Alternative Buffer-Layers for the Growth of SrBi2Ta2O9 on Silicon

In this work we investigate the influence of the use of YSZ and CeO2/YSZ as insulators for Metal- Ferroelectric-Insulator-Semiconductor (MFIS) structures made with SrBi2Ta2O9 (SBT). We show that by using YSZ only the a-axis oriented Pyrochlore phase could be obtained. On the other hand the use of a CeO2/YSZ double-buffer layer gave a c-axis oriented SBT with no amorphous SiO2 inter- diffusion layer. The characteristics of MFIS diodes were greatly improved by the use of the double buffer. Using the same deposition conditions the memory window could be increased from 0.3 V to 0.9 V. From the piezoelectric response, nano-meter scale ferroelectric domains could be clearly identified in SBT thin films.Comment: 5 pages, 9 figures, 13 refernece

Tomorrow's Doctors: Review of The Australian Medical Workforce Advisory Committee (AMWAC)

The aim of this Review, prepared under the auspices of the Australian Health Ministers' Advisory Council, is to 1. Assess AMWAC's performance to date against its original terms of reference and assess to what extent have expectations been achieved? 2. Assess and make relevant recommendations on future national medical workforce planning needs, taking account of the relationship between the medical workforce and other health professionals and support staff, and AHMAC's decision to establish the Australian Health Workforce Advisory Committee (AHWAC); and the relationship between workforce and broader health systems issues. 3. Assess and make relevant recommendations on the suitability of AMWAC - including its structure and methodology - for meeting future medical workforce planning needs, taking account of access to and utilisation of evidence-based data; need for independence and access to broadly sourced advice; international experiences; and current issues, including the changing medical workforce; the implications of the application of the Trade Practices Act 1974 and competition policy; and corporatisation of medical practice. 4. Consider and recommend on appropriate financial commitment by AHMAC to medical workforce planning
