High-Entropy Materials and High Throughput Synthesis/Characterization:

High-entropy materials offer versatile properties due to their individual elemental compositions and lattice geometry enabling the design of unique electronic and electrochemical properties. We employ robotic wet chemistry, spin coating, miniaturized droplet cells for impedance spectroscopy, UV/Vis, fast XRD by gallium jet technology and automized electrical probe stations. These methods enable rapid screening of vast compositional spaces and providing valuable insights into structure-property relationships.

Solution processible materials and thin films:

Nanomaterials and complex multicomponent materials exhibit unique properties that are highly desirable for flexible and printed electronics. We investigate the materials from a powder level to their formulation into functional inks and up to the characterization of their film properties such as semiconducting, piezoelectric and mixed ionic-electronic transport properties.

Additive manufacturing with printing technologies:

We use various methods and printing technologies in 2D and 3D such as inkjet printing, superinkjet printing, electrohydrodynamic printing, capillary printing and other scanning probe lithography techniques as well as laser printing. To be able to print fully functional electronic devices we explore the limits of printing resolution and work on novel ink recipes, substrate/ink interaction and combinations with other thin film techniques.

Printed electronic devices and circuits:

We explore novel device concepts and architectures such as electrolyte gated thin film transistors, analog and digital memristors, ferroelectric gated devices, as well as novel circuit topologies such as neuromorphic circuits and hardware security primitives (e.g. physical unclonable functions).

3D Electronics:

Bioelectronics and sensors:

Printing technologies and printable materials offer a great potential for manufacturing bio-hybrid sensors and systems combining conventional electronic and biological materials. We work on bio-functionalized electrodes for improved cell compatibility, electrodes with biomimetic membranes for disease diagnosis, bio-functionalized extended-gate-electrodes or channels in printed field effect transistors and interfaces of electronics with biological components such as cells and organoids.
