Implant Isolation of III-V Compound Semiconductor Devices and Structures. Individual devices in an integrated circuit can be electrically isolated from each other by irradiating the materials between them with high energy ions. This creates defects in the semiconductor that trap charge carriers and thereby increase the resistance of the material. However, the effectiveness of this process depends on the material as well as irradiation and post-irradiation processing conditions. This project aim ....Implant Isolation of III-V Compound Semiconductor Devices and Structures. Individual devices in an integrated circuit can be electrically isolated from each other by irradiating the materials between them with high energy ions. This creates defects in the semiconductor that trap charge carriers and thereby increase the resistance of the material. However, the effectiveness of this process depends on the material as well as irradiation and post-irradiation processing conditions. This project aims to develop an implant isolation scheme for a new class of devices developed by Epitactix, an Australian start-up company founded on CSIRO research. This will be achieved by combining the ANU's experience and expertise in ion-irradiation and defect engineering with the device and processing expertise of Epitactix Pty Ltd.Read moreRead less

The optical microscope has enabled us to see micro-objects, leading to revolutionary discoveries in medicine and natural sciences. However, the smallest object resolved by a microscope is limited by the wavelength of light. To see nanoscale objects smaller than the wavelength, a new tool for nano-imaging is needed. This project will establish a nanoscale optical microscopy facility that will reveal the topology and true colours of the nano-objects. Such information, achieved through spectroscopic analysis of the light emitted or scattered at the nanoscale, will uncover some of the most fundamental aspects of the nanoworld, leading to cutting-edge scientific discoveries and important industrial applications in photonics and solar energy.Read moreRead less
