Z. Valy Vardeny plenary: Spin Effects in Organic Optoelectronic Devices
Several important developments in the field of organic spintronics and magnetic field effect in organic optoelectronic devices are surveyed and discussed in the plenary talk, "Spin Effects in Organic Optoelectronic Devices" with Z. Valy Vardeny of University of Utah (USA).
Vardeny notes that his research team has demonstrated spin organic light emitting diodes using two FM injecting electrodes, where the electroluminescence depends on the mutual orientation of the electrode magnetization directions. This development has opened up research studies into organic spin-valves in the space-charge limited current regime.
The team has also demonstrated that spin ½ radical additives to donor-acceptor (D-A) blends improve the power conversion efficiency via resonant spin-spin interaction between the radicals and charge-transfer excitons at the D-A interfaces.
Z. Valy Vardeny is Distinguished Professor of Physics at the University of Utah. He is a Fellow of the APS, the editor of Nature Communication, and has published more than 500 articles. Vardeny has recieved the 1997 Willard Award, the 2005 Utah Governor's Medal of Science, the 2008 Frank Isakson APS Prize, and the 2009 Rosenblatt Award for Excellence.
