Postdoctoral Researcher ( PREP0002399)

Johns Hopkins, founded in 1876, is America's first research university and home to nine world-class academic divisions working together as one university.

Description

PREP Research Associate
CHIPS Funded Project.

This position is part of the National Institute of Standards (NIST) Professional Research Experience (PREP) program. NIST recognizes that its research staff may wish to collaborate with researchers at academic institutions on specific projects of mutual interest and thus requires that such institutions be the recipients of a PREP award. The PREP program requires staff from a wide range of backgrounds to work on scientific research in many areas. Employees in this position will perform technical work that underpins the scientific research of the collaboration.

Research Title:

CHIPS Postdoc for Density Functional Theory Workflow

The work will entail:

using density functional theory to predict electronic properties of semiconductor devices. Some of the key properties include bandgaps, band alignments and transport properties of interfaces, especially for metal-semiconductor, insulator-semiconductor heterostructures. Some of the materials of interest for interface design include Si, GaN, AlN, Al2O3, HfO2, Al, Cu.

Key responsibilities will include but are not limited to:

▪ Development of a streamlined workflow to conduct high-throughput calculations for semiconductor-specific properties, including transport properties.

▪ Development of a Python package to generate industry-relevant atomistic structures for material interfaces and heterostructures

▪ Simulate coherent and semi-coherent interfaces, reconstruction effects, amorphous materials, as well as the incorporation of point and line defects within the interfaces,

▪ Calculate properties such as bandgaps, band offsets, Schottky barriers, current-voltage curves, mobility, and thermal conductivity. This will involve the utilization of software tools such as VASP, Quantum Espresso, QuantumATK, or similar platforms

▪ Benchmarking calculations with respect to available experimental data,

▪ Design and implementation of surrogate models for the generated data to expedite the interface design process using specialized software such as ALIGNN.

Qualifications

▪ A Doctorate in Materials Science and Engineering, Physics or a related field.

▪ 4 years of relevant experience.

▪ Experience with using VASP, Abinit or QuantumATK to perform atomistic simulations.

▪ Experience with using Scikit-Learnt to perform machine learning surrogate model development.

▪ Familiarity with Python.

▪ Strong oral and written communication skills.

The following additional provisions may apply depending on which campus you will work. Your recruiter will advise accordingly.

The pre-employment physical for positions in clinical areas, laboratories, working with research subjects, or involving community contact requires documentation of immune status against Rubella (German measles), Rubeola (Measles), Mumps, Varicella (chickenpox), Hepatitis B and documentation of having received the Tdap (Tetanus, diphtheria, pertussis) vaccination. This may include documentation of having two (2) MMR vaccines; two (2) Varicella vaccines; or antibody status to these diseases from laboratory testing. Blood tests for immunities to these diseases are ordinarily included in the pre-employment physical exam except for those employees who provide results of blood tests or immunization documentation from their own health care providers. Any vaccinations required for these diseases will be given at no cost in our Occupational Health office.
