Berkeley Lab’s Material Sciences Division has an opening for a Synchrotron and Laser ARPES Postdoc to fill immediately.
The Advanced Light Source is a recognized world leader in synchrotron-based ARPES, pushing the boundaries in spatially-resolved nanoARPES. The Material Sciences Division’s Ultrafast Program houses an extensive array of laser-based pump-probe ARPES and other time-resolved tools. The program is seeking a recent Ph.D. graduate scientist to engage in a joint program to combine a pump laser into the ALS nanoARPES x-ray beamline for unique experiments targeting the electronic structure basis of exciting metastable phase transitions in quantum materials. The nanoARPES beamline endstation enables ARPES electronic structure measurements with beam spot sizes in the range of 1 um to 100 nm, along with the ability for in-situ transport measurements and the application of electric fields and mechanical strain. You will play a central role in developing a program that integrates laser excitation into the nanoARPES beamline to combine high fluence IR excitation with x-ray nanoprobe ARPES. You will apply this capability to understand the nanoscale electronic structure evolution of quantum phase transitions across multiple length and time scales.
What You Will Do:
- Establish integration of pulsed fs laser beam into synchrotron beamline, co-focused with x-ray beam onto sample position.
- Participate and contribute to development of laser optical systems for use at the beamline.
- Carry out original nanoARPES research in quantum material phase transitions through the in-situ application of fields, currents, strain, and photoexcitation.
- Explore use of range of tools available at the beamline (nanoARPES, microARPES, LEEM, PEEM) with those in the ultrafast labs (time-resolved ARPES, IR and THz spectroscopies) to probe quantum phase transitions through multiple time and length scales.
- Develop and utilize innovative methods and procedures for analyzing nanoARPES data and its relationship to other techniques.
- Prepare research publication, and communicate results at professional meetings.
What is Required:
- Ph.D. or equivalent degree in Materials Science, Physics, or related Physical Sciences or Engineering discipline.
- Excellent scientific publications record demonstrating knowledge and experience with optical/ultrafast experiments and laser system use/design/optimization; and/or ARPES, nanoARPES, and/or time-resolved ARPES.
- Strong interest in developing new, and improving, instrumentation and/or techniques.
- High self-motivation and independence; can take ownership of projects.
- Ability to work effectively within a team and with various levels of internal and external users and staff.
- Strong organizational and time management skills. Ability to manage competing priorities.
- Experience with designing, commissioning, aligning, and/or using laser / optical systems.
- Experience with optomechanics and motion control.
- Experience with nanopositioning systems.
- Experience in the application of machine learning and/or artificial intelligence methods for the analysis of imaging or spectroscopic data.
Requested Application Materials:
- Statement of research experience (1 page).
This position will remain open until filled.
- This is a full-time, 1-year, postdoctoral appointment with the possibility of renewal based upon satisfactory job performance, continuing availability of funds, and ongoing operational needs. Salary for Postdoctoral positions depends on years of experience post-degree.
- This position is represented by a union for collective bargaining purposes.
- You must have less than 3 years of paid postdoctoral experience..
- Salary will be predetermined based on postdoctoral step rates.
- This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.
- Work will be primarily performed at Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA.
