When: Tuesday, March 18, 2014 4:40 pm - 5:30 pm Where: Physics Building Conference Room (204B) When: Thursday, March 6, 2014 4:00 pm - 5:00 pm Where: Physics Auditorium (Rm 202) The spin-polarized organic light emitting diode (spin-OLED) has been long sought device within the field of Organic Spintronics. We designed, fabricated and studied a spin-OLED with ferromagnetic (FM) electrodes that acts as a bipolar organic spin valve (OSV), based on deuterated derivative of poly(phenylene-vinylene) with small hyperfine interaction [1]. In the double-injection limit the device shows ~1% spin-valve magneto-electroluminescence (MEL) response that follows the FM electrode coercive fields, which originates from the bipolar spin-polarized space charge limited current [2]. Our findings provide a pathway for organic displays controlled by external magnetic fields. Here is the outline of my talk. First, the background of magneto-resistance in OLEDs and OSVs are reviewed. Next, I present some previous attempts to achieve spin-OLEDs. Finally, I show our success on demonstrating spin-LEDs. If the time permits, I will go over the current advances toward Organic Spintronics in our laboratory.
