Percolation transport in nanostructure networks Percolation transport deals with the formation of long-range connectivity in random networks.  Our recent work on the effect of nanowire curviness on the percolation resistivity of transparent, conductive metal nanowire networks, where we studied… Read More

Transparent, conductive, and flexible electrodes based on carbon nanotubes and graphene Carbon nanomaterials, such as carbon nanotube (CNT) films and graphene exhibit good electrical conductivity, high optical transparency, and mechanical flexibility.  As a result, they are excellent candidates for next generation transparent,… Read More

Mixed-dimensional van der Waals Schottky junctions between nanomaterials and conventional semiconductors For most device applications of nanomaterials, interfaces and junctions play a significant role.  Mixed-dimensional van der Waals heterojunctions are formed by stacking materials with different dimensionality through non-covalent van der… Read More

Nanoscale molecular sensors Nanoscale materials have naturally small size, extremely high surface-to-volume ratio, low noise, and low-power consumption.  As a result of these significant advantages, they are excellent candidates for molecular gas and vapor sensors.  Furthermore, selectivity to different gas… Read More
