Research

Research in our group focuses on materials and manufacturing techniques for high‑performance organic electronic devices.

One area of interest is the advancement of organic transistors for large‑area electronic applications on unconventional substrates.

For example, we are developing materials and methods to reduce the operating voltage and power consumption of organic thin‑film transistors and circuits.
To improve the manufacturability of organic transistors we are exploring high‑resolution printing techniques, such as microcontact printing and inkjet printing.
We are investigating the mechanisms responsible for the undesired degradation of organic semiconductor films and develop both p‑channel and n‑channel organic transistors with large carrier mobility and improved stability.
To better understand the behavior of organic transistors at the nano‑scale we are designing and manufacturing organic transistors with channel lengths down to 100 nm.

In addition to organic transistors we are also interested in a variety of organic and hybrid nanostructures and nano‑scale devices that take advantage the of unique properties of certain functional organic materials, such as molecular self‑assembled monolayers.

For example, we are employing thin molecular gate dielectrics to improve the performance of nano‑scale electronic devices, such as field‑effect transistors and integrated circuits based on inorganic semiconductor nanowires and single‑walled carbon nanotubes.
We are creating and investigating organic/inorganic radial superlattices that are obtained through a combination of inorganic molecular beam epitaxy and organic molecular self-assembly.
