About the group

Molecules, interfaces, and electron transfer

We are scientists and students investigating molecular systems and electronic processes with computer simulation. Our group is based in the Department of Physics at the Faculty of Science, University of South Bohemia in České Budějovice, Czech Republic. The group is led by Zdeněk Futera.

What we study

Research areas

01 / Bioelectronics

Electron transport in protein junctions

We study how electrons move through redox proteins connected to electrodes. Our work examines when transport proceeds by hopping between redox sites and when coherent tunneling can dominate.

We combine classical molecular dynamics, hybrid quantum-mechanical / molecular-mechanical methods, and density functional theory.

02 / Interfaces

Electric fields at heterogeneous interfaces

Applied electric fields can change the structure and electronic properties of biomolecules at electrode surfaces. We investigate these effects and field-driven chemistry at bio/metallic and aqueous interfaces.

Our simulations use non-equilibrium molecular dynamics, classical force fields, and density functional theory.
