abstract = {pH sensors, with high sensitivity, durability, and low
cost, are considered to be essential tools in several
applications such as laboratory experiments, water quality,
agriculture, and healthcare. Because of their unique
properties, carbon allotropes have attracted a lot of
attention during the last decade to be utilized in several
applications, in which pH sensing is one of them. In this
work, a hybrid film of graphene nanoplatelets (GPs) and gold
nanoparticles (GNPs), where the GNPs are embedded in the GP
layer, was used as an active layer in an electronic pH senor
based on a capacitive metal oxide semiconductor.
Capacitance–voltage measurements have shown a change in
the flatband voltage with changing the applied pH. The
sensitivity of the GP–Au nanoparticle hybrid (GAH) film
has been enhanced by a factor of $26.7\%$ compared to the GP
film. We refer the higher sensitivity to the increase in the
surface potential of the GAH, which became n-doped by the Au
nanoparticles, resulting in a change of the Fermi level of
the GP layer. This sensor is easy to fabricate and
demonstrates sensitivity that is higher than previously
reported electronic pH sensitivities using different
configurations.},
