Trinity College Dublin is seeking applications for postgraduate researcher positions to participate in an SFI funded study on the structure, electrical and mechanical properties of nanoscale crystalline metals. Nanoscale metal materials have anomalous properties that are having a growing impact on the performance of device technologies. For example, nanocrystalline copper wires form essential interconnects between devices. As device dimensions are scaled-down the resistivity of these wires is known to significantly increase, limiting the performance and battery life of all hand held devices.
This study will involve both experiment and simulation. Experiment will include cryogenic STM and AFM studies of nanocrystalline metal films and will focus on the atomic-level structure of grain boundaries and their role in controlling properties. Researchers will gain experience on the use of cryogenic STM/AFM, growth and process of nanocrystalline films and electrical and nanomechanical characterisation. Theory work will include the calculation of the electronic and transport properties of novel materials and composites and will involve state-of-the-art density functional theory combined with quantum transport. Individual project will in addition focus on (i) electronic properties, (ii) mechanical properties, and (iii) simulations of grain boundaries in nanocrystalline metal films.
Applicants must have a first-class honours BSc or MSc degree in physical chemistry, physics or material science from an internationally reputable university and provide a curriculum vitae, academic transcripts, a statement of research experience, together with the contact information for three references.
