Bio/Description
Stephen C. Macaleer '63 Professor in Engineering and Applied Science
Vice Dean, School of Engineering and Applied Science
Associated Faculty in the Princeton Institute of Materials (PRISM)
My research programs center on the electronic, chemical, structural and electrical properties of materials relevant to thin-film electronic devices. My interests span a range of semiconductor materials (elemental and compounds), but my current work focuses specifically on organic molecular and polymer semiconductors, dielectrics developed for applications in organic and molecular electronics, and the hot new class of optoelectronic materials called hybrid metal halide perovskites (MHP). Our group is particularly interested in engineering materials and interfaces that improve the performance of devices, with application to organic light-emitting diodes (OLEDs), field effect transistors (OFETs), organic photovoltaic cells (OPVs), MHP-based solar cells and light emitting diodes, and other thin-film devices applicable to large-area, flexible electronics.
?
On the organic scene, the quasi-infinite possibilities for chemical synthesis of new organic molecular compounds, combined with the unmatched ease of fabrication of organic semiconductor films by vacuum evaporation, liquid processing or printing on a variety of substrates, give organic semiconductors key advantages over other semiconductor materials, and open tremendous opportunities for innovation in device structures. Our research spans fundamental issues of electron-hole interaction in molecular semiconductors; chemistry and electronic structure of metal-organic and organic-organic heterojunctions; physics, implementation and impact of chemical (n- and p-) doping to control conductivity and carrier injection.
?
On the metal halide perovskite side, our work contributes to a better understanding of surface and interface properties of these fascinating materials. We are investigating their interfaces with metal oxides and organics (small molecules and polymers alike), which are all central to device performance.
?
Our group is involved in extensive collaborations with synthetic chemists, theoreticians, and device physicists in the US, Asia, and Europe, in academia, national laboratories, and industry. Our approach involves a variety of spectroscopic techniques for determining electronic structures, charge carrier transport measurements, morphological and structural tools, and device fabrication.
