Exciton screening in C${}_{60}$ and PTCDA complexes. TDDFT calculations with GGA and hybrid functionals

N. L. Matsko, Mahmoud A. Salem

Photoabsorption in the low-energy region for C${}_{60}$ and PTCDA molecular complexes is studied within linear response TDDFT. For the PBE, B3LYP and HSE exchange-correlation (xc) fu…
