Super-geometric electron focusing on the hexagonal Fermi surface of PdCoO2

Philip Johannes Walter Moll, Maja Deborah Bachmann, Matthias Carsten Putzke

Geometric electron optics may be implemented in solids when electron transport is ballistic on the length scale of a device. Currently, this is realized mainly in 2D materials characterized by circular Fermi surfaces. Here we demonstrate that the nearly pe ...

Modeling Superlattices of Dipolar and Polarizable Semiconducting Nanoparticles

Federico Giberti

We present an analytical model to describe the stability of arbitrary semiconducting nanoparticle (NP) superlattices as a function of the dipole and polarizability of their constituents. We first validate our model by comparison with density functional the ...

Performance metrics and enabling technologies for nanoplasmonic biosensors

Hatice Altug

Nanoplasmonic structures can tightly confine light onto a material's surface to probe biomolecular interactions not easily accessed by other sensing techniques. New and exciting developments in nanofabrication processes, nano-optical trapping, graphene dev ...

2D Material-Metal contact resistance measurement

Tom Larsen

Metal/graphene contact resistance is becoming a major limiting factor in the creation of graphene devices. In this report, we will study and refine the whole process flow towards the creation of graphene devices meant for contact resistance measurements. W ...

Fabrication of 2D Material Based NEMS Resonators

Tom Larsen, An Tran

2D materials such as graphene, MoS2 and phosphorene are promising candidates for resonating mechanical sensors due to excellent tunable electrical/- mechanical properties, low masses, and maximal surface to volume ratios. Mechanical resonators based on sup ...

Intercalation of graphene on SiC(0001) via ion implantation

Klaus Kern

Electronic devices based on graphene technology are catching on rapidly and the ability to engineer graphene properties at the nanoscale is becoming, more than ever, indispensable. Here, we present a procedure of graphene functionalization on SiC(0001) tha ...

A primary battery-on-a-chip using monolayer graphene

Klaus Kern, Kannan Balasubramanian

We present here a bottom-up approach for realizing on-chip on-demand batteries starting out with chemical vapor deposition-grown graphene. Single graphene monolayers contacted by electrode lines on a silicon chip serve as electrodes. The anode and cathode ...

Theoretical Limits on the Efficiency of Reconfigurable and Nonreciprocal Graphene Antennas

Juan Ramon Mosig, Michele Tamagnone

Theoretical upper limits on the radiation efficiency of reconfigurable antennas based on graphene are presented in closed form and discussed. The theory provides useful information for the design of these structures independently of the type and geometry o ...

Graphene

Laurent Syavoch Bernard

We report a full study of graphene synthesis by CVD on Cu surface. Two CVD methods have been developed. The first is a static one, which yields monolayer of graphene at low pressure of methane in 3 minutes at 1000 C. The second one is an equimolar method w ...
