This project aims to develop a prototype electric field induced second harmonic generation metrology setup for studying thin film dielectric interfaces on silicon in partnership with Femtometrix. The quality of these silicon-dielectric interfaces, which are affected by trapped charges and defects, are critical for microelectronic and optoelectronic device manufacturing. Through several proposed methodologies to separate the effect of interface and bulk signals, it is expected that the sensitivity of the prototype setup will exceed the previous record of 1 kV/cm. This metrology technique will be further expanded for applicability to silicon photovoltaics, specifically passivating contacts which cannot be studied via conventional techniques.Read moreRead less
Revealing the atoms that control performance in photoactive perovskites. This project aims to develop new electron microscopy techniques that will unambiguously determine the elusive structures of photoactive perovskite compounds under static and operational conditions, while correlating crystal structure with solar cell device performance. Photoactive perovskites are promising photovoltaic materials, however, many are sensitive to air and irradiation. This has impeded a huge international resea ....Revealing the atoms that control performance in photoactive perovskites. This project aims to develop new electron microscopy techniques that will unambiguously determine the elusive structures of photoactive perovskite compounds under static and operational conditions, while correlating crystal structure with solar cell device performance. Photoactive perovskites are promising photovoltaic materials, however, many are sensitive to air and irradiation. This has impeded a huge international research effort to determine their structure reliably at the atomic scale. With these new techniques applied to leading compounds and devices, it is expected this project will reveal the structural effects controlling electrical properties and device performance and so enable the design of superior perovskite photovoltaics.Read moreRead less

This project aims to develop deep structure-property relationships and strain engineering protocols to generate stable forms of the emerging inorganic halide perovskite semiconductors, which are promising for next-generation solar cells and light emitting diodes. This project expects to arrive at working light emitter and detector prototypes via a three-dimensional, multi-length scale strain engineering approach that utilises materials processing techniques already used in the semiconductor industry. The expected outcomes include the development of new stabilisation methods which are compatible with facile and scalable device processing, which will directly impact the success of future perovskite optoelectronic devices and technologies.Read moreRead less

In situ electron microscopy toward new materials and applications. This project aims to develop materials for structural and green energy applications, using spatially-resolved, dynamic in situ transmission electron microscopy to research fundamental mechanical, electrical, thermal, optical, optoelectronic and photovoltaic properties of diverse nanostructures. These techniques measure nanomaterial (one-dimensional nanotubes and nanowires and two-dimensional graphene-like nanosheets) response to external stimuli, including mechanical, electrical, optical and thermal stimuli. Anticipated outcomes are new ultralight and superstrong structural composites and ‘green-energy’ nanomaterials, such as solar cells, touch panels, batteries, supercapacitors, field-effect transistors, light sensors and displays.Read moreRead less
Charge and energy transport in disordered functional materials. This project aims to understand how energy and electric charge move through disordered materials. Many next-generation materials—including organic semiconductors, hybrid perovskites, and conductive metal-organic frameworks—promise better solar cells, sensors, and electrocatalysts; however, they remain incompletely understood because they are disordered and noisy systems that are difficult to describe mathematically.

Many next-generation materials—including organic semiconductors, hybrid perovskites, and conductive metal-organic frameworks—promise better solar cells, sensors, and electrocatalysts; however, they remain incompletely understood because they are disordered and noisy systems that are difficult to describe mathematically. This project expects to develop the first theoretical techniques that capture all essential features of transport in disordered materials. The resulting understanding of structure-function relationships should accelerate the rational design of cutting-edge devices for energy conversion and storage.Read moreRead less
