Position Description: The Atomic-scale Quantum Devices (A-sQuaD) research effort at the Laboratory for Physical Sciences (LPS) makes use of unique capabilities to fabricate atomically-precise, dopant-based devices in semiconductor materials and explore novel phenomena related to dopant-bound electron and hole spins. We are currently seeking a highly-motivated, dedicated and innovative postdoctoral researcher to perform foundational experiments for one of the following projects: • Dopant spin qubits in silicon and/or germanium • Realization of Si-based superconducting qubit devices This research project will leverage state-of-the-art, UHV-STM, atomic-precision fabrication capabilities pioneered by the LPS Atomistic Fabrication team to realize acceptor-based qubit devices in either silicon or germanium. The fabrication processes will be complemented by electrical characterization to perform single spin measurements and/or demonstrate superconductivity in Si. This highly collaborative project provides opportunities for networking with pre-eminent national labs and academic research groups. Minimum Qualifications: • Ph.D. in Physics, Materials Science, or Electrical Engineering with extensive experience in operating and maintaining UHV-STM or cryogenic measurement systems • One or more of the following areas of expertise: o Scanning probe microscopy (STM or AFM); o RF engineering for spin qubit manipulation and readout; o Silicon surface chemistry; o Cleanroom device processing; o Optical and e-beam lithography; o Magnetotransport of mesoscopic systems; o Experience with scientific computing, such as C++, Python, or MATLAB. In addition to technical skills, the ideal candidate should have a strong publication record and be able to work collaboratively with and guide a research team consisting of graduate and undergraduate students. Research will be performed at LPS with a 2-year appointment with a possibility for renewal through the University of Maryland – College Park. Application Materials Required: Qualified applicants should submit the following to the LQC at lqc@lps.gov: • CV • List of publications • Contact information for at least two references.
