Discovery: A class of 2D covalent organic framework made of triphenyl- metal compounds are found to be topological insulators exhibiting robust nontrivial topological edge states.
Approach: Predictive First-principles band structure and band topology calculations.
In our system, a colloidal particle (upper left (a), red) is trapped by optical tweezers (upper left (b)) as a surrounding colloidal suspension flows past. Surprisingly, long range order develops in the particle density (lower left, dark bands are regions with over-representation of particles, sigma is the particle diameter).
Using the expertise in nanoparticle synthesis and assembly built up in IRG 3, a MRSEC team comprised of members of the Jaeger and Talapin groups collaborated with Xiao-Min Lin and Jeffrey Guest at Argonne’s Center for Nanoscale Materials and John Sader from the University of Melbourne to develop the first completely self-assembled nano-mechanical resonator.
Ferroelectrics comprise an important group of materials, which are characterized by a permanent electric polarization. This polarization can be switched which provides a possibility of using ferroelectrics in data storage and memory devices. Typically, polarization is switched by the application of the external electric field. Nebraska MRSEC researchers
The Nebraska MRSEC Professor/Student Pairs Program brings in a professor and a student from non-research intensive four-year institutions to conduct research with Nebraska MRSEC scientists. The goal is to offer a research experience which benefits both the participants and the MRSEC projects.
