Thin Films Coating and Applications

Report

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] What is Thin Film and its Properties? A thin film is a layer of material with a thickness in the range of a nanometer to a few micrometers. Many industries make use of different deposition methods to create thin films. Thin films are widely used in our everyday life, such as the metal coated glass used as mirror in every home. Vac Coat as a manufacturer and designer of Vacuum Coating Systems, uses Physical Vapor Deposition (PVD) methods, such as sputtering, thermal evaporation, and pulsed laser deposition (PLD), to create different types of them.

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] An Overview of Sputtering Sputtering in physics is called to the process in which a plasma of high energy particles/ions knock out the species on the surface layer of a solid target. This phenomenon naturally happens in the outer space, constantly forming the universe and causes spacecraft’s corrosion. Here, on Earth, the science and industry make use of sputtering process to generate or eradicate thin films of nano/micrometer thickness for various applications in optics, electronics, etc. [/vc_column_text][/vc_column_inner][/vc_row_inner][vc_row_inner css=".vc_custom_1706972218695{background-color: #d9d9d9 !important;}"][vc_column_inner width="1/2"][vc_raw_html]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[/vc_raw_html][vc_btn title="Desk Sputter Coater – DSR1" style="3d" color="juicy-pink" align="center" css=".vc_custom_1703590839097{margin-top: -20px !important;}" link="url:https%3A%2F%2Fvaccoat.com%2Fproducts%2Fdesk-sputter-coater-dsr1%2F|title:Desk%20Sputter%20Coater%20%E2%80%93%20DSR1|target:_blank"][/vc_column_inner][vc_column_inner width="1/2"][vc_cta h2="" txt_align="center" style="3d" color="mulled-wine" add_button="bottom" btn_title="Thin Films" btn_style="3d" btn_color="juicy-pink" btn_align="center" btn_link="url:https%3A%2F%2Fvaccoat.com%2Fblog%2Fthin-film-and-thin-films-types%2F|title:Thin%20Films%20Coating%20and%20Applications|target:_blank"][/vc_cta][/vc_column_inner][/vc_row_inner][vc_row_inner][vc_column_inner width="1/2"][vc_column_text] What is Sputtering?

Sample Preparation for Scanning Electron Microscopy

Report

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] What is the Purpose of Sample Preparation? Samples to be investigated by electron microscopy need preparation through various techniques to obtain the most accurate results. The sample preparation procedure may include steps such as washing, drying, fixation, mounting, and coating to achieve the best result. Not carrying out preparation steps before imaging may deteriorate the device's performance, image quality, and sample structure.

Scanning Electron Microscope (SEM)

Report

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] What is Scanning Electron Microscopy? Scanning electron microscopy is an efficient and non-destructive technique that provides detailed information on the morphology, composition, and structure of the studied materials. The first one of this electron microscope was invented in 1942. It was shown at that time that Secondary Electrons (SE) produced topographic contrast using the collector positive bias rather than the sample. After that, many changes were made until the first commercial sample of scanning electron microscope was introduced in 1965.

What is Plasma?

Report

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text css=""] Plasma Physics Plasma is the fourth state of matter that can be reached in high energies. Normally, when atoms in a solid gain enough energy it goes to liquid phase, and then the phase transition is continued to the gas phase at higher energy levels, and then plasma is formed at extremely high temperatures. In a typical plasma, some or all of the electrons in an atom gain enough energy to overcome nucleus potential barrier and an ionized gas is formed. So, plasma contains free electron-ions and is able to conduct electricity. Since atoms are normally neutral, the plasma is electrically neutral. Plasma may contain magnetic fields as moving electric charges create them.

Electron Microscope Invention: A Historical Overview

Report

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] History of Electron Microscope (1930-1980) Nowadays, the electron microscope is an essential instrument to characterize new structures and materials and electron microscope invention has become a popular topic for scientific research. In a typical electron microscope a beam of electrons is focused upon a target specimen. Information is often gathered from electrons transmitted through or scattered from the specimen by Bragg diffraction, alongside data gathered from Auger electrons, characteristic x-rays, and the charge absorbed by the specimen. On the basis of particle-wave duality theory of de Broglie, electrons can replace photons in a microscope to improve the image resolution more than 5000 times.
