Brief summary of expertise and significant research achievements:
Dr Ridgway has made significant contributions to the fields of processing
and characterisation of semiconductor materials with technological
relevance in electronic and photonic device fabrication. He pioneered
and developed implant isolation technologies for both Si and compound
semiconductors based on high-energy ion implantation and this processing
method is used today in selected, vertical compound semiconductor devices.
As a result of his research on the production and stability of
implantation-induced disorder, he was elected to the Bohmische Physical
Society.
Dr Ridgway's contributions to the understanding of the recrystallisation of amorphised semiconductors yielded new insights into this important phenomenon. In particular, he was the first to establish the causes of defective recrystallisation in amorphised, compound semiconductors ending years of debate in the international literature. Furthermore, he pioneered the application of synchrotron-radiation-based x-ray techniques to implanted semiconductors, for example, demonstrating a bond-length composition dependence in crystalline and amorphised GexSi1-x alloys and an implant-parameter dependence for the structure of amorphised Ge. He was the first to quantify the separate contributions of the reduction in bond-length and bond-angle distortion to the relaxation enthalpy during structural relaxation in amorphised Ge.
Most recently, graduate students and post-doctoral fellows within the Ridgway group demonstrated structural relaxation of InP is mediated by point-defect annealing and nanocrystals of Ge exhibit subtle structural perturbations relative to bulk material. Such experiments were technically challenging, necessitating innovative processing and analysis methods. The significance of his contributions to both ion-beam and x-ray characterisation were demonstrated by appointment to national/international specialist committees in both disciplines, invited national/international conference presentations and multiple high-quality journal publications.
With others, Dr Ridgway lobbied for the construction of a national synchrotron.
He was subsequently appointed to the National Scientific Advisory
Committee for the Australian Synchrotron and is currently responsible
for the EXAFS beamline. He is a frequent referee for both international
journals and granting agencies and consistently attracts Honours and
post-graduate students and national/international collaborators and
sabbatical visitors.
