Abstract:
In this work, we have engineered Aluminum (Al)-based plasmonic devices with MXene (
Ti3C2Tx) nanosheet to achieve both
high sensitivities as well Figure of Merit (FOM) simultaneously for the wavelength of 1550 nm in the optical communication
band. Since, studying 2D nanomaterials can provide quality collaboration for Ti3C2Tx,
from their functionalization to
application; Black Phosphorus, Graphene, fluorinated Graphene, and MoS2
are undertaken for this purpose. The effect of
such 2D nanomaterials has been studied on both sensitivity and FOM for Ti3C2Tx-
based engineered Al-plasmonic devices
and a decent value of both sensitivity (119°/RIU) and FOM (
340RIU−1) is achieved in the Kretschmann’s configuration. To
demonstrate the bio-sensing application with the proposed plasmonic devices, the detection of protein solution concentration,
based on the change in their refractive indices, is carried out. The proposed Ti3C2Tx-
based Al-plasmonic devices show promising
applications in the optical communication band, employing fluorinated graphene and MoS2
in the near-infrared region.
