Owing to the unique thickness dependent physical and chemical properties, two-
dimensional (2D) layered nanomaterials have received tremendous attention and shown …

Graphene materials have been widely explored for the fabrication of gas sensors because of
their atom-thick two-dimensional conjugated structures, high conductivity and large specific …

We use resonance Raman and optical reflection contrast methods to study charge transfer in
1–10 layer (1L–10L) thick graphene samples on which NO2 has adsorbed. Electrons …

Correlation between conductance and surface work function (SWF) changes caused by
molecular adsorption on epitaxial graphene on both faces of 6 H-SiC has been investigated …

The electronic properties of monolayer graphene grown epitaxially on SiC (0001) are known
to be highly sensitive to the presence of NO 2 molecules. The presence of small areas of …

We show SiC substrate phonon-induced surface plasmon polariton (SPP) formation in
epitaxial graphene grown on 4H–SiC, in SiC's restrahlen band (8–10 μm). By fitting …

Epitaxial graphene grown on SiC (0001) showed significant changes in electrical resistance
upon exposure to polar protic and polar aprotic vapors in the ambient atmosphere. The …

We investigate molecular adsorption doping by electron withdrawing NO2 and electron
donating NH3 on epitaxial graphene. Amperometric measurements show conductance …

Laser induced ablation studies have been carried out on formation of amorphous carbon
and graphene on SiC thin films with their detailed characterization studies. Pulse laser …

Optical computing has been proposed for high performance applications owing to light's
high frequency and noise tolerance. However, the diffraction limit of light prevents the …
