In the framework of this thesis Ballistic Electron§Emission Microscopy/ Spectroscopy (BEEM/S) was used to§investigate semiconductor heterostructures. Including§organic semiconductors like titanylphthalocyanine§(TiOPc) and hexa-peri hexabenzocoronene (HBC).§Analyzing the BEEM spectra we find that the TiOPc§increases the BEEM threshold voltage compared to§reference Au/GaAs diodes. The energy dependent§electron transmission properties of TiOPc were§investigated too.§Additionally, an approach for the determination of§the attenuation length of TiOPc as a function of§energy has been successfully introduced. Finally, the§Schottky barrier heights of Au/HBC/GaAs§heterostructures were investigated by BEEM. The high§barrier at the HBC-GaAs interface makes this material§a promising interfacial layer for increasing the open§circuit voltage of GaAs Schottky barrier solar cells.
