Functional thin films

Functional inorganic thin films

Pressure sensors are used in a range of areas such as aerospace, industrial processing, and power generation. They are typically based on a thin diaphragm with a piezoresistive thin film on top, which can provide electrical read-out upon deflection of the diaphragm by a pressure gradient. However, the properties of most piezoresistive thin films are not stable at high temperatures making such pressure sensors unsuitable for high-temperature operation.

At NanoSYD, we have recently launched an activity on development of advanced materials for high-temperature strain gauges. The materials are deposited by a reactive sputtering process, which can enable the composition and the morphology of the deposited films to be varied over a wide range. The thin films are studied by a range of experimental techniques incl. ellipsometry, energy-dispersive X-ray spectroscopy, atomic force microscopy, and electrical and electromechanical measurements.

Functional organic thin films

Organic semiconductors from small molecules have a vast application potential as the active ingredient in electric and optoelectronic devices. Their self-organization into quasi one-dimensional crystallites adds a peculiar attribute, making, optical components straightforward to accomplish. Functionalization of the molecules allows the formation of entities with specifically designed properties. Since their macroscopic properties and applicability are dictated by nanoscopic morphology, the focus of the research is on understanding the in-situ growth and (opto-) electronic properties of organic nanofibers and nanoparticles, i.e.

  • epitaxy, morphology, and polarization optics of thin organic films
  • thermal and temporal stability of organic nanoentities
  • electrostatic properties and conductivity of organic thin films on the nanoscale
