Metal Nitride Sythesis and Spectroscopic Characterization Postdoctoral Scholar
Lawrence Berkeley National Laboratory
June 9, 2018
Berkeley, United States
Berkeley Lab's Chemical Sciences Division has an opening for a Metal Nitride Sythesis and Spectroscopic Characterization Postdoctoral Scholar. The Joint Center for Artificial Photosynthesis (JCAP) has the mission of discovering and demonstrating components for photoelectrochemical devices that will convert CO2 to liquid fuels with high efficiency and selectivity using sunlight. Light is harvested and converted using photoelectrodes based on a variety of semiconductor material systems. While metal oxides provide a foundational research program, establishing new classes of materials will be critical to achieving stability and efficiency demands. One such class of materials are the metal nitrides, which in comparison to their oxide counterparts offer direct and reduced bandgaps and higher mobilities. To realize the full potential of these materials systems, we require lowered cost of production, surface areas greater than 1 cm2, a high degree of reproducibility, and deposition on a variety of conductive substrates.
JCAP currently has a Postdoctoral research opportunity to develop an electrochemical route to the production of nitride semiconductors. The selected candidate will complete the designs of a liquid ammonia electrochemical reactor cell based on a Schlenk line system. The electrochemical method will be validated on several material systems to establish phase purity and electrical quality. The materials will be characterized for their photoelectrochemical conversion of CO2 and/or other sequential reactor designs for the production of liquid fuels. The optoelectronic properties of the thin film materials will be extensively examined by a variety of optical and x-ray probes. In JCAP's highly collaborative environment, s/he will work closely with other researchers performing measurements on a day-to-day basis. A close working relationship with theoreticians will be a key aspect to the success of the project. The successful candidate will be expected to provide project updates, presentations, and posters based on research progress to the JCAP community.
What You Will Do:
Develop the capabilities for the electrochemical formation of metal nitride semiconductors.
Characterize the light harvesting performance of the nitride materials in photoelectrochemical cells.
Characterize the optical and electronic properties of materials for solar energy harvesting.
Work closely with theoreticians to develop models of electronic structure, native defects, and carrier transport properties.
Have a current Job Hazards Questionnaire (or equivalent) on file.
What is Required:
PhD. in material or chemical science/engineering, with a strong background in synthesis and characterization.
Expertise with electrodeposition and electrochemistry.
Expertise with air-free methods such as Schlenk line and glove boxes.
Experience with materials characterization such as: Raman, UV-Vis, ellipsometry, XRD, SEM, EDX, XPS, and photoluminescence.
Ability to work as an independent researcher with a high level of scientific judgment and initiative.
Excellent teamwork, organizational, and communication skills.
Demonstrated ability to prepare results for oral reports and for publication in archival journals.
Additional Desired Qualifications:
Working knowledge or experience with: Hall effect, impedance spectroscopy, and/or transient photocurrent.
Working knowledge or experience with: Transient absorption spectroscopy.
Working knowledge or experience with X-ray spectroscopies including: XAS, XES, EXAFS, RIXS.
The posting shall remain open until the position is 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. You must have less than 4 years paid postdoctoral experience. Salary for Postdoctoral positions depends on years of experience post-degree.
Full-time, M-F, exempt (monthly paid) from overtime pay.
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.

About Lawrence Berkeley National Laboratory
In the world of science, Lawrence Berkeley National Laboratory (Berkeley Lab) is synonymous with excellence. Thirteen scientists associated with Berkeley Lab have won the Nobel Prize. Fifty-seven Lab scientists are members of the National Academy of Sciences (NAS), one of the highest honors for a scientist in the United States. Thirteen of our scientists have won the National Medal of Science, our nation's highest award for lifetime achievement in fields of scientific research. Eighteen of our engineers have been elected to the National Academy of Engineering, and three of our scientists have been elected into the Institute of Medicine. In addition, Berkeley Lab has trained thousands of university science and engineering students who are advancing technological innovations across the nation and around the world. Berkeley Lab is a member of the national laboratory system supported by the U.S. Department of Energy through its Office of Science. It is managed by the University of California (UC) and is charged with conducting unclassified research across a wide range of scientific disciplines. Located on a 200-acre site in the hills above the UC Berkeley campus that offers spectacular... views of the San Francisco Bay, Berkeley Lab employs approximately 4,200 scientists, engineers, support staff and students. Its budget for 2011 is $735 million, with an additional $101 million in funding from the American Recovery and Reinvestment Act, for a total of $836 million. A recent study estimates the Laboratory's overall economic impact through direct, indirect and induced spending on the nine counties that make up the San Francisco Bay Area to be nearly $700 million annually. The Lab was also responsible for creating 5,600 jobs locally and 12,000 nationally. The overall economic impact on the national economy is estimated at $1.6 billion a year. Technologies developed at Berkeley Lab have generated billions of dollars in revenues, and thousands of jobs. Savings as a result of Berkeley Lab developments in lighting and windows, and other energy-efficient technologies, have also been in the billions of dollars. Berkeley Lab was founded in 1931 by Ernest Orlando Lawrence, a UC Berkeley physicist who won the 1939 Nobel Prize in physics for his invention of the cyclotron, a circular particle accelerator that opened the door to high-energy physics. It was Lawrence's belief that scientific research is best done through teams of individuals with different fields of expertise, working together. His teamwork concept is a Berkeley Lab legacy that continues today.
