Spin relaxation dynamics of radical-pair processes at low magnetic fields
T. H. Tennahewa, S. Hosseinzadeh, S. I. Atwood +4
We report measurements of room-temperature spin-relaxation times and of charge-carrier spins in a -conjugated polymer thin film under bipolar injection and low ($1\m…
Spin-transport in an organic semiconductor without free charge carrier involvement
H. Popli, J. Wang, X. Liu +5
We have experimentally tested the hypothesis of free charge carrier mediated spin-transport in the small molecule organic semiconductor Alq3 at room temperature. A spin current was…
Floquet spin states in OLEDs
S. Jamali, V. V. Mkhitaryan, H. Malissa +11
Weakly spin-orbit coupled electron and hole spins in organic light-emitting diodes (OLEDs) constitute near-perfect two-level systems to explore the interaction of light and matter…
Imaging of bandtail states in silicon heterojunction solar cells
M. Y. Teferi, H. Malissa, A. B. Morales-Vilches +6
Silicon heterojunction (SHJ) solar cells represent a promising technological approach towards higher photovoltaics efficiencies and lower fabrication cost. While the device physics…
Thermal Activation Bottleneck in TADF OLEDs based on m-MTDATA:BPhen
Nikolai Bunzmann, Douglas L. Baird, Hans Malissa +4
Organic light emitting diodes (OLEDs) based on thermally activated delayed fluorescence (TADF) can be highly efficient because of the conversion of non-radiative triplet to radiati…
Spin-Dependent Charge-Carrier Recombination Processes in Tris(8-Hydroxyquinolinato) Aluminum
H. Popli, X. Liu, T. H. Tennahewa +5
We have studied the nature and dynamics of spin-dependent charge carrier recombination in Tris(8-hydroxyquinolinato) aluminum (Alq) films in light emitting diodes at room tempe…
