Linear and Helical Cesium Iodide Atomic Chains in Ultranarrow Single-Walled Carbon Nanotubes: Impact on Optical Properties.

| Description | We have developed new modelling capabilties to understand nanowires encapsulated within carbon nantubes. Our goal was to characterise these new materials and use these techniques to seach for phase transitions that could be used in phase-change memory. Our key finding so far are: 1. Helical-tellurium encapulsate nanowires including the predition of an electronic insulator-conducting transition. 2. Through first-principles modelling enhancemnt to electrical conductivity of carbon nanotubes using a nanowire filling. 3. Crystalline-Crystalline temperature induced structural phase transitions in encapsulated GeTe. |
| Exploitation Route | * Developments in computer chips through carbon nanotube higher current interconnects. * Nano-encapsulated phase change memory for electronic devices. |
