Graphene field-effect transistors as room-temperature terahertz detectors.

The unique optoelectronic properties of graphene make it an ideal platform for a variety of photonic applications, including fast photodetectors, transparent electrodes in displays and photovoltaic modules, optical modulators, plasmonic devices, microcavities, and ultra-fast lasers. Owing to its high carrier mobility, gapless spectrum and frequency-independent absorption, graphene is a very pro...

Strained-Si modulation doped field effect transistors as detectors of terahertz and sub-terahertz radiation

Strained-Si modulation doped field effect transistors have been studied as detectors of 0.2 THz and 1.6 THz electromagnetic radiation at room temperature. The difference in the gate voltage dependences for 0.2 THz and 1.6 THz radiation and spatial pattern of the transistor response to focused 1.6 THz radiation confirms that the mechanism of detection is linked to the excitations of the two-dime...

Graphene-Based Periodic Gate Field Effect Transistor Structures for Terahertz Applications

We report on theoretical investigation of graphene based Field Effect Transistor (FET) structures for resonant absorption of terahertz (THz) radiation by the plasmons excited in the high sheet concentration and high carrier mobility active layers. Metallic grating gates with varying periods were used to couple the THz radiation into the plasmons in the active region of the devices. Such grating...
