Journal ArticleDOI
Plasmon induced thermoelectric effect in graphene
Viktoryia Shautsova,Viktoryia Shautsova,Themistoklis P. H. Sidiropoulos,Xiaofei Xiao,Nicholas A. Güsken,Nicola C. G. Black,Nicola C. G. Black,A. M. Gilbertson,Vincenzo Giannini,Vincenzo Giannini,Stefan A. Maier,Stefan A. Maier,Lesley F. Cohen,Rupert F. Oulton +13 more
TL;DR: The authors leverage strongly localised plasmonic heating of graphene carriers to detect a second photothermoelectric effect occurring across a homogeneous channel in the presence of an electronic temperature gradient.
Journal ArticleDOI
Plasmon-Induced Optical Anisotropy in Hybrid Graphene–Metal Nanoparticle Systems
A. M. Gilbertson,Yan Francescato,Tyler Roschuk,Viktoryia Shautsova,Yiguo Chen,Yiguo Chen,Themistoklis P. H. Sidiropoulos,Minghui Hong,Vincenzo Giannini,Stefan A. Maier,Lesley F. Cohen,Rupert F. Oulton +11 more
TL;DR: It is shown that plasmon-induced hot carrier generation in the graphene is dominated by direct photoexcitation with minimal contribution from charge transfer from the gold, and the strong near-field interaction manifests as an unexpected and long-lived extrinsic optical anisotropy.
Journal ArticleDOI
Hexagonal Boron Nitride assisted transfer and encapsulation of large area CVD graphene.
Viktoryia Shautsova,A. M. Gilbertson,Nicola C. G. Black,Nicola C. G. Black,Stefan A. Maier,Lesley F. Cohen +5 more
TL;DR: A CVD hexagonal boron nitride (hBN-) assisted transfer method that enables a polymer-impurity free transfer process and subsequent top encapsulation of large-area CVD-grown graphene, thereby facilitating the preparation of van der Waals heterostructures with controlled doping is reported.
Journal ArticleDOI
Probing the dielectric response of graphene via dual-band plasmonic nanoresonators
Ye Xiao,Yan Francescato,Vincenzo Giannini,Mohsen Rahmani,Tyler Roschuk,A. M. Gilbertson,Yannick Sonnefraud,Cecilia Mattevi,Minghui Hong,Lesley F. Cohen,Stefan A. Maier +10 more
TL;DR: By using finite element modelling to best reproduce experimental results the dielectric response of the graphene film can be determined and the potential of such structures for chemical sensing applications is discussed.
Journal ArticleDOI
Dimensional crossover and weak localization in a 90 nm n-GaAs thin film
TL;DR: Evidence of a crossover from two-dimensional to three-dimensional behavior with respect to both coherent transport (WL) and e-e interactions is observed in the temperature dependence of the zero-field conductivity and tau(varphi), respectively.
