چکیده
We investigate the optical response of graphene nanoribbons (GNRs) using broadband nonlinear generation and detection capabilities nanoscale junctions created at LaAlO3/SrTiO3 interface. GNR nanoclusters measured to be as small 1–2 GNRs in size are deposited on LaAlO3 surface with an atomic force microscope tip. Time-resolved probes reveal a strong, gate-tunable second third harmonic response, well strong extinction visible near-infrared light distinct wavelengths, similar previous reports graphene.

Tunable doping of graphene nanoribbon arrays by chemical functionalization.
We demonstrate the controlled tuning of the electronic band structure of large-arrays of graphene nanoribbons (GNRs) by chemical functionalization. The GNR arrays are synthesized by substrate-controlled metal-assisted etching of graphene in H2 at high temperature, and functionalized with different molecules. From Raman spectroscopy and carrier transport measurements, we found that 4-nitrobenzen...
متن کاملGate-tunable photoemission from graphene transistors.
In this Letter, we report gate-tunable X-ray photoelectron emission from back-gated graphene transistors. The back-gated transistor geometry allows us to study photoemission from graphene layer and the dielectric substrate at various gate voltages. Application of gate voltage electrostatically dopes graphene and shifts the binding energy of photoelectrons in various ways depending on the origin...
متن کاملGate-tunable coherent perfect absorption of terahertz radiation in graphene
Perfect absorption of radiation in a graphene sheet may play a pivotal role in the realization of technologically relevant optoelectronic devices. In particular, perfect absorption of radiation in the terahertz (THz) spectral range would tremendously boost the utility of graphene in this difficult range of photon energies, which still lacks cheap and robust devices operating at room temperature...
متن کاملGate-variable optical transitions in graphene.
Two-dimensional graphene monolayers and bilayers exhibit fascinating electrical transport behaviors. Using infrared spectroscopy, we find that they also have strong interband transitions and that their optical transitions can be substantially modified through electrical gating, much like electrical transport in field-effect transistors. This gate dependence of interband transitions adds a valua...
متن کاملTHz-circuits driven by photo-thermoelectric, gate-tunable graphene-junctions
For future on-chip communication schemes, it is essential to integrate nanoscale materials with an ultrafast optoelectronic functionality into high-frequency circuits. The atomically thin graphene has been widely demonstrated to be suitable for photovoltaic and optoelectronic devices because of its broadband optical absorption and its high electron mobility. Moreover, the ultrafast relaxation o...
