Dr Xuhua Wang is a Research Fellow (Senior Scientist) in Physics  for a number of years. Besides her academic research, she also has significant industrial experiences with pioneering companies (Opsys Ltd, Cambridge Display Technology Ltd, Exitech Ltd and Molecular Vision Ltd) as a senior scientist in developing organic light emitting diodes (OLEDs) for displays and organic electronic devices integrated with microfluidic chips for bioanlaytical and medical diagnostic applications, lasers for micromachining tools. Her expertise covers a wide range of subjects over many years including high power laser systems, laser photonics, carbon-based materials science and their optoelectronic device physics and engineering including LEDs, transistors, solar cells, photodiodes and sensors with many practical skills (research supervision, instrumentation controlling and optoelectronic system setting up, materials processing and theoretical modelling, organic electronic device physics and fabrications).

Her recent research includes

  • Development of thin film transparent electrodes for flexible plastic electronic applications. It includes vapour phase polymerised poly(3,4 ethylenedioxythiophene) (VPP-PEDOT) and single-walled carbon nanotubes (SWCNTs) and silver nanowires (AgNWs). These electrodes can be used as p-type transparent anodes for polymer light emitting diodes (pLEDs), organic transistors, organic solar cells and other types of electronic devices.
  • Polymer photosensors with two terminals and three terminals, which include photodetectors and phototransistors. The interfacial layer structure within the devices play a crucial role to determine their characteristics. Understanding physics behind provides important information to improve the device performance.
  • Organic electronic devices for bioanalytical and medical applications, in particular, such devices integrated with microfluidic chips to form portable devices employed in field or on site use.
  • Designing a prototype device demo.
