Ti substituted nano-crystalline Cu3N thin films

Atomic Transport in Nano-crystalline Thin Films

Ge and B diffusion was studied in nano-crystalline Si, and Pd and Si self-diffusion was studied in nano-crystalline Pd2Si during and after Pd/Si reactive diffusion. These experiments showed that grain boundary (GB) diffusion kinetic is the same in microand nano-GBs, whereas triple junction (TJ) diffusion is several orders of magnitude faster than GB diffusion. In addition, GB segregation and GB...

Spin Exchange Interaction in Substituted Copper Phthalocyanine Crystalline Thin Films

The origins of spin exchange in crystalline thin films of Copper Octabutoxy Phthalocyanine (Cu-OBPc) are investigated using Magnetic Circular Dichroism (MCD) spectroscopy. These studies are made possible by a solution deposition technique which produces highly ordered films with macroscopic grain sizes suitable for optical studies. For temperatures lower than 2 K, the contribution of a specific...

Multifunctional nanostructured Ti-Si-C thin films

In this Thesis, I have investigated multifunctional nanostructured Ti-Si-C thin films synthesized by magnetron sputtering in the substrate-temperature range from room temperature to 900 °C. The studies cover high-temperature growth of Ti3SiC2 and Ti4SiC3, low-temperature growth of Ti-Si-C nanocomposites, and Ti-Si-C-based multilayers, as well as their electrical, mechanical, and thermal-stabili...

Glass transition and crystallization of amorphous Ni–Ti–Zr thin films by combinatorial nano-calorimetry

Homoepitaxy of Crystalline Rubrene Thin Films.

The smooth surface of crystalline rubrene films formed through an abrupt heating process provides a valuable platform to study organic homoepitaxy. By varying growth rate and substrate temperature, we are able to manipulate the onset of a transition from layer-by-layer to island growth modes, while the crystalline thin films maintain a remarkably smooth surface (less than 2.3 nm root-mean-squar...
