Optoelectronic Materials Overview

Principles

Definition

Optoelectronic materials is a research field and academic concept focused on the study of substances possessing properties that enable the interaction, conversion, or modulation between electromagnetic radiation (light) and electrical energy. This encompasses the investigation of their fundamental physical principles, synthesis, characterization, and application in devices that detect, generate, or control light using electrical signals, highlighting their critical role in modern technology.

Quantum Confinement and Doping era

David A. B. Miller [1] is a leading figure in this era, with association to University of California, Berkeley [3] and University of Oxford [4]. Miller's key contributions in this era include Room-temperature excitonic nonlinear-optical effects in semiconductor quantum-well structures [7], and Large room-temperature optical nonlinearity in GaAs/Ga1−xAlxAs multiple quantum well structures [8], which advanced quantum confinement-enabled nonlinear optics and practical infrared optoelectronics. D. S. Chemla [2] is a prominent figure with ties to Stanford University [5] and Université Paris-Sud [6]. Chemla's contributions in this era center on the same papers Room-temperature excitonic nonlinear-optical effects in semiconductor quantum-well structures [7] and Large room-temperature optical nonlinearity in GaAs/Ga1−xAlxAs multiple quantum well structures [8], demonstrating room-temperature nonlinear optical effects in quantum-well systems and large nonlinearities in MQWs, which highlighted the role of quantum confinement in enabling infrared sources and detectors.

Interface and Confinement Engineering era

Stephen R. Forrest [1] is a pioneer whose work at Stanford University [3] and Northwestern University [4] in this era helped define optoelectronic materials at interfaces. His key contributions, including the demonstration of nearly 100% internal phosphorescence efficiency in an organic light-emitting device [7], very high-efficiency green organic light-emitting devices based on electrophosphorescence [8], and white organic light-emitting devices for solid-state lighting [9], advanced interface engineering and exciton management essential to the era. Mark E. Thompson [2] was active at MIT [5] and the University of California, Los Angeles [6] during this era. His contributions center on the relationship between electroluminescence and current transport in organic heterojunction light-emitting devices [10], and on achieving high-performance electrophosphorescent devices [8] and nearly 100% phosphorescence efficiency in an organic light-emitting device [7], underscoring how injection, charge transport and exciton confinement shaped energy conversion and lighting technologies in this period.

Perovskite and 2D Convergence era

Henry J. Snaith [1] is a leading figure in perovskite optoelectronics, with stints at Massachusetts Institute of Technology [3] and Ulsan National Institute of Science and Technology [4] during this era. His key contributions include advancing mixed-cation lead mixed-halide perovskite absorbers for tandem solar cells [7] and developing perovskite crystals for tunable white light emission [8], which were important for enabling high-efficiency tandems and versatile emission control in convergent optoelectronic platforms. Giles E. Eperon [2] has been active at University of Washington [5] and Clarendon College [6] during this era. He contributed to the same two papers on mixed-cation lead mixed-halide perovskite absorbers for tandem solar cells [7] and perovskite crystals for tunable white light emission [8], advancing composition-tunable bandgaps and spectral engineering that underpin interface-driven convergence of perovskites with 2D platforms in this era.
