  New two diemensional structures nanoribbon including phosphorus and germanium
atoms are introduced for the nanoelectronic applications. Under various bias
voltages, the electronic transport in the systems have been studied within the
noneqilibrium Green's function formalism. The $I-V$ characteristics have been
extracted. DOS and $T(E,V_{bias})$ have been investigated and show that the
charge transport occurs when the bias voltage reaches about 1 \textit{V}. The
calculated MPSH shows that the spatial distribution of orbital levels has been
affected by the electrodes. The studied structures have a bandgap of about 0.7
\textit{eV} which absorbs light in the visible range and thus could be an
interesting contender for solar cells applications.
