Current Projects

Modelling of Phase-Change materials for memory

EPSRC grant EP/F015046/1

Electronic phase-change random access memory (PCRAM), also known as Ovonic, offer excellent prospects for improved solid state storage devices. Although much progress has been made in the fabrication, the understanding of the electronic, structural and switching properties at the core of this new technology is rather limited. We use diverse modelling techniques (from TD-DFT to classical MD) to investigate the properties of the chalcogenides GeSb2Te4 and Ge2Sb2Te5.

Molecular Frameworks for Metamaterials

Combines chemical (atomistic) and traditional mechanical modeling (Finite Elements) to cast some light on the mechanisms behind extraorndinary elastic properties succh as Auxeticity (Negative Poisson Ratio) , NTE (Negative Thermal Expansion) and NLC (Negative Linear Compressibility). The materials I am interested in range from zeolites, precious metal sulfides/oxides and meta-carbons to scale-less scaffold inspired from the former.
