Solid State Effects on Exciton States and Optical Properties of PPV
Solid State Effects on Exciton States and Optical Properties of PPV
We perform ab initio calculations of optical properties for a typical semiconductor conjugated polymer, poly-para-phenylenevinylene, in both isolated chain and crystalline packing. In order to obtain results for excitonic energies and real-space wave functions we explicitly include electron-hole interaction within the density-matrix formalism. We find that the details of crystalline …
