Nanofabrication and Metrology Specialist
Qualifications
- A PhD degree in experimental condensed matter physics.
- Five years of experience in fabricating nanoscale patterns at complex oxide interfaces using
conductive atomic force microscopy (c-AFM) and ultra-low voltage electron beam lithography (ULV-
EBL). - Three years of experience in nanoscale patterning of ferroelectric materials, using ultra-low voltage
electron beam lithography. - Five years of experience in cleanroom-based nanofabrication of nanoelectronics and quantum
devices, including layout design, fume hood, resist-based lithography (photolithography and
electron-beam lithography), thin-film deposition and etching. - Three years of experience in fabricating two-dimensional layered material devices, including
graphene and hexagonal boron nitride heterostructures stacking and transferring. - Five years of experience in electrical transport measurements at ultra-low temperatures.
- Five years of experience in radio frequency (RF) measurements at ultra-low temperatures.
- Five years of experience in the maintenance and operation of a dilution refrigerator.
- Five years of experience in handling cryogens, including liquid helium transfer.
- Experience in operating a multi-modal measurements scanning probe system, including STM, AFM,
and electrical transport measurements in a single system operating at ultra-low temperatures and in
ultra-high vacuum. - Experience in the preparation of atomically sharp probe tips for STM and AFM measurements.
- Experience with ultra-high vacuum (UHV) techniques, including assembly, types of UHV pumps, in-
situ ion sputtering, and reflection high-energy electron diffraction (RHEED) measurements. - Experience in dilute atom evaporation in UHV for SPM experiments on single isolated deposited
atoms. - Five years of experience in research of complex oxide physics, including in LaAlO 3 /SrTiO 3 (LAO/STO)
heterostructures, with a least three peer-reviewed publications. - Three years of experience in research of 2D quantum materials, including graphene-based
heterostructures and related van der Waals materials. - Research experience in superconducting materials.
- Research experience with SPM probe-based superconducting Josephson junctions.
- Five years of experience in developing and programming LabVIEW VIs for electrical transport
measurements and spectroscopic mapping of STM and AFM measurements on the Nanonis SPM
control system platform. - Five years of experience in developing and programming LabVIEW Vis for general instrument control
and transport measurements. - U.S. Citizen Preferred
Research Proposal
Key responsibilities will include but are not limited to:
- Designing and fabricating van der Waals heterostructure devices, including rhombohedral
graphene and twisted graphene multilayers, for investigation with scanning probe microscopy. - Fabrication of superlattices in 2d materials via e-beam lithography.
- Perform measurements with scanning probe microscopy techniques.
- Presenting results at internal meetings, and occasional meetings with external stakeholders.
- Ensuring that results, protocols, software, and documentation have been archived or otherwise
transmitted to the larger organization.
