Abstract
Heterostructures of crystalline organic and inorganic semiconductors based on the aromatic compound PTCDA (3, 4, 9, 10-perylenetetracarboxylic dianhydride, C24O6H8) are investigated. Crystal growth by organic molecular beam deposition (OMBD) on different substrates and optical characterization are discussed. Homogeneous crystalline films are attained at low growth rates and substrate temperatures from T=77 K to T=350 K. With regard to applications in optoelectronic integrated circuits (OEICs) waveguide structures, photodetectors and a concept for the integration of these two devices are presented. Due to the low process temperatures optoelectronic devices can be prepared on already processed III-V and silicon wafers.Keywords
