Elvira M. C. Fortunato: Green Electronics -- A Technology for a Sustainable Future
A plenary talk from SPIE Optics + Photonics 2016
The evolution from rigid silicon-based electronics to flexible electronics requires the use of new materials with novel functionalities that allow non-conventional, low-cost and environmental friendly processing technologies. Among the alternatives, metal oxide semiconductors have brought to attention as backplane materials for the next generation of flat panel displays. After the huge success and revolution of transparent electronics and with the worldwide interest in displays where metal oxide thin films have proved to be truly semiconductors, display backplanes have already gone commercial in a very short period of time, due to the huge investment of several high profile companies: SHARP, SAMSUNG, LG and BOE. These materials have demonstrated exceptional electronic performance as active semiconductor components and can be tuned for applications where high transparency/electrical conductivity is demanded. The new paradigm of transparent electronics has attracted much interest as a novel technical solution in the field of the next generation of consumer electronics. The ultimate goal of this "see-through" device is to realize an integrated system equipped with ubiquitous functions of information storage, image display and networking, which strongly demands an embeddable transparent array of non-volatile memory.
Elvira Fortunato is full professor in Materials Science Department of Faculty of Science and Technology of New University of Lisbon, a Fellow of the Portuguese Engineering Academy since 2009 and decorated with the grade of Grand Officer of the Order of Prince Henry the Navigator by the President of the Republic in 2010, due to her scientific achievements worldwide. In 2015 she was appointed by the Portuguese President Chairman of the Organizing Committee of the Celebrations of the National Day of Portugal, Camões and the Portuguese Communities. In November 2015 she become Deputy Adviser of the High Level Group of Scientific Advice Mechanism from DG Research & Innovation European Commission. Fortunato pioneered European research on transparent electronics, namely thin-film transistors based on oxide semiconductors, demonstrating that oxide materials can be used as true semiconductors. In 2008, she demonstrated with her colleagues the possibility to make the first paper transistor, starting a new field in the area of paper electronics.
