Switching mechanisms in nonvolatile resistive memory using high-k dielectrics. Growth in the use of portable electronic devices, such as cameras, phones and MP3 players has resulted in an increased demand for low-power, high-density, non-volatile memory (NVM). One class of such memories aims to use resistance changes in thin dielectric films as a means of storing information. This project aims to develop a better understanding of these devices and to develop new and innovative processes for co ....Switching mechanisms in nonvolatile resistive memory using high-k dielectrics.

One class of such memories aims to use resistance changes in thin dielectric films as a means of storing information. This project aims to develop a better understanding of these devices and to develop new and innovative processes for controlling data storage. The project is based on collaboration between researchers at the ANU and Silanna, an Australian start-up company aiming to develop and commercialise such technology.Read moreRead less

Overcoming performance limitations in multicrystalline silicon solar cells. This project aims to address the major impediments to improved efficiency of multicrystalline silicon solar cells, the most prevalent in industry today. Three key areas have been identified: understanding the fundamental source of carrier recombination in this material, the application of plasma silicon nitride to reducing this recombination, and developing a suitable technique for texturing the front surface of the cell ....Overcoming performance limitations in multicrystalline silicon solar cells. This project aims to address the major impediments to improved efficiency of multicrystalline silicon solar cells, the most prevalent in industry today. Three key areas have been identified: understanding the fundamental source of carrier recombination in this material, the application of plasma silicon nitride to reducing this recombination, and developing a suitable technique for texturing the front surface of the cells. By using novel, advanced techniques to gain a deeper physical understanding of these issues, it will be possible to develop new, cost-effective processes that improve efficiency and are applicable in industry.Read moreRead less
The development of inexpensive negatively charged films to increase the efficiency of commercial solar cells. This project aims to reduce the cost of solar electricity by developing inexpensive, negatively charged dielectric films. When deposited on the surfaces of commercial solar cells, these films will significantly increase cell efficiency, thereby producing more power from a given area.
Reducing health disparities for culturally and linguistically diverse peoples. This project aims to develop a greater understanding of migrants and the factors that predict poor health outcomes related to blood-borne viruses and sexually transmitted infections. The delayed access by migrants to healthcare from culturally and linguistically diverse backgrounds results in late diagnosis, low treatment uptake, and poorer health outcomes, with enhanced risk of infection and increased burden on the h ....Reducing health disparities for culturally and linguistically diverse peoples. This project aims to develop a greater understanding of migrants and the factors that predict poor health outcomes related to blood-borne viruses and sexually transmitted infections. The delayed access by migrants to healthcare from culturally and linguistically diverse backgrounds results in late diagnosis, low treatment uptake, and poorer health outcomes, with enhanced risk of infection and increased burden on the health system. The data collected in this project will assist in developing health services to meet these needs.Read moreRead less
A novel approach to direct nanopatterning of silicon for advanced phase-changed devices. This project will exploit key research developments at ANU in the field of nanotechnology, specifically nanofabrication of entirely new devices. In particular, this work will be exploited by a new Australian high-tech company, WRiota, to produce novel silicon phase change devices.

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

Enhancing the Understanding and Performance of Passivating TiO2 Coatings for Photovoltaic Devices. Titanium dioxide (TiO2) has been widely used as an antireflection coating in the silicon (Si) photovoltaics industry as it exhibits excellent optical properties and low deposition cost. However, recently manufacturers have been turning to alternatives such as hydrogenated silicon nitride coatings that exhibit greatly improved electronic properties, but cost 4 - 10 times more to deposit.

Titanium dioxide (TiO2) has been widely used as an antireflection coating in the silicon (Si) photovoltaics industry as it exhibits excellent optical properties and low deposition cost. However, recently manufacturers have been turning to alternatives such as hydrogenated silicon nitride coatings that exhibit greatly improved electronic properties, but cost 4 - 10 times more to deposit. This project seeks to understand the fundamental limitations behind the poor surface passivation afforded by TiO2 to a Si wafer, and subsequently develop a passivating TiO2 coating that can reduce the cost of electricity generated by Si solar cells.Read moreRead less
