Plasmonic Antennas based Gas sensor using Graphene
Plasmonics based sensors have been a prominent area of research. Plasmonics based sensors are widely used in bio sensing and many other applications. The basic mechanism in which these sensors operate is that there are metal nano particles that are separated by a very small distance between them. The dimensions of these nano particles is much smaller than the incident light [1]. For sensing pur...
متن کاملTiO2/Graphene oxide nanocomposite as an ideal NO gas sensor: A density functional theory study
We performed a density functional theory investigation on the structural and electronic properties of pristine and nitrogen-doped TiO2/Graphene oxide nanocomposites as the adsorbents for the removal of toxic NO molecules in the environment. We presented the most stable adsorption configurations and examined the interaction of NO molecule with these doped and undoped nanocomposites. It turns out...

متن کاملSuspended Graphene-Based Gas Sensor with 1-mW Energy Consumption
This paper presents NH3 sensing with ultra-low energy consumption for fast recovery and a graphene sheet based on a suspended microheater. Sensitivity and repeatability are important characteristics of functional gas sensors embedded in mobile devices. Moreover, low energy consumption is an essential requirement in flexible and stretchable mobile electronics due to their small dimension and flu...
متن کاملUltrasensitive NO2 Gas Sensor Based on Epitaxial Graphene
We report about technology of fabrication and optimization of a gas sensor based on epitaxial graphene. Optimized graphene/metal contact configuration exhibited low contact resistance. Complementary annealing of graphene sensor after each gas exposure led to significant improvement in the sensing performance. The response of the annealed sensor to the nitrogen dioxide (NO 2 ) was tenfold higher...
