Staff Scientist, NCEM
Peter Ercius graduated from Cornell University with a B.S. in applied and engineering physics in 2003. He remained at Cornell and completed a Ph.D. in applied and engineering physics with Professor David A. Muller in 2009. His dissertation project focused on three-dimensional (3D) electron tomography of semiconductor devices using scanning transmission electron microscopy (STEM). He then joined the NCEM facility as a collaborative postdoctoral researcher for 2 years before being hired as a permanent Staff Scientist of the Molecular Foundry. Peter is currently in charge of the electron tomography program at NCEM and the dual aberration-corrected TEAM 0.5. Dr. Ercius is a leading expert in electron tomography and collaborates with users of the Molecular Foundry on a wide range of projects including S/TEM atomic resolution imaging, electron tomography, 4D-STEM scanning diffraction, in situ liquid TEM, and electron energy loss spectroscopy (EELS).
Dr. Ercius utilizes the atomic resolution imaging capabilities of the TEAM I and TEAM 0.5 transmission electron microscopes for atomic resolution imaging and analysis of many nanoscale materials. He is a leading expert in 3D imaging and analysis of nanostructures with a focus on the application of electron lens aberration correction. He utilizes the TEAM microscopes and TEAM Stage at the NCEM facility to image nanoscale objects in 3D at atomic resolution. He also utilizes the high-resolution imaging capabilities coupled with liquid cells and direct electron detectors to study materials processes in liquid environments. His broad range of research interests include:
- 3D nanoscale and atomic electron tomography (AET)
- STEM and TEM aberration correction
- Atomic scale materials characterization
- In situ liquid TEM
- Electron energy loss spectroscopy (EELS)
