Quantum transport in topological van der Waals nanocrystals

E-mail : ideue[at]


I am studying the characteristic transport and optical properties in van der Waals nanostructures.

By using the ionic liquid gating or exfoliation/transfer techniques, I will engineer the symmetry of van der Waals interfaces and search for the novel Physical properties and functionalities such as nonreciprocal transport and anomalous photovoltaic effect.
