Overview
The U.S. Army DEVCOM Army Research Laboratory (ARL), located in Adelphi, MD, outside of Washington, DC, is seeking Postdoctoral Fellows interested in the physics of wide and ultra-wide bandgap (UWBG) semiconductor electronic and optoelectronic devices. Fellows will have the opportunity to conduct their research using a wide variety of experimental capabilities. Areas of active research include:
UWBG Semiconductor Carrier Dynamics
—Optical spectroscopy using ultrafast and continuous wave lasers and other light sources spanning the 200 nm to 2500 nm spectral range along with a picosecond pulsed electron source, coupled to experimental techniques such as time-resolved and continuous wave photoluminescence, cathodoluminescence, electron beam induced current, Terahertz spectroscopy, and other pump-probe photomodulation spectroscopies such as photoreflectance, electroreflectance, and both time domain and frequency domain thermoreflectance.
Growth of III-Nitride Materials and Device Structures
—Plasma-assisted molecular beam epitaxy (MBE) and metalorganic vapor-phase epitaxy (MOVPE) of UWBG semiconductors and novel device designs with access to RHEED, XRD, SEM, AFM, and Hall Effect characterization tools.
High Power Electronic and UV-Optelelectronic Devices
—Next generation power switching devices, UV-lasers and LEDs, and UWBG semiconductor detectors; design and fabrication with access to ARL’s Specialty Electronic Materials and Sensors Cleanroom (SEMASC) which includes e-beam and direct write laser lithography; atomic layer, e-beam evaporator, plasma chemical vapor, and sputtering deposition; as well as various etching techniques. Device packaging and testing, including auto probers, high-field measurements, as well as detector testing and LED/laser characterization systems with an emphasis on device efficiency and thermal transport problems.
Semiconductor Theory and Device Modeling
—3D full band Monte-Carlo calculations, DFT, non-equilibrium Green’s function techniques, commercial TCAD packages, to understand materials and device physics all within the ARL Modeling Research Environment.
Research projects can focus on a specific problem or take an idea from conception to production. Fellows will have the opportunity to collaborate with a multidisciplinary team as well as with academic and industrial research groups.
