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 ...

Selective Functionalization of Graphene Peripheries by using Bipolar Electrochemistry

Klaus Kern, Kannan Balasubramanian

We present a contactless strategy based on bipolar electrochemistry for the local chemical modification of monolayer graphene sheets supported on a substrate. Specifically, peripheral graphene regions are directly modified by copper nanoparticles, the char ...

Rippling ultrafast dynamics of suspended 2D monolayers, graphene

Nicola Marzari, Giovanni Maria Vanacore, Andrea Cepellotti

Here, using ultrafast electron crystallography (UEC), we report the observation of rippling dynamics in suspended monolayer graphene, the prototypical and most-studied 2D material. The high scattering cross-section for electron/matter interaction, the atom ...

Hydrogen on silicene: like or unlike graphene?

Michele Pizzochero

Hydrogenation of free-standing silicene, the two-dimensional allotrope of silicon, is investigated in detail using first-principles methods and compared with the adsorption of H atoms on graphene. Similarly to graphene, chemisorption of a single H atom on ...

Graphene Based Mechanical Resonators Fabricated via Direct Dry Transfer

Luis Guillermo Villanueva Torrijo, Tom Larsen, Marco Di Gisi

We present here the fabrication of large suspended sheets of graphene for mechanical resonators. The diameter of the circular resonators varies from 1.2 μm to 26.5 μm resulting in diameter-to-thickness aspect ratios as large as 74000. The membranes were fa ...

High Responsivity, Large-Area Graphene/MoS2 flexible photodetectors

Andras Kis, Dumitru Dumcenco, Kolyo Marinov, Domenico De Fazio

We present flexible photodetectors (PDs) for visible wavelengths fabricated by stacking centimeter-scale chemical vapor deposited (CVD) single layer graphene (SLG) and single layer CVD MoS2, both wet transferred onto a flexible polyethylene terephthalate s ...

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 ...

Tuning the isoelectric point of graphene by electrochemical functionalization

Klaus Kern, Kannan Balasubramanian

The ability to control the charge-potential landscape at solid-liquid interfaces is pivotal to engineer novel devices for applications in sensing, catalysis and energy conversion. The isoelectric point (pI)/point of zero charge (pzc) of graphene plays a ke ...
