Norman Hascoe Distinguished Lecture Series
Spin Physics in Organic Semiconductors
Department of Physics
University of Utah
In this talk I will review the spin physics included in the 'hot' subject of organic light emitting diodes (OLED), as well as the status of the relatively young field of Organic Spintronics. Following a brief review of organic semiconductors and OLEDs, I will summarize the necessary ingredients needed for Organic Spintronics, including spin aligned carrier injection, spin aligned carrier current, and spin detection. The difference between regular Electronics and Spintronics will be emphasized. Next, I will discuss the exciting properties of La1/3Sr2/3MnO3, a ferromagnet (FM) with 100% spin injecting capability, and its importance in operating organic spin valves. Examples will be given of two terminal organic spin devices that include: (i) devices with two FM electrodes for use as spin-valves, (ii) devices with one FM electrode for use as FM detector, and (iii) devices with no FM electrode for use as magnetometer.
