Nebraska MRSEC Professor/Student Pairs Program

Jeffrey Shield (Nebraska MRSEC)

The Nebraska MRSEC Professor/Student Pairs Program brings in professor/student pairs from non-research intensive four-year institutions to conduct research with Nebraska MRSEC scientists.  The goal is to provide a research experience which benefits both the participants and the MRSEC projects.  For the professor, this program provides an opportunity to conduct new research, access to facilities typically unavailable at their home institution, and make strong and lasting connections with MRSEC researchers.  For the student, this program provides an opportunity to conduct world-class research

Organic Molecular Layers for Efficient Charge Injection

High conductivity and efficient charge injection into organic layers could lead to the design of more efficient organic solar cells and molecular electronics, especially light emitting diodes. Most organic materials are however insulators and only few exhibit high conducting properties. Nebraska MRSEC researchers in collaboration with their colleagues at University of Puerto Rico have discovered that zwitterion molecules of the p-benzoquinonemonoimine type are different from being a standard insulator.

Enhanced Ferroelectric Stability by Interface Engineering

A. Gruverman and E. Y. Tsymbal (Nebraska MRSEC); C.-B. Eom (University of Wisconsin); X. Pan (University of Michigan)

Ferroelectric materials are characterized by a spontaneous polarization that can be switched by external electric field. This property is important for various technological applications such ferroelectric random access memories. However, when ferroelectric film thickness is reduced down to a nanoscale the ferroelectric polarization may become unstable due to strong depolarization fields and interface effects.
