Plasmonic enhancement of aligned semiconducting graphene nanoribbons

Autor: Pfeiffer, M., Senkovskiy, B. V., Haberer, D., Fischer, F. R., Yang, F., Meerholz, K., Ando, Y., Grüneis, A., Lindfors, K.

We couple photoluminescent semiconducting 7-atom wide armchair edge graphene nanoribbons to plasmonic nanoantenna arrays and demonstrate an enhancement of the photoluminescence and Raman scattering intensity of the nanoribbons by more than one order

Effect of hydrogen adsorption on the quasiparticle spectra of graphene

Autor: Farjam, M., Haberer, D., Grüneis, A.

Publikováno v: Phys. Rev. B 83, 193411 (2011)

We use the non-interacting tight-binding model to study the effect of isolated hydrogen adsorbates on the quasiparticle spectra of single-layer graphene. Using the Green's function approach, we obtain analytic expressions for the local density of sta

Report

Quasi-freestanding and single-atom thick layer of hexagonal boron nitride as a substrate for graphene synthesis

Autor: Usachov, D., Haberer, D., Grüneis, A., Sachdev, H., Preobrajenski, A. B., Adamchuk, V. K., Laubschat, C., Vyalikh, D. V.

We demonstrate that freeing a single-atom thick layer of hexagonal boron nitride (hbn) from tight chemical bonding to a Ni(111) thin film grown on a W(110) substrate can be achieved by intercalation of Au atoms into the interface. This process has be
