Los Alamos National Laboratory Solid State Detectors Postdoc Research Associate in Los Alamos, New Mexico

What You Will Do

We are seeking a postdoctoral research associate to join our Team within the Materials Physics and Applications Division at Los Alamos National Laboratory (LANL) to conduct research on hybrid perovskite based detectors. The aim of the project is to fabricate solid-state detectors utilizing hybrid perovskite materials (crystals and thin films) to detect high-energy (X-rays, gamma-rays, charged particles, etc.). Along with this goal, basic and novel carrier transport and recombination properties, electron-phonon coupling and carrier collection correlated to the structure will be studied. The successful candidate will be expected to contribute to the device fabrication and characterization, as well as connecting this information to understand the materials structure-function properties under excitation.

We therefore invite applicants who are interested and experienced in working on hybrid perovskite materials and electronic device fabrication to apply. Focused research topics will include: 1) device fabrication and characterization; 2) understanding the device operation physics, dark/photo conductivity and loss mechanisms; 3) carrier extraction and transport in a thin film detector under external fields (electrical or magnetic); 4) contact optimization, including using carbon electrodes to reduce radiation beam absorption and interface engineering to suppress interfacial recombination. The candidate will also be encouraged to explore novel device functionalities within the scope of detection; for example, new device architecture design, novel carrier extraction schemes and measurements for ultra-fast device response.

What You Need

Minimum Job Requirements:

  • Demonstrated hands-on experience in the following:

  • Extensive device fabrication and optimization experience.

  • In-depth device characterization skills, including carrier extraction, photocurrent transient, impedance spectroscopy, and temperature dependent conductivity measurements.

  • Capability of building experimental setups (e.g. lock-in amplifier, function generator, DC power, low noise circuits) and making electrical connections.

  • Demonstrated experience in conducting original scientific research through peer reviewed publication record.

  • Basic knowledge on optical measurements (absorption, photoluminescence)

  • Excellent communication skills (both oral and written)

Desired Skills:

  • Knowledge on basic device characterizations (JV, impedance spectroscopy, photoconductivity, current transient and mobility measurements)

  • Capabilities for LabVIEW programming.

  • Demonstrated ability to work independently and with minimum supervision.

  • Ability to adapt to new requirements for projects and be flexible enough to learn new areas of research as needed.

  • Able to work effectively as a part of a team in a multi-disciplinary environment and interact effectively with people with a variety of expertise

Education:

A PhD in Applied Physics or related fields, completed within the last five years or soon to be completed.
