Aberration-Corrected Electron Microscopy (ACEM) Core

The West Campus ACEM Core, or ACEM, is a university-wide shared user facility that works in partnership with other materials characterization resources at Yale and with the Analytical Services Group at West Campus.

Our core's focus is cutting-edge and high-throughput transmission electron microscopy capabilities. The major instrument (to be installed) is a Thermo Fisher Scientific Spectra Ultra microscope with advanced configurations.

We offer a variety of techniques, including X-ray Spectroscopy (EDS), Electron energy loss spectroscopy (EELS), transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM), electron diffraction (ED), nano beam electron diffraction (NBED), 4D-STEM, convergent beam diffraction (CBED), EELS, EDX, electron holography, in-situ biasing/heating/cooling, CL, holography, Lorentz mode for imaging magnetic materials, i-DPC, and tomography.

Our core will collaborate with other TEM facilities to provide Yale researchers with seamless access for advanced TEM capabilities.

Students interested in getting involved in advanced TEM techniques are welcome to contact Dr. Yang for potential research opportunities.
