Post-doctoral Researcher, Semiconductor Materials & Devices
Introduction: The Johns Hopkins University Applied Physics Laboratory (APL), a national leader in scientific research and development, located midway between Baltimore and Washington, DC is seeking a post-doctoral researcher with a strong background in semiconductor materials and devices for solid state energy conversion technologies..
Job Summary: The Research and Exploratory Development Department (REDD) at APL has a strong and growing R&D initiative to pursue innovative solid-state energy technologies in order to support the ever-increasing energy and power demands in both national security and health applications. The technologies that we are developing encompass photovoltaics, thermoelectric devices, and other cutting-edge concepts, where we explore various ‘out-of-the-box’ and game-changing ideas and realize their feasibility through working prototypes in a laboratory. As an example, we are developing a new solar cell materials and devices to extend the endurance of various applications such sensors, unmanned vehicles, and stealth robots. This position will engage in a wide spectrum of R&D including but not limited to fabricating and characterizing organic and inorganic semiconducting materials, testing semiconductor devices, and studying photo-physics and device physics/modeling. The candidate is also expected to perform leading research by developing efficient energy materials and devices based on a solid theoretical foundation and through a hypothesis-driven problem-solving approach. The successful candidate would work and communicate closely and effectively with the materials R&D team to ensure all tasks are performed to extremely high standards.
Duties (Listed in order of importance with the estimated amount of time spent at each task):
1. Work with different PI(s) as a part of team to conduct project(s) in energy converting semiconducting materials and devices, and related applications. Duties include, but are not limited to concept studies, thin-film growth, materials characterization, device fabrication/test/modeling, prototyping, writing reports, and the facilitation, operation, and maintenance of laboratory equipment. (40%)
2. Independently pursue research in semiconductor materials and devices for power and energy technologies (25%)
3. Develop analytical and/or numerical models to explain new ideas and the data from materials, devices, and their applications (15%)
4. Publishing and presenting results in peer reviewed journals and at relevant conferences (15%)
5. Contribute to sponsor briefings and proposals (5%)
