Elaine Carroll

Elaine Carroll is a Cork woman. She received her B.Sc. in Applied Physics from the University of Limerick in 2011, and is currently working towards her Ph.D. degree. Her research focuses on the exfoliation of 2D crystals and paintable layered materials, their structural, electrical and thermal characterisation. The aim is to fundamentally study the link between the physical properties of single-molecule thick materials and paintable thin films, and their temperature-dependent charge transport characteristics  for thermoelectrics.
