vary by job classification.What Your Job Will Be LikeWe are seeking
a Postdoctoral Appointee to conduct reliability physics research
coupled with analysis of failure modes in power semiconductor
devices. This work aims to reveal a deeper understanding of how
extreme environments and accelerated aging factors impact the
reliability of wide-bandgap (WBG) high-power devices. This position
will also provide opportunities to become involved in other
WBG-based research projects that will expand your knowledge and
skill base. Are you interested in opportunities to augment the
existing knowledge of WBG material systems including gallium
nitride and silicon carbide? If so, you will want to consider this
opportunity, which will have you design accelerated aging
experiments to induce novel failure modes in power devices and
perform rigorous analysis to reveal electronic degradation
mechanisms. Your efforts will directly impact our understanding of
devices that will have uses in future electric grid and electric
vehicle applications.On any given day, you may be called on to:---
Work with technical staff to devise and execute accelerated stress
testing experiments of semiconductor power devices.--- Conduct
electrical testing of WBG-based high-power devices and suggest
physical analysis strategies to better understand electrical
behaviors.--- Elucidate the defect physics of these devices through
research and analysis.--- Publish research results in journal
articles and present at technical conferences.Due to the nature of
the work, the selected applicant must be able to work
onsite.Qualifications We Require--- PhD conferred within five years
prior to employment in Electrical Engineering, Materials Science,
Mechanical Engineering, Applied Physics, or a related field---
Experience in semiconductor device physics and electrical
characterization--- Experience with data analysis and control
software (e.g. MATLAB, Origin, LabVIEW)--- A proven record of
research success, demonstrated by journal publications and
conference presentations--- Ability to acquire and maintain a DOE
L-level security clearanceQualifications We Desire--- Excellent
organizational skills and the ability to work in a diverse,
multi-disciplinary team environment--- Experience with
semiconductors including conventional (e.g. Si, GaAs), wide-bandgap
(e.g. SiC and GaN), and ultra-wide-bandgap (e.g. Ga2O3, AlN,
diamond) materials--- Experience using a Keysight B1505a Power
Device Analyzer--- Experience with deep-level transient
spectroscopy tools and related techniques--- Experience with
physical semiconductor characterization techniques such as SEM,
TEM, and spectroscopies using these and related instrumentsAbout
Our TeamThe Semiconductor Material and Device Sciences Department
1873 is engaged in compound semiconductor physics and device
research, with parallel, complementary efforts in fundamental
science and novel device technologies, within 1800, the Center for
Material, Physical, and Chemical sciences. One of several current
focus areas is III-Nitride based materials and devices for power
electronics and other applications, which have enormous short- and
long-term potential for Sandia's national security missions. Other
ongoing efforts include radiation effects and defect spectroscopy,
blue and UV optoelectronics, optical metamaterials and associated
devices, and novel device concepts generally.The department's
research utilizes staff expertise in experimental and theoretical
semiconductor physics, state-of-the-art micro- and
nano-fabrication, and advanced materials and device
characterization and modeling. It partners closely with other
organizations, including the Advanced Electronic and Optoelectronic
Materials Department 1876, other departments in Centers 1300, 5200,
8800, and university and industry collaborators throughout the
world. The department makes use of state-of-the-art growth and
fabrication facilities associated with MESA (Sandia's Microsystems
Engineering, Science, and Applications complex); scientific
facilities at CINT (the joint Sandia / Los Alamos Center for
Integrated Nanotechnologies); and staff laboratories with
specialized characterization equipment.Posting DurationThis posting
will be open for application submissions for a minimum of seven (7)
calendar days, including the 'posting date'. Sandia reserves the
right to extend the posting date at any time.Security
ClearanceSandia is required by DOE to conduct a pre-employment drug
test and background review that includes checks of personal
references, credit, law enforcement records, and
employment/education verifications. Applicants for employment need
to be able to obtain and maintain a DOE L-level security clearance,
which requires U.S. citizenship. If you hold more than one
citizenship (i.e., of the U.S. and another country), your ability
to obtain a security clearance may be impacted.Applicants offered
employment with Sandia are subject to a federal background
investigation to meet the requirements for access to classified
information or matter if the duties of the position require a DOE
security clearance. Substance abuse or illegal drug use,
falsification of information, criminal activity, serious misconduct
or other indicators of untrustworthiness can cause a clearance to
be denied or terminated by the DOE, resulting in the inability to
perform the duties assigned and subsequent termination of
employment.EEOAll qualified applicants will receive consideration
for employment without regard to race, color, religion, sex, sexual
orientation, gender identity, national origin, age, disability, or
veteran status and any other protected class under state or federal
law.NNSA Requirements for MedPEDsIf you have a Medical Portable
Electronic Device (MedPED), such as a pacemaker, defibrillator,
drug-releasing pump, hearing aids, or diagnostic equipment and
other equipment for measuring, monitoring, and recording body
functions such as heartbeat and brain waves, if employed by Sandia
National Laboratories you may be required to comply with NNSA
security requirements for MedPEDs.If you have a MedPED and you are
selected for an on-site interview at Sandia National Laboratories,
there may be additional steps necessary to ensure compliance with
NNSA security requirements prior to the interview date.Position
InformationThis postdoctoral position is a temporary position for
up to one year, which may be renewed at Sandia's discretion up to
five additional years. The PhD must have been conferred within five
years prior to employment.Individuals in postdoctoral positions may
bid on regular Sandia positions as internal candidates, and in some
cases may be converted to regular career positions during their
term if warranted by ongoing operational needs, continuing
availability of funds, and satisfactory job performance.
