We investigate how charge, excitons, heat, and interfaces govern solution-processed electronic and optoelectronic devices. By connecting fundamental transport physics with device architecture, scalable processing, and data-driven analysis, we develop light-emitting, energy-harvesting, and adaptive electronic systems. AONE Lab engineers quantum-dot light-emitting diodes (QLEDs) across the full device hierarchy, from charge injection and nanoscale interfaces to optical structures and full-color patterning. We combine steady-state and transient electrical and optical measurements with simulation and machine learning to determine how transport layers, QD films, and device architecture govern efficiency, brightness, and operational stability. Our goal is to translate fundamental device physics into robust display technologies across scales, including microdisplay-oriented, top-emission, large-area, flexible, and transparent platforms. Charge injection, transport, balance, recombination, and exciton–charge dynamics under electrical operation. QD/transport-layer interfaces, ZnO- and ZnMgO-based electron-transport layers, degradation pathways, and operational lifetime. Ultra-high-brightness, top-emission, and optical-cavity structures, together with flexible, stretchable, and transparent devices. Full-color QD patterning through photolithography, electrophoretic deposition, and inkjet printing, including analysis of process-induced changes. OLEDs and other organic optoelectronic devices provide complementary systems for investigating charge transport, interfaces, and mechanically compliant architectures. We investigate electronic and thermal transport in solution-processable semiconductors and engineer thin-film thermoelectric systems that convert low-grade or spatially complex
