Journal ArticleDOI
Large magnetoresistance in nonmagnetic π -conjugated semiconductor thin film devices
Omer Mermer,G. Veeraraghavan,T.L. Francis,Y. Sheng,D. T. Nguyen,Markus Wohlgenannt,Anna Köhler,Mohammed K. Al-Suti,Muhammad S. Khan +8 more
TL;DR: In this paper, the authors performed a comprehensive magnetoresistance study on a set of organic semiconductor sandwich devices made from different conjugated polymers and small molecules, including a range of materials that show greatly different chemical structure, mobility, and spin-orbit coupling strength.
Journal ArticleDOI
Large magnetoresistance at room temperature in semiconducting polymer sandwich devices
TL;DR: In this paper, a large room temperature magnetoresistance (MR) effect in polyfluorene sandwich devices in weak magnetic fields was found and the effect is related to the hole current in the devices.
Journal ArticleDOI
Hyperfine interaction and magnetoresistance in organic semiconductors
Y. Sheng,Tho Duc Nguyen,G. Veeraraghavan,Omer Mermer,Markus Wohlgenannt,Song Qiu,Ullrich Scherf +6 more
TL;DR: In this article, the authors explore the possibility that hyperfine interaction causes the recently discovered organic magnetoresistance (OMAR) effect and deduce a simple fitting formula from the hyperfine Hamiltonian that relates the saturation field of the OMAR traces to hyperfine coupling constant.
Journal ArticleDOI
Humidity sensing properties of ZnO nanoparticles synthesized by sol–gel process
TL;DR: In this paper, the relative sensitivity of the ZnO nanoparticles-based humidity sensor was determined by electrical resistance measurements, and the dynamic Langmuir adsorption model was used to determine the kinetic parameters such as adaption and desorption rates under relative humidity between 45% and 88%.
Journal ArticleDOI
Large magnetoresistance at room-temperature in small-molecular-weight organic semiconductor sandwich devices
TL;DR: In this paper, a large, room temperature magnetoresistance (MR) effect in tris-(8-hydroxyquinoline) aluminum sandwich devices was studied and the effect reached almost 10% at fields of 10mT at room temperature.
