material property data, as defined by a pre-determined constitutive model, using inverse methods. Microstructural characterization using SEM, TEM, x-ray, and neutron scattering is applied when appropriate
-
nanoelectronics fabrication methods. Measurements are performed in diagnostic-compatible CVD and ALD reactors under realistic deposition conditions. Various in situ vibrational spectroscopic techniques are employed
-
. Nondestructive methods such as Prompt Gamma Activation Analysis (PGAA) are well suited for multi-elemental analysis for bulk materials. The research will explore imaging of gamma ray emission by Compton scattering
