidi, Ryan J. Suess, Cheng Tan +9
Hot electron effects in graphene are significant because of graphene's small electronic heat capacity and weak electron-phonon coupling, yet the dynamics and cooling mechanisms of…
Sensitive Room-Temperature Terahertz Detection via Photothermoelectric Effect in Graphene
Xinghan Cai, Andrei B. Sushkov, Ryan J. Suess +10
Terahertz (THz) radiation has uses from security to medicine; however, sensitive room-temperature detection of THz is notoriously difficult. The hot-electron photothermoelectric ef…
Photo-thermal response in dual-gated bilayer graphene
M. -H. Kim, J. Yan, R. J. Suess +3
The photovoltaic and bolometric photoresponse in gapped bilayer graphene was investigated by optical and transport measurements. A pulse coincidence technique at 1.5 um was used to…
