Wide band gap semiconductor single crystals and insulating thin films are emerging as promising alternatives to metallic substrates in surface science, offering a means to prevent the quenching of electronic and optical excitations in surface-bound atoms, molecules, and nanoarchitectures. In this thesis, we explore the potential of GaN and TiO2 single crystals, as well as Cu2N thin films, for these applications. The efficacy of these substrates for on-surface reactions and subsequent electronic spectroscopy analyses is thoroughly examined in the following chapters.
