Magnetoresistance in organic spin valves and spin organic light emitting diodes Rugang Geng Luong, Hoang Mai Timothy Tyler Daugherty Lawrence Hornak Tho Duc Nguyen Magnetoresistance Organic spintronics Spin transport Spin diffusion length Tunneling p. 256-272 In the preceding review paper, Paper I [Journal of Science: Advanced Materials and Devices 1 (2016) 128 e140], we showed the major experimental and theoretical studies on the first organic spintronic subject, namely organic magneto-resistance (OMAR) in organic light emitting diodes (OLEDs). The topic has recently been of renewed interest as a result of a demonstration of the magneto-conductance (MC) that exceeds 1000% at room temperature using a certain type of organic compounds and device operating condition. In this report, we will review two additional organic spintronic devices, namely organic spin valves (OSVs) where only spin polarized holes exist to cause magneto-resistance (MR), and spin organic light emitting diodes (spin-OLEDs) where both spin polarized holes and electrons are injected into the organic emissive layer to form a magneto-electroluminescence (MEL) hysteretic loop. First, we outline the major advances in OSV studies for understanding the underlying physics of the spin transport mechanism in organic semiconductors (OSCs) and the spin injection/detection at the organic/ferro-magnet interface (spinterface). We also highlight some of outstanding challenges in this promising research field. Second, the first successful demonstration of spin-OLEDs is reviewed. We also discuss challenges to achieve the high performance devices. Finally, we suggest an outlook on the future of organic spintronics by using organic single crystals and aligned polymers for the spin transport layer, and a self-assembled monolayer to achieve more controllability for the spinterface 2017-08-23T08:08:26Z 2017-08-23T08:08:26Z 2016 Article 2468-2284 http://repository.vnu.edu.vn/handle/VNU_123/57944 en application/pdf ĐHQGHN |
