Hyperfine interaction and magnetoresistance in organic semiconductors
Y. Sheng, D. T. Nguyen, G. Veeraraghavan +3
We explore the possibility that hyperfine interaction causes the recently discovered organic magnetoresistance (OMAR) effect. Our study employs both experiment and theoretical mode…
Large magnetoresistance at room-temperature in small molecular weight organic semiconductor sandwich devices
Ö. Mermer, G. Veeraraghavan, T. L. Francis +1
We present an extensive study of a large, room temperature negative magnetoresistance (MR) effect in tris-(8-hydroxyquinoline) aluminum sandwich devices in weak magnetic fields. Th…
Weak localization and antilocalization in semiconducting polymer sandwich devices
Ö. Mermer, M. Wohlgenannt, G. Veeraraghavan +1
We have performed magnetoresistance measurements on polyfluorene sandwich devices in weak magnetic fields as a function of applied voltage, device temperature (10K to 300K), film t…
