Postdoctoral Opportunity – THz Sensor Technology

We are seeking qualified and talented postdoctoral candidates to join our team in summer 2018 to work on a project to develop uncooled THz sensors for space applications.  The selected individual will work on a NASA-supported program to develop an uncooled THz heterodyne sensor based on the photo‐thermo‐electric effect in graphene. The proposed sensor is being studied for potential use in in future space flight missions to the icy moons of Jupiter and Saturn, which seek to assess the presence of pre-biotic organic molecules in the atmospheres of these moons. This experimental project will include lithographic processing of graphene terahertz devices, measurements of the THz response, noise and bandwidth characterization, as well as antenna design and modeling.

Essential skills and experience sought:

  • PhD awarded (or expected) in Applied Physics, Engineering, Physics, or related field
  • Excellent communication skills (in writing and speaking)
  • Cleanroom fabrication experience (photolithography, e-beam lithography, etching, deposition)
  • Experience with DC and microwave electrical characterization of devices

Desirable skills include:

  • Numerical modeling, design, and optimization of THz and microwave devices (HFSS, CST, Comsol)
  • Processing and characterization of 2D materials
  • Experience with THz measurements and instrumentation (bolometers, mixers, FTIR)
  • Microwave measurements and instrumentation (spectrum/network analyzers, noise metrology)

Interested applicants should email Thomas E. Murphy ( or H. Dennis Drew ( with a CV and list of potential references.
