Organic spin-valves: from unipolar to bipolar devices
Literature Information
Z. Valy Vardeny
We review the recent advances in both unipolar and bipolar organic spin valves. We discuss mechanisms that dominate the spin relaxation of injected spin aligned carriers and limit their spin diffusion length. A space charge limited current model with ferromagnetic electrodes is used to describe the bipolar organic spin valve operation. For unipolar spin valves we take into account finite spin diffusion length and obtain a general expression that is valid for devices with thick organic interlayers. For bipolar spin valves where the injected spin aligned electrons and holes selectively form polaron pairs having singlet or triplet spin configurations, we obtain modified expressions for the magneto-resistance and magneto-electroluminescence and show that they are proportional to the difference in singlet–triplet generation rates and the spin injection polarization degree of the ferromagnetic electrodes.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
