[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text css=""] The Best Conductive Coating Thickness for Electron Microscopy and Microanalysis Coating an insulating specimen with a thin conductive layer is one of the common sample preparation steps prior to the surface analysis techniques engaging electrons. A thin coating of a conductive material with proper grain size enhances charge dissipation on the sample surface that is bombarded by the electrons. Choosing the proper conductive coating thickness for electron microscopy and microanalysis, such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), electron backscatter diffraction (EBSD), energy-dispersive X-ray spectroscopy (EDS/EDX), and wavelength-dispersive spectroscopy (WDS), helps to achieve a high-resolution imaging and precise examination of the sample’s surface.

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner width="1/2"][vc_column_text css=""] Bias Sputtering Bias sputtering, or substrate biasing, involves applying an electric voltage to the substrate, which increases the ion bombardment of the substrate and the subsequent coating during the sputter deposition process. The main aim of substrate bias sputtering is to minimise film contamination by the process gas atoms, and it helps produce more condensed films with lower electrical resistivity compared to those formed without substrate biasing.

During the sputtering process, the surface of the sputtering target is bombarded by the positive ions generated in the plasma of the process gas. The substrate ion bombardment can be controlled by adjusting the applied voltage, which can modify the…

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text css=""] What Is DC Sputtering? Direct Current sputtering, also known as DC sputtering, a subclass of diode sputtering, is a common method used to deposit thin films of conductive materials. Applying a DC voltage between the cathode and anode in a vacuum chamber results in the formation of energetic plasma ions, bombarding the target material on the cathode and ejecting its atoms, which are then deposited on the substrate.

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text css=""] Transmission Electron Microscopy (TEM) Conventional transmission electron microscopy (TEM) utilises a beam of electrons interacting with a thin specimen. The scattered electrons transmitted through the sample are subsequently collected to form an image revealing its structure. Transmission electron microscopes are consistently developed to overcome challenges and enhance the image resolution below 1 nm and magnification of up to 1,000,000x, creating various modes for extensive applications, such as high-resolution imaging of micro-nano structures, crystalline phase orientations, and elemental analysis. Moreover, achieving high-quality, accurate results for electron microscopy, specifically TEM, requires considerations in sample preparation steps prior to the analysis. This article is intended to shed light on the transmission electron microscopy basics, components, modes, as well as its applications, advantages, and challenges.

Magnetron sputtering is a subcategory of sputtering deposition in which a magnetron cathode is used to enhance ion-target collisions, thereby intensifying the sputtering and deposition rates. The merits of magnetron sputter deposition over conventional sputter deposition have made magnetron cathodes a vital part of a typical sputtering system.

Optoelectronics include electronic components related to optics (light), in which the light is emitted, modified, or converted, and are activated or deactivated based on the intensity of light. These devices contain various parts like emitters and photodetectors, including photodiodes and phototransistors, which are significantly reliant on high-quality thin film deposition of metals and semiconductors.
