چکیده

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 electron microscope ((S)TEM) are extremely challenging. Here, we introduce a concept for a dedicated in-situ (S)TEM with a large sample chamber for flexible multi-stimuli experimental setups and report about the electron optical performance of the instrument.

Off-Axial Aberration Correction using a B-COR for Lorentz and HREM Modes

A dedicated Hitachi HF3300C microscope, “I2TEM”, has recently been installed in CEMES. This microscope has been specially designed to carry on electron interferometry and in-situ TEM experiments. I2TEM is a 300 kV cold FEG microscope fitted with a multibrism set-up, two stages capability, a GIF quantum ER, a 4k X 4k camera and a Cs-corrector “B-COR” from CEOS. The first stage location within th...

Ex-situ studies on calcinations of structural, optical and morphological properties of post-growth nanoparticles CeO2 by HRTEM and SAED

Nanocrystalline particles of Cerium Oxide (CeO2) have been prepared by the chemical precipitation method using Cerium nitrate and Urea with a molar ratio of 1:2. The results revealed that the formation of CeO2 fine particles is influenced by molar ratio of metal nitrates to fuel. Well faceted CeO2 nanoparticles, were synthesized by thermal-assisted dissociation ...

In Situ Biasing of Tapered Si-Ge NW Heterojunctions using Off-Axis Electron Holography

Heterojunction Si-Ge nanowires (NWs) have potential applications such as field effect transistors [1]. Knowledge of the active dopant concentration and distribution, and resultant built-in potential across the Si-Ge p-n junction under biasing conditions is important for improving device performance. Off-axis electron holography is an effective method to measure electrostatic potential with nano...

In Situ Transmission Electron Microscopy of Resistive Switching in Thin Silicon Oxide Layers

Silicon oxide-based resistive switching devices show great potential for applications in nonvolatile random access memories. We expose a device to voltages above hard breakdown and show that hard oxide breakdown results in mixing of the SiOx layer and the TiN lower contact layers. We switch a similar device at sub-breakdown fields in situ in the transmission electron microscope (TEM) using a mo...
