Objective: Develop and characterize OLEDs based on spin-aligned carrier injection of which electro-luminescence (EL) is controlled by magnetic field.
Approach: Use ferromagnetic cathode and anode that work as bipolar spin- valve injecting both electrons and holes into a deuterated π-conjugated polymer.
Utah MRSEC sponsored 10 undergrads to work with faculty and graduate student mentors in their labs for a 9-week research program. Research opportunities for Utah MRSEC REU students are of an interdisciplinary focus on topics such as plasmonic metamaterials, and spin effects in organic LEDs & solar cells.
Mucus clearance is the primary defense mechanism that protects airways from inhaled infectious and toxic agents. In the current Gel-on-Liquid mucus clearance model mucus gel is propelled on top of a “watery” periciliary layer surrounding the cilia. However, this model fails to explain the formation of distinct mucus layer in health or
Founded by physical chemists like Flory and brought into the mainstream of theoretical physics by visionaries like de Gennes, over the last eighty years polymer physics has grown into a mature, rich, and exciting discipline.
Assembling microscopic particles into macroscopic structures can open new pathways for producing complex materials that cannot be produced by lithographic methods. Although several methods for assembling colloidal particles exist, including controlled drying, ionic interactions, and dipolar interactions, a general pathway for
In July, 2012, the UW-MRSEC hosted graduate students from the University of Puerto Rico Mayaguez. While in Madison, Wisconsin the students performed their Science on Wheels (Ciencias en Ruedas) show at the Wisconsin Institutes for Discovery on the UW-Madison campus.
Manipulating the topology of iso-frequency surface provides a new approach for control of light-matter interaction. This is demonstrated using anisotropic metamaterials consisting of metal-dielectric layers.
Metals have many disadvantages as components of optical metamaterials. Semiconductor-based materials overcome these problems. We build a high performance, all-semiconductor-based metamaterial by replacing metal with heavily-doped zinc oxide and demonstrate negative refraction in this near-infrared metamaterial. This demonstration
LCMRC researchers have developed a method for manipulating particles by light without touching them by using liquid crystals as a light-controlled host fluid.
