PhD 1: PhD studentship in Complex Multi-component Nanowire Synthesis by Solution Methods.
One of most successful synthetic methods for nanostructures is seeded (catalytic) growth of semiconductor nanowires from metal nanoparticle seeds. The goal of this project is to obtain a detailed understanding of how modulating the reactivity of various Si and Ge precursors can be used to lower nanowire growth temperatures in solution using a range of seeds from transition metals to main group metals of In, Bi and Sn. In these syntheses there is an interesting interplay between the formation of nanostructures that are silicides or germanides of the metal or the formation of single component wires. The ability to control this growth protocol will allow design of nanowires for functional applications in thermoelectrics and Batteries. The successful candidate will work in the Nanotechnology Research Group (www.nanoresearchul.org) and will have opportunities to learn from experienced researchers within the group with expertise in both chemical syntheses and advanced materials characterization using TEM, SEM, XRD, AFM etc.

PhD 2: PhD studentship in colloidal nanorod heterogeneous assembly for electrically pumped all-inorganic light emitting diodes (LEDs)
This PhD studentship is funded by Science Foundation Ireland. The successful candidate is expected to develop the fabrication procedures of nanocrystal based LEDs using heterogeneous assembly. In particular, the candidate is expected to develop methods to synthesize inorganic semiconductor quantum dots and nanorods, utilize and optimize the electric field assisted nanocrystal assembly method to form the multi-layered LED structures. The successful candidate will be integrated into two well-funded research groups in the Bernal Institute at UL – Nanotechnology Research Group (http://nanoresearchul.org/) and Nanophotonics & Nanoplasmonics Group (https://ulsites.ul.ie/physics/node/51101), and have opportunities to learn from experienced researchers within the groups with expertise in both chemical syntheses and optical characterizations.

PhD 3: PhD studentship in Ternary and Quaternary Colloidal Nanostructures containing group 14 elements
There has been an extensive body of work on the formation of ionic nanocrystals in solution (colloidal synthesis). These materials have found significant application in the fields of photovoltaics, displays and lasing. There has been considerable interest in the past few years regarding the replacement of Cd with Cu, with notable progression in capabilities to control size, shape and polytypism in these nanomaterials. This PhD project seeks to develop synthetic routes to tackle the formation of Cu2ZnGeS4 (CZGS) and Cu2ZnSnGeS4 (CZTGS) nanocrystals, compositions which have proven challenging to synthesize to-date due to the differences in the precursor reactivity. A range of different Cu, Zn, Ge, Sn and S precursors will be investigated to determine the optimal precursors and solvents/ligands that permit the stabilization of single phase CZGeS and CZTGeS nanocrystals. The successful candidate will work in the Nanotechnology Research Group (www.nanoresearchul.org) and will have opportunities to learn from experienced researchers within the groups with expertise in both chemical syntheses and advanced materials characterization using TEM, SEM, XRD, AFM etc.

PhD 4: PhD Studentship on formation of Silicon and Germanium Nanostructures on High Surface Area Anodes for Lithium ion Batteries

The exponential rise in smart phones, tablets and other portable electronics is completely reliant on rechargeable batteries of which lithium ion is the commercial battery with the highest energy density. Yet, this energy density, is in-sufficient requiring frequent recharging of devices or requiring a larger portion of the device as the battery which is infeasible from design considerations. The limitations of current lithium ion are more apparent when used for electric vehicles. Moving from graphite as the anode to Li-alloying materials such as silicon, germanium and tin can dramatically increase the energy density. However these materials can only withstand the volume changes of lithium cycling in nanostructured form. This project will investigate silicon, germanium and tin nanostructures as anodes in Lithium ion batteries. It will also investigate increasing the loading on the electrodes to maximise energy density by using porous or structured copper current collectors. The successful candidate will work in the Nanotechnology Research Group (www.nanoresearchul.org) and will have opportunities to learn from experienced researchers within the groups with expertise in both chemical syntheses lithium ion battery fabrication and testing.

PhD 5: PhD Studentship on Full Cell Lithium ion Batteries using Nanowire Anodes and Ionic Liquid Electrolytes with Conventional Cathodes
Ionic liquids have been subject of intense research in the past decades. Their high thermal stability, wide electrochemical stability window, low vapor pressure and non-flammability are, indeed, highly appealing to enable safer electrolytes. The goal of this project is to carry out the first extensive study on ionic liquids for lithium silicon batteries with the specific objectives of identifying and utilizing ionic liquid-based electrolytes for advanced Li ion energy storage. The properties of the ionic liquids will be specifically tailored for operation with Si-Ge anodes and metal oxide cathodes. The selection of appropriate anion-cation couples will be done on the basis of key parameters such as ionic conductivity, electrochemical stability, SEI forming ability and cost. The successful candidate will work in the Nanotechnology Research Group (www.nanoresearchul.org) and will have opportunities to learn from experienced researchers within the groups with expertise in both chemical syntheses lithium ion battery fabrication and testing. The successful candidate will work in the Nanotechnology Research Group (www.nanoresearchul.org) and will have opportunities to learn from experienced researchers within the groups with expertise in both chemical syntheses lithium ion battery fabrication and testing.

PhD 6: PhD Studentship in Electric field controlled assembly of functional Nanostructures
Design of Functional nanomaterials in ordered arrangements can lead to innovative properties that go way beyond the capabilities of conventional materials. For example a chequerboard arrangement of nanostructures of two different types can deliver properties that are not possible with these materials on their own or in a non-ordered arrangement and will open the door to major innovations in photonics, batteries, photovoltaics and thermoelectrics. The PhD project will involve synthesis of nanostructures and the use of electric fields to control their assembly on substrates from solution. The project will involve investigation of assembly under DC and AC field conditions. The complex nanostructured assemblies on substrates will be investigated in photovoltaic, thermoelectric and photonic applications. The successful candidate will work in the Nanotechnology Research Group (www.nanoresearchul.org) and will have opportunities to learn from experienced researchers within the group with expertise in both chemical syntheses and electric field assembly techniques.
