Optoelectronic Technology Laboratory (OeTL)
The Optoelectronic Technology Laboratory (OeTL) was founded in July 2019, led by Prof. Donal Bradley and Prof. Paul Stavrinou. OeTL is focused on the development of novel semiconducting optoelectronic materials and devices and their application. In addition to the material development, the research spans the requisite studies into photophysical processes that underpin device operation and, from the molecular level, examines both micro- and nano-scale processes to develop high-performance electrical components that include light-emitting diodes, emitter and amplifier components, solar cells and detectors, etc. While a natural extension of activities currently underway at Oxford University, the OeTL is building capacity towards cost-effective scale-up manufacturing for near-term commercialization.
OeTL has established ~1400m2 laboratory and office areas. A world class research platform includes four laboratories: Advanced Material Development laboratory, Printed Electronics Laboratory (1000 class Cleanroom), Multifunctional Device Fabrication Laboratory, and Optoelectronic and Photonic Characterization Laboratory. High standard equipment meets the design and synthesis of new semiconductor materials, advanced micro- and nano- scale manufacturing techniques, fabrication and characterization of photonic and optoelectronic devices. OeTL has currently established an international team including 8 researchers.
Design and synthesis of new functional materials
Compared with traditional inorganic counterparts, novel semiconductor materials, such as organic/polymeric, quantum dots, hybrid and perovskite materials have extensive advantages. These include widely tunable spectral characteristics, their processability, open form factor and lower manufacturing costs. Flexibility is the key. While initial design may target specific optoelectronic properties, the desired application space along with environmental and commercial aspects also emerge.
Advanced manufacturing technologies
OeTL laboratories are equipped with a suite of multifunctional device fabrication and characterization technologies. Capabilities include a high vacuum multisource cluster tool containing electron beam evaporation and thermal deposition, multi-chamber gloveboxes, and several printer/coater setups including slot-die, ink-jet and spray coater. These versatile platforms provide precise nano-scale preparation of multilayer structures, accurate inspection and control of microstructure and the ability to scale to large-area devices. All valuable for translating fundamental research to pilot-scale verification.
Novel photonic and optoelectronic devices and applications
The design of devices based upon highly resonant, microcavity or subwavelength photonic structures provides our research framework into thin amorphous film semiconducting devices. The key to this is the ability to evaluate accurately, assess and determine stimulated emission processes from a range of materials, including polymer, colloidal quantum dots and perovskites. Efficient light-emitting or detecting devices show great promise over a broad range of industrial and commercial sectors. The Internet of Things (IoT) is increasing demanding compact devices with flexible form in visible light communications, flexible/wearable devices, optical interconnection and the biomedical sector.
