Thin films for smart sensors and beyond Stimuli-responsive materials are characterized by dynamic switching of their properties depending on external stimuli (e.g. light, pH, temperature, humidity). In particular, hydrogels change their size and shape when exposed to aqueous environments. Functional and responsive surf ... more |

Optimize Surface Polymorph Growth with Optimal Control Techniques Organic molecules adsorbed on inorganic surfaces can form a huge number of different structures on the surface so called polymorphs. These polymorphs have different properties. Which polymorph is formed depends mostly on external parameters like temperature and pressure. To achi ... more |

Electro-optical Characterization of Point Defects in Si, SiC and GaN Devices Charge carriers flowing through the channel of a MOSFET can get trapped in the bulk or at the SiC/SiO$_2$ interface and affect the device performance. These trap levels have their origin in the different crystal structures of SiC and SiO$_2$ which lead to a lattice mismatch. If t ... more |

Transfer learning on organic/inorganic interfaces for different substrates Performing structure search of organic molecules on metallic surfaces requires finding the structure with the smallest energy. Using conventional density functional codes this proves to be a time consuming task since the number of possible configurations is large and individual c ... more |

Deposition of Multi-Stimuli-Responsive Sensors and Study of their Response Range to Temperature Thin hydrogel double layers (100 nm each) were deposited under varying conditions on plain Silicon, as well as nano-patterned substrates using initiated chemical vapor deposition. The resulting structure is a sensor responsive to multiple stimuli which are temperature, humidity a ... more |

Polymorph screening on surfaces applied to anthraquinone Polymorphism describes the existence of crystals with different structures but the same molecular composition. In order to find new polymorphs a method called polymorph screening is well established in pharmaceutics. For this work the procedure of polymorph screening was adapted ... more |

Development of a Climate chamber for In-Situ μ-CT measurements of Paper samples in a humid environment Ongoing research in the μ-CT Lab at TU Graz tries to find out where water can impinge in a paper
sample. This research led to the follow up question of how paper behaves under the influence of
humidity. To realize measurements of paper under the influence of humidity the f ... more |

Microfabrication building blocks towards high frequency resonators for 5G RF filters applications Increasing usage of mobile wireless traffic, and thus an increasing amount of Radio Frequency (RF) filters has led to a growing demand of surface acoustic wave (SAW) and bulk acoustic wave (BAW) devices. Recently, hybrid quasi-SAW/BAW resonators were reported, that show high pote ... more |

Evaluating nanoscale contact and adhesion using FRET microscopy Several intermolecular mechanisms are responsible for adhesion: hydrogen bonding, van der Waals forces and electrostatic interaction. Among these mechanisms hydrogen bonding and van der Waals attraction only work if molecular contact -- i.e. a distance between surfaces below a fe ... more |

Early life failure mechanisms detection in power MOSFETs by means of thermal burn-in One of the key challenges for manufacturers is the reliability of the ICs when built into the customer’s application. Therefore, the semiconductor devices integrated in these ICs, need to work exactly as supposed to. A more prominent effect in this context is the so-called bath ... more |
