Research interest

My research at ICMAB is mainly devoted to heat transport simulation. I have developed an efficient computational software for atomistic quantum phonon transport  based on nonequilibrium Green's functions that can be applied to study lattice thermal transport problems in multiple crystalline materials. I combine this type of simulations with classical molecular dynamics on different heterostructured materials, ranging from ferroelectric domain walls to semiconductor nanowires or molecular systems, to devise heat transport functionalities such as thermal switchers, filters or rectifiers with potential applications in the field of phononics.

In parallel, I am continuously active in the research on semiconductor core-multishell nanowires, a topic in which I have been working since 2011. In particular I am interested in the electronic, magnetotransport and optical properties of free electron and/or hole gases accumulated in modulation-doped radial nanowire heterojunctions.
