Advanced Materials, EarlyView.Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

The Transmission Electron Microscope
1996A typical commercial transmission electron microscope (TEM) costs about $5 for each electron volt (eV) of energy in the beam and, if you add on all available options, it can easily cost up to $10 per eV. As you’ll see, we use beam energies in the range from 100,000 to 400,000 eV, so a TEMis an extremely expensive piece of equipment. Consequently, there

Cathodoluminescence in the scanning transmission electron microscope
Ultramicroscopy, 2017Cathodoluminescence (CL) is a powerful tool for the investigation of optical properties of materials. In recent years, its combination with scanning transmission electron microscopy (STEM) has demonstrated great success in unveiling new physics in the field of plasmonics and quantum emitters.

Applied Surface Science, 2002
Abstract This paper reports the plans and design of positron microscopes being built at KEK (High Energy Accelerator Research Organization), Tsukuba, Japan. A used electron microscope is remodeled. The kinetic energies of positrons produced by accelerators or by nuclear decays do not have a unique value but show a spread over in a wide range ...

Topographical contrast in the transmission electron microscope
Ultramicroscopy, 1975An adaptation of the Foucault method for topographical imaging in the transmission electron microscope is described in detail. The image contrast is produced by selection of electrons which have suffered differential phase retardations in the specimen inner potential.

An environmental cell transmission electron microscope
Review of Scientific Instruments, 1990An aperture-limited, differentially pumped environmental cell has been developed and installed in a JEOL 4000 EX electron microscope. With this environmental cell it is possible to observe, at high spatial resolution, the detailed changes in microstructure that occur during the interaction between a solid and a gaseous environment.
