Profile bio
About Stephen Schaefer
I am a postdoctoral researcher specializing in growth of ultra-wide bandgap semiconductor materials by molecular beam epitaxy (MBE). Materials of interest include gallium oxide and novel ternary nitrides. I joined NREL in August 2022. Previously, I worked as a postdoctoral scholar at Arizona State University, where I earned his doctorate in electrical engineering in December 2020. My graduate research focused on MBE growth and characterization of III-V-bismide alloys. Before my graduate studies I worked in industry specializing in analog/mixed-signal circuit design and control systems. In addition to my professional interests, I am an elite level road and gravel cyclist.

Stephen Schaefer work experience
A career timeline built from the work history available for this profile.
Senior Power Design Engineer
Postdoctoral Researcher
CurrentStudied the growth and physical/electrical properties of ultrawide bandgap materials including gallium oxide (Ga2O3) and its alloys by grown by molecular beam epitaxy (MBE). I developed a novel cyclical growth/etch-back MBE methodology that increased experimental throughput by over 6× and single-crystal substrate utilization by over 40×, and demonstrated.
Jul 2022 - Present
Postdoctoral Scholar
Studied the growth and properties of group II-VI and group-IV semiconductor materials for solar cell and infrared photodetector applications. Our research group investigated the MBE growth of bulk CdSe and MgCdTe/CdTe heterostructures for use as the top cell in tandem II-VI/Si solar cells. Additionally, our research group was part of a MURI collaboration.
Dec 2020 - Jul 2022
Graduate Research Associate
Studied the growth and properties of group III-V semiconductor materials for infrared optical applications. Specifically, our group investigated the properties of materials incorporating the atom bismuth (Bi) grown using molecular beam epitaxy (MBE), a high-vacuum technique which allows growth of high-quality single-crystal materials at non-equilibrium.
Aug 2016 - Dec 2020
Electrical Engineer
Participated in a research and development program on permanent-magnet synchronous motors and design of motor controllers. This included design of novel power amplifier circuit topologies and implementation of closed-loop feedback and feedforward control systems. Performed custom electronics circuit and chassis design.
Mar 2014 - Aug 2016
Electrical Engineer
Supported a custom RF plasma power supply design and developed a novel high voltage pulsed plasma power supply prototype.
Aug 2013 - Mar 2014
