What Your Job Will Be Like:
We 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 clearance
Qualifications 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 instruments
About Our Team:
The 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 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 Duration:
This 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 Clearance:
Sandia 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.
EEO:
All 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 MedPEDs:
If 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 Information:
This 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.
