Nanophotonic and Nanoelectronic Devices from Oxide Semiconductors

Project description


Materials, Equipment and Processes for Production of Nano-Photonic and Nano-Electronic Devices

Self-organisation of nanostructures is an attractive way to fabricate nanodevices. A variety of self organised ZnO nanostructures have been realised recently (nanopillars, nanowires, nanobelts,..) that could have novel applications in optoelectronics, sensors, transducers etc. ZnO is a wide bandgap semiconductor with a record value of exciton binding energy and extremely large oscillator strength, which make it a good candidate for UV nanophotonics at room temperature. Oxides can also be used for gas sensing applications and the large surface area of nanostructures is one of their attractive aspects in this regard. ZnO based devices will find their application in areas such as communication, security environment or biomedical sciences. ZnO based nanodevices can be fabricated on a variety of substrates, including silicon or flexible polymer, which makes them compatible with existing silicon technology and organic electronics and optoelectronics. The objective of this project is to develop and optimise ZnO nanostructures that will give rise to a variety of nanodevices. Among the many potential applications, we have chosen to demonstrate devices in one specific sector, optoelectronics, with a particular emphasis on lighting technology. For this purpose, we will: (1) Grow self-organised ZnO based nanostructures on various substrates, such as sapphire, silicon, as well as polymer substrates, by different techniques, (2) Optimise the control of self-organisation in terms of position, distribution, orientation, size, shape, electrical conductivity, radiative quantum efficiency, (3) Demonstrate ZnO nanodevices comprising: light emitting devices (nano-LEDs), in the UV as well as for white light emitters, ZnO nanolasers operating at room temperature. (4) Optimise fabrication processes in view of achieving compatibility with existing and emerging industrial production techniques.
