This chapter discusses the properties of charge-transfer excitons (CTEs) at interfaces and in donor-acceptor superlattices. In particular, collective properties of CTEs at donor-acceptor interface are considered. The possibility of the dielectric-conductor phase transition (cold photoconductivity) at high pumping and the photo-voltaic effect in asymmetrical donor-acceptor superlattices are demonstrated. The resonant as well as off-resonant contributions of CTEs to χ3 optical nonlinearity are also considered.
Keywords: dielectric-conductor phase transition, cold photoconductivity
