Full Optical Properties of Carbonaceous Aerosols by High Energy Monochromated Electron Energy-loss Spectroscopy

Nanoscale mapping of optical band gaps using monochromated electron energy loss spectroscopy.

Using monochromated electron energy loss spectroscopy in a probe-corrected scanning transmission electron microscope we demonstrate band gap mapping in ZnO/ZnCdO thin films with a spatial resolution below 10 nm and spectral precision of 20 meV.

High-resolution monochromated electron energy-loss spectroscopy of organic photovoltaic materials.

Advances in electron monochromator technology are providing opportunities for high energy resolution (10 - 200meV) electron energy-loss spectroscopy (EELS) to be performed in the scanning transmission electron microscope (STEM). The energy-loss near-edge structure in core-loss spectroscopy is often limited by core-hole lifetimes rather than the energy spread of the incident illumination. Howeve...

Monochromated Electron Energy-Loss Spectroscopy Spectrum Imaging of Organic Photovoltaic Devices

Bulk heterojunction (BHJ) organic photovoltaic (OPV) based solar cells hold the promise of achieving the highly desirable objective of low cost, clean renewable electrical power via solar energy collection in a flexible device architecture. A very active OPV research and development effort is being driven by the potential to produce large active areas on flexible substrates at low cost and high...
