Molecular/semiconductor hybrid nanostructures

Molecular electronics uses individual or assemblies of molecules as active components and/or wiring; it represents the ultimate miniaturization of micro/nano electronics. Molecules with specific terminal groups can also be employed as the “glue” for bottom-up directed self-assembly of semiconductor nano components into functional devices and circuits. We explore the fabrication, assembly, electronic characterization, and device functionality of a variety of hybrid nanostructures of organic molecules and crystalline semiconductors. Specific research activities include:

  • Directed self-assembly of carbon nanotube field-effect transistors and other nanostructures.

  • Creating new device functionalities and enhancing device performance by molecular interfaces.

  • Semiconductor devices (FETs and micro-Hall magnetometers) as portable biomolecular sensor.


  • Controlled modulation of magnetism in magnetic semiconductors using surface organic molecule.

  • Chirality-induced spin selectivity (CISS)
