Model the full electroluminescent behaviour of organic light emitting diodes (OLEDs) using OghmaNano’s comprehensive multi-physics engine. From charge injection to light extraction, the simulator captures every key process with physical fidelity.
- Simulate steady-state, transient, and AC operation of OLED devices across 1D, 2D, and 3D structures.
- Include trap-assisted recombination and complex energetic disorder — essential for modeling lifetime and efficiency roll-off.
- Visualise electron and hole density profiles, recombination zones, and quasi-Fermi levels in space and time.
- Use transfer matrix methods (TMM) or ray tracing to calculate angular and spectral emission patterns, including interference effects from electrodes and transport layers.
- Model light emission probabilities from within the device, including position-dependent escape cone and waveguide losses.
- Explore the effects of layer thickness, material properties, and mobility imbalance on overall device performance.
- Fit your experimental I–V–L and EQE data to extract trap densities, recombination constants, and injection barriers.
OghmaNano offers a powerful, flexible simulation environment for OLED researchers and engineers. Whether you're designing a new emitter molecule or analyzing degradation in white OLED stacks, our tools help bridge the gap between experiment and theory.
