Modulation characteristics of uncooled graphene photodetectors

چکیده
We analyze the modulation characteristics of uncooled terahertz (THz) and infrared (IR) detectors using variation density effective temperature two-dimensional electron-hole plasma in uniform graphene layers (GLs) perforated (PGLs) due to absorption THz IR radiation. The performance photodetectors (both GL-photoresistor PGL-based barrier photodiodes) are compared. Their also compared with GL reverse-biased photodiodes. obtained results allow evaluate ultimate frequencies these can be used for their optimization.

All-Graphene Photodetectors
We investigate the optoelectronic properties of novel graphene/FeCl3-intercalated few-layer graphene (FeCl3-FLG, dubbed graphexeter) heterostructures using photovoltage spectroscopy. We observe a prominent photovoltage signal generated at the graphene/FeCl3-FLG and graphene/Au interfaces, whereas the photovoltage at the FeCl3-FLG/Au interface is negligible. The sign of the photovoltage changes ...
متن کاملIntrinsic Response Time of Graphene Photodetectors
Graphene-based photodetectors are promising new devices for high-speed optoelectronic applications. However, despite recent efforts it is not clear what determines the ultimate speed limit of these devices. Here, we present measurements of the intrinsic response time of metal-graphene-metal photodetectors with monolayer graphene using an optical correlation technique with ultrashort laser pulse...
متن کاملIncreased responsivity of suspended graphene photodetectors.
The responsivity of graphene photodetectors depends critically on the elevated temperature of the electronic subsystem upon photoexcitation. We investigate the role of the substrate in providing cooling pathways for photoexcited carriers under ambient conditions by partially suspending few-layer graphene over a trench. Through photocurrent microscopy, we observe p-n junctions near the supported...

Graphene exhibits electrical and optical properties promising for future applications in ultra-fast photonics[1]. High carrier mobility and Fermi velocity[2, 3] combined with its constant absorption over the visible wavelength range to the near-infrared[4] potentially allow its application for photodetection over a broad wavelength spectrum, operating at high frequencies. However, absorption be...

We report on the integration of large area CVD grown single- and bilayer graphene transparent conductive electrodes (TCEs) on amorphous silicon multispectral photodetectors. The broadband transmission of graphene results in 440% enhancement of the detectors' spectral response in the ultraviolet (UV) region at λ = 320 nm compared to reference devices with conventional aluminum doped zinc oxide (...
