 | Vardeny, Zeev Valentine | Spectroscopic study of spin-dependent exciton formation rates in ∏-conjugated semiconductors: comparison with electroluminescence techniques | It has been found in recent measurements that the singlet-to-triplet exciton ratio in organic light-emitting diodes (OLEDs) is larger than expected from spin degeneracy, and that singlet excitons form at a larger rate than triplets. We employed the technique of optically detected magnetic resonance... | Spin-dependent exciton formation; pi-conjugated polymers | 2004-12 |

 | Vardeny, Zeev Valentine | Spin and magnetic field effects in organic semiconductor devices | The authors describe three spin and magnetic field effects in organic semiconductor devices: First, injection, transport and detection of spin-polarised carriers using an organic semiconductor as the spacer layer in a spin-valve structure, yielding low-temperature giant magnetoresistance effects as... | Spin effects; Magnetic field effects; MR; OLED; Organic light-emitting diode; Spin-polarised carriers; Spin-dependent exciton formation; Electroluminescent efficiency; pi-conjugated organic semicondutors; OSEC | 2005 |
