The EXtreme Environment Microsystems Laboratory (XLab) is a part of the Aero/Astro Department at Stanford University. We are focused on the development of micro- and nano-systems for operation within extreme harsh environments. Researchers in the XLab are investigating the synthesis of temperature tolerant, chemically resistant and radiation-hardened wide bandgap semiconductor thin films and nanostructures. These new material sets serve as a platform for the realization of sensor, actuator and electronic components that can operate and collect data under the most hostile conditions. More specifically, smart and adaptable structures for extreme environments are enabled through the technology developed in the XLab. Our research efforts support a variety of applications including deep space systems, hypersonic aircraft, combustion monitoring and subsurface monitoring.
