Prospects for quantitative and time-resolved double and continuous exposure off-axis electron holography.
The technique of double exposure electron holography, which is based on the superposition of two off-axis electron holograms, was originally introduced before the availability of digital image processing to allow differences between electron-optical phases encoded in two electron holograms to be visualised directly without the need for holographic reconstruction. Here, we review the original me...
متن کاملTowards quantitative electrostatic potential mapping of working semiconductor devices using off-axis electron holography.
Pronounced improvements in the understanding of semiconductor device performance are expected if electrostatic potential distributions can be measured quantitatively and reliably under working conditions with sufficient sensitivity and spatial resolution. Here, we employ off-axis electron holography to characterize an electrically-biased Si p-n junction by measuring its electrostatic potential,...
متن کاملSix-pack off-axis holography.
We present a new holographic concept, named six-pack holography (6PH), in which we compress six off-axis holograms into a single multiplexed off-axis hologram without loss of magnification or resolution. The multiplexed hologram contains straight off-axis fringes with six different orientations, and can be generated optically or digitally. We show that since the six different complex wavefronts...
متن کاملHybridization approach to in-line and off-axis (electron) holography for superior resolution and phase sensitivity
Holography--originally developed for correcting spherical aberration in transmission electron microscopes--is now used in a wide range of disciplines that involve the propagation of waves, including light optics, electron microscopy, acoustics and seismology. In electron microscopy, the two primary modes of holography are Gabor's original in-line setup and an off-axis approach that was develope...
متن کاملA Dedicated In-situ Off-axis Electron Holography (S)TEM: Concept and Electron-Optical Performance
The progress in (scanning) transmission electron microscopy has led to an unprecedented knowledge of the microscopic structure of functional materials at the atomic level. Additionally, although not widely used yet, electron holography is capable to map the electric and magnetic potential distributions at the sub-nanometer scale. Nevertheless, in-situ studies inside a (scanning) transmission el...
