Postdoctoral Appointee - Nanocarbon Film Research

Sandia National Laboratories

Albuquerque, NM

Job posting number: #7061721 (Ref:669616)

Posted: October 23, 2019

Job Description

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. : We seek Postdoctoral Appointees to conduct leading-edge experimental research in the growth and characterization nanocarbon films, including carbon nanotube (CNT) arrays, nanoporous carbon (NPC), and diamondlike carbon (DLC). You will be part of an interdisciplinary team of scientists and engineers so your work can achieve greater impact. CNT arrays will be grown using nanopore template-assisted chemical vapor deposition; the focus will be to optimize template fabrication and study the resulting CNT and array structural properties as a function of controlled growth. Nanopore templates are fabricated onto a substrate-of-choice using sputter deposition of metal films followed by electrochemical anodization. The goal is to fundamentally understand the relationships between CNT array structure qualities and the resulting array thermal properties. Both NPC and DLC films will be grown using pulsed-laser deposition (PLD) and studied for use in electrochemical energy storage systems (e.g. batteries, supercapacitors). Study will focus on controlling the resulting film structures and correlating them with relevant electrochemical properties. NPC films are also used for chemical microsensors. Other opportunities for these materials may present themselves based on discovery. In addition, other materials-related projects will likely arise over time. Key functions of this role include, but are not limited to: + Performing original studies correlating the growth of controlled material structures and compositions with desired properties (e.g. thermal, electrochemical) + Engaging in laboratory activities related to the synthesis, post-processing, and structural characterizations of nanocarbon film materials + Demonstrating leadership and self-motivation within a team-oriented environment + Publishing findings in leading journals and presenting at scientific conferences

+ A PhD in materials science, physics, applied physics, engineering, or a related discipline completed prior to reporting for the position, and a bachelor's in science, technology, engineering or mathematics (STEM) + Experience in thin film materials growth and characterization + Record of original work to include conference presentations and publications in refereed journals + Able to obtain and maintain a DOE L Security Clearance

+ Experience in film growth methods (e.g. pulsed-laser deposition, chemical vapor deposition, sputtering) + Experience with various post-deposition processes such as:thermal annealing, ion beam milling, and anodization and electrochemical depositions + Experience making electronic and/or thermal transport measurements + Experience making and/or interpreting structural measurements (e.g. electron microscopies, stress evaluation, Raman, AFM) + Ability to develop and maintain collaboration with leaders in the scientific community within and outside of Sandia National Laboratories + Curiosity about the world and a strong interest in connecting one's research to the larger context of science, society, and national security + A record of academic achievement as demonstrated by high GPAs for relevant undergraduate degree(s) and graduate degree(s) + Effective communication and interpersonal skills that foster effective scientific collaborations with a diverse population of researchers + Candidates should also have demonstrated creative problem solving and effective time management skills

Department Description:

The Nanoscale Sciences Department conducts collaborative leading-edge research that advances the understanding of materials at the nanoscale and enables the collaborative development of creative solutions for Sandia's broad and evolving National Security and Energy Missions.

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 Statement:

All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status.
