Nonlinear THz spectroscopy and simulation of gated graphene

Juan Ramon Mosig, Michele Tamagnone

We studied the nonlinear optical properties of single layer graphene using high terahertz (THz) fields. With the use of a back gate and cooling down the sample to cryogenic temperatures we are able to spectrally probe the nonlinear THz properties of intrin ...

Transfer of graphene on polymeric foil

Marsha Mary Parmar, Guilhem Edouard Baptiste Noiraud

Since its creation in 2004 [1], graphene has become an important subject in the scientific community. From the Scotch tape method, many techniques have been developed to fabricate and manipulate graphene flakes. This project aims to transfer graphene flake ...

Some Like It Flat: Decoupled h-BN Monolayer Substrates for Aligned Graphene Growth

Silvan Dino Marcos Roth

On the path to functional graphene electronics, suitable templates for chemical vapor deposition (CVD) growth of high -mobility graphene are of great interest. Among various substrates, hexagonal boron nitride (h-BN) has established itself as one of the mo ...

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 ...

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 ...

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 for Nanoelectronic Applications

Pankaj Sharma

During the past decade, graphene --- a monolayer of carbon atoms --- has attracted enormous interest for its use in nanoelectronic device applications. The absence of bandgap, however, has stalled its use both in logic (inability to turn off) and radio fre ...

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 ...
