(S)TEM (Scanning Transmission Electron Microscopy)

(S)TEM (Scanning Transmission Electron Microscopy)

Elemental analysis, state evaluation, particle size analysis, and acquisition of three-dimensional structural images at the nanoscale.

TEM (Transmission Electron Microscopy) is a method that involves irradiating a thin sample with an electron beam, imaging the electrons that have passed through or scattered from the sample, and observing it at high magnification. ■ Advantages - Enlarged images can be obtained with sub-nanometer spatial resolution, allowing for the observation and analysis of the sample's fine structure and lattice defects. - It is possible to evaluate the crystallinity of the sample and identify materials. - By fabricating samples using FIB (Focused Ion Beam), it is possible to observe specific locations within a device with pinpoint accuracy. - By combining optional features, it is also possible to analyze the composition and state of localized areas. ■ Disadvantages - It is necessary to thin the sample (in some cases, thinning may be difficult for certain samples). - It does not observe individual atoms but rather displays average information in the thickness direction of the sample (typically about 0.1 μm thick). - Sample processing and observation may lead to alteration or deformation of the sample.

[Analysis Case] Observation of Heterojunction Interface in CIGS Thin-Film Solar Cells

[Analysis Case] Observation of Heterojunction Interface in CIGS Thin-Film Solar Cells

Evaluation of the crystal structure of the high-resistance layer at the CdS/CIGS junction interface using ultra-high-resolution STEM.

We directly observed the CdS/CIGS heterojunction interface using a Cs-corrected STEM device. TEM images, high-resolution HAADF-STEM images, and simulations using first-principles calculations confirmed that CIGS and CdS are heteroepitaxially joined.

[Analysis Case] Evaluation of Si Anode in Lithium-ion Secondary Batteries

[Analysis Case] Evaluation of Si Anode in Lithium-ion Secondary Batteries

It is possible to evaluate the state of the electrodes before and after charging, as well as the presence and distribution of Li.

Silicon (Si) is one of the candidates for high-capacity anode active materials, but it is said to suffer from severe cycle degradation due to the very large volume changes during charge and discharge. We dismantled and observed the Si anode before and after charging under controlled atmospheric conditions. Furthermore, we created cross-sectional observation samples using the FIB micro-sampling method and conducted shape observation and EELS measurements with a Cs-corrected STEM device to evaluate the condition of the Si electrode and the distribution of Li within the electrode.

[Analysis Case] TEM Analysis under Atmosphere Control and Cooling (B0156)

[Analysis Case] TEM Analysis under Atmosphere Control and Cooling (B0156)

Observation with a high-resolution SEM equipped with FIB without atmospheric exposure (controlled atmosphere)!

Our organization has established a system that suppresses atmospheric exposure through atmosphere control, and further cools the samples for processing, observation, and analysis. We can produce TEM thin samples while maintaining the original structure of the specimen, allowing for observation and analysis. Even with unstable materials, we can perform thinning processing while cooling, and by maintaining a vacuum during the transfer between processing and observation devices, we enable cross-sectional TEM/SEM observation that minimizes atmospheric exposure and thermal alteration. 【Measurement and Processing Methods】 ■ [(S)TEM] Scanning Transmission Electron Microscopy ■ Processing under atmosphere control ■ Cryo-processing *For more details, please download the PDF or feel free to contact us.

[Analysis Case] (S)TEM Observation by Negative Staining

[Analysis Case] (S)TEM Observation by Negative Staining

Examples of morphological observation of liposomes, CNF, microparticles, proteins, etc.!

Our organization offers (S)TEM observation using negative staining. Organic functional materials, such as fine particles and fibrous substances, are primarily composed of light elements like C (carbon), H (hydrogen), O (oxygen), and N (nitrogen), which do not provide sufficient contrast for morphological observation in (S)TEM. Therefore, by applying staining to these materials, we can enhance the contrast and enable observation. In this instance, we will introduce a case where negative staining was performed using phosphotungstic acid (H3[P(W3O10)4]·nH2O, abbreviated as PTA). 【Measurement Method / Processing Method】 ■ [(S)TEM] Scanning Transmission Electron Microscopy ■ Others *For more details, please download the PDF or feel free to contact us.

[Analysis Case] (S)TEM Observation of Polymer Materials Using Electronic Staining

[Analysis Case] (S)TEM Observation of Polymer Materials Using Electronic Staining

We will introduce examples of observing polymer materials using SEM-STEM and (S)TEM!

Our organization offers (S)TEM observation of polymer materials using electron staining. Since polymer materials are composed of light elements, it is difficult to obtain clear contrast in (S)TEM observations. Staining can enhance the contrast for such materials. This document introduces examples of staining and observation using a method called electron staining with ruthenium tetroxide (RuO4), osmium tetroxide (OsO4), and phosphotungstic acid (H3[P(W3O10)4]·xH2O, abbreviated as PTA).

[Analysis Case] Fine Structure of Hair Cross-Section (S)TEM Analysis

We will introduce examples of observations of hair cell membrane complexes (CMC)!

Our organization offers (S)TEM analysis of the fine structure of hair cross-sections. The hair cell membrane complex (CMC) serves as a pathway for chemicals during processes such as bleaching and dyeing hair. In particular, the CMC between the cuticle layers has a three-layer structure, which we have visualized. We present a case where osmium tetroxide (OsO4) was used for electron staining targeting unsaturated fatty acids in lipids, followed by TEM observation and STEM-EDX analysis. [Measurement and Processing Methods] ■ [(S)TEM] Scanning Transmission Electron Microscopy ■ [TEM-EDX] Energy Dispersive X-ray Spectroscopy (TEM) ■ Ultramicrotome processing ■ Others *For more details, please download the PDF or feel free to contact us.
