GRAPHENEPHOTODETECTORSHYBRID systemsNANOPARTICLE synthesisHybrid materials in optoelectronic devices can provide synergistic effects that complementarily enhance the properties of each component. Here, flexible high-performance graphene hybrid photodetectors (PDs) are developed by introducing gold nanostars (GNSs) ...
High-speed, high-efficiency photodetectors play an important role in optical communication links that are increasingly being used in data centres to handle higher volumes of data traffic and higher bandwidths, as big data and cloud computing continue to
Also, arginine amino acid was used to modify the surface of graphene oxide nanosheets which the prepared support can improve dispersion and uniform loading of nanoparticles. The prepared nanocomposite was characterized by flame atomic absorption spectroscopy (FAAS), inductively coupled plasma optical ...
dependence of real part of the optical conductivity Reσ xx and Reσ yy are shown in Figs. 2, with two different chem- ical potentials. It is found that the photon absorption starts from ω = 0 and increases with ω for a graphene with µ = 0 (Figs. 2(a) and 2(c)) at lo...

Recently, graphene particles measuring a few nanometers, graphene quantum dots (GQDs), were successfully synthesized; these particles were shown to demonstrate the quantum confinement effect, resulting in tunable electronic and optical properties.18, 19 Interestingly, GQDs are enriched with oxygen function...
Graphene has offered a broad spectral bandwidth potentially up to B500 GHz and fast response time down to B1.5 ps in PD applications3–9, but weak light absorption and low gain have limited key figures of merit such as quantum efficiency (QE), responsivity and noise equivalent power (NEP) ...
