Research Interests

The Ciszek group desires to understand the fundamental chemical reactivity at the surface of optoelectronically relevant substrates. Modern electronics, especially in lighting applications, have transitioned from inorganic materials to organic. Yet despite the fact that the metal-on-organic contact is crucial to device performance, no chemistry has been developed to optimize the interface. Our group develops reactions to form “monolayers” to alleviate flaws such as poor adhesion and injection barriers that exist in top-contact organic semiconductor devices.

Specifically our group studies the reactions at the surface of organic molecular crystals with vapor dosed adsorbates. From a fundamental standpoint, these reactions are fascinating as geometric considerations (based off molecular orientation in the crystal) appear to be the primary determinant of reactivity and isomer selectivity. Electronic effects appear muted at best. We have been developing composite mechanisms which examine how factors such as the intercalation pathways for adsorbates, the highly anisotropic nature of reaction loci, the relatively weak intermolecular forces within the molecular crystal, and the material’s low surface energies impact reactivity. Fundamental studies are then applied to generate altered surfaces which are then tested for improved interactions with metal top contacts.

At its heart, the group is a blend of surface science, organic chemistry, materials science, and device engineering. Our primary focus is on the surface science, where most of the ground breaking science occurs. Through a combination of MALDI, XPS, PMIRRAS, UV-vis, AFM, x-ray crystallography, and SEM we tease out the chemical changes within a surface for improved device behavior.
