  In this work we study thermoelectric properties of graphene nanoribbons with
side-attached organic molecules. By adopting a single-band tight binding
Hamiltonian and the Green's function formalism, we calculated the transmission
and Seebeck coefficients for different hybrid systems. The corresponding
thermopower profiles exhibit a series of sharp peaks at the eigenenergies of
the isolated molecule. We study the effects of the temperature on the
thermoelectric response, and we consider random configurations of molecule
distributions, in different disorder regimes. The main characteristics of the
thermopower are not destroyed under temperature and disorder, indicating the
robustness of the system as a proposed molecular thermo-sensor device.
