Silicon nanowires have been grown with gallium as catalyst by plasma enhanced chemical vapor deposition. The morphology and crystalline structure has been studied by electron microscopy and Raman spectroscopy as a function of growth temperature and catalys ...
Ferroelectric copolymers of polyvinylidene fluoride and trifluoroethylene are attractive gate materials because of a rather high remanent polarization, low dielectric permittivity, and easy integration on semiconductors due to the low processing temperatur ...
Organic semiconductors are promising materials for future electronic and electroluminescence applications. A detailed understanding of organic layers and nano-sized crystals down to single molecules can address fundamental questions of contacting organic s ...
Understanding the growth mechanism in molecular organic thin films is fundamental to their applications in organic electronics. We present an extensive study of the growth mechanism of pentacene thin films on silicon dioxide (SiO2) using atomic ...
The performance and charge transport characteristics of pentacene transistors with oxide gates such as SiO2 and Al2O3 have been recently shown to largely depend on the density of residual carriers due to electron acceptor defects at the oxide surface. The ...
The goal of this thesis is to contribute to the understanding of charge transport in organic field-effect transistors (OFETs) made of pentacene. Organic thin-film transistors (OTFTs) with active layers thicknesses of 5, 10, 20, and 100 nm were fabricated i ...
High aspect ratio silicon wire arrays with excellent pattern fidelity over wafer-scale area were grown by chemical vapor deposition at moderate temperature, using a gas mixture of silane and hydrogen chloride. An innovative two-step process was developed f ...
We report the observation of a characteristic incubation time in the growth of silicon nanowires using the vapor-liquid-solid growth mechanism. This incubation time manifests itself during the growth process as a characteristic time delay in the range of s ...
This work aims at a better understanding of transport mechanisms which take place in organic semiconductors such as pentacene. More accurately, we believe that the electronic polarization plays a leading part, which we try to identify in the particular cas ...
