Computational Nanodevices - Exploring Small Wonders


Our research work in computational nanodevices focuses on developing simulation and design tools and exploring scientifically and technologically important problems for nanoscale devices using computer modeling and simulations. More specifically, we work on:

  • Nanotube/Nanowire Electronics: exploring promising new device options beyond the scaling limit of conventional Si MOSFETs using one-dimensional nanostructures as transistor channels
  • Nanotube/Nanowire Optoelectronics: High quality, direct bandgap nanotubes/nanowires not only possess superior electrical transport properties, but also can emit or detect light. For example, the smallest solid state light emitter and photodetector made to date are based on carbon nanotubes
  • Chemical/Biological Nanosensors: sensors based on nanowires/nanotubes promise the potential advantages of small size, low power, high sensitivity, and low cost.
  • Device Physics of Nanotransistors: as transistors scale down to the nanometer scale, a new picture for understanding transistor characteristics is called for.
  • Carrier Transport in Nanodevices: quantum transport is necessary for understanding nanoscale devices.
