Abstract:
In the present thesis thin films of DNA and RNA bases, namely cytosine, thymine, and uracil as well as thin films of hydrogen silsesquioxane (HSQ) have been studied on various substrates using surface science methods.
The main topic of this thesis are geometrical and electronic structures of the DNA and RNA bases, which have been characterized and discussed intensively. Additionally, the interface properties of the three DNA/RNA bases have been investigated. Thymine has been used for mobility studies on the surface.
Thin films of hydrogen silsesquioxane were done concerning the structure on molecular level. Also practical use of the high resolution photoresist (FOx12) in conjunction with the DNA base cytosine as binding molecule for the functionalized resist have been studied.
In this thesis the experimental investigations were performed with photoelectron spectroscopy (XPS, UPS) and Fourier-transform infrared spectroscopy (FTIR – transmission und ATR). Theoretical calculations were performed to support the experimental data.
