Research Scientist, Data Scientist
The Material Measurement Laboratory of the National Institute of Standards and Technology (NIST) is seeking qualified persons (U.S. citizens preferred) to develop a multi-scale modeling infrastructure for the predicting the properties and performance of advanced semiconductor materials and devices. This position will focus on using classical atomistic methods to explore the crystalline defects present in semiconductor devices and what impact they may have on device properties.
A key aspect of the work will be to explore how the predicted defects and properties depend on the choice of interatomic potential. The calculations will largely focus on interface-driven phenomena in GaN-based semiconductor devices.
- Testing classical interatomic potentials for how well they predict defect properties.
- Developing a new interatomic potential for GaN-based semiconductor devices.
- Generating atomic configurations of grain and phase boundary interfaces to explore predicted defects for stable and metastable conditions across multiple potentials.
- Working with other researchers in the project to communicate needs and results across the different length scales.
- Implementing calculation methods into existing open-source codes and ensuring that all generated data is made accessible.
- Ph.D. in Materials Science and Engineering or a related field.
- Experience with using LAMMPS to perform atomistic simulations.
- Experience with crystalline defects, interface-driven phenomena and microstructure evolution.
- Experience looking at trends in computed atomistic predictions across different materials and interatomic potentials.
- Excellent written and oral communication skills.
This opportunity is to be an associate researcher in the NIST Material Data Division for a term of 1 year, with options to renew. Associate researchers are NOT Federal Employees, but they work along with NIST researchers and with NIST’s world-class instrumentation. Relocation expenses will not be provided. U.S. citizens hired into associate positions may have the opportunity to seek longer term Federal Employment.
Between $82,000 and $87,000, based on qualifications and experience
