[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Co-Deposition Techniques in Vac Coat Coaters After the scientific revolution driven by nanotechnology, nanocomposites, and hybrid materials with many applications play a vital role in modern science and technology research. These kinds of materials offer electrical and mechanical properties, optical interaction, and thermal conductivity with very high efficiency. The vital part of nanocomposites research is choosing the best way to prepare these complex materials. Co-Deposition Techniques indicates a procedure with two, three, or more deposition sources. Thus, these different or same sources react together and coat on the desired samples to provide alloys and hybrids with excellent characteristics.

Upgrading the Sample Planetary Rotation System

Sputtering, Sputter Coater, Thermal evaporation, Thin Film

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Upgrading the Sample Planetary Rotation System One of the characteristics of a suitable thin film is the degree of uniformity of the deposited layer. Rotation of the substrate during coating is one of the most effective ways to increase the uniformity of thin film deposited in the Physical Vapor Deposition (PVD) method. The effectiveness of substrate rotation in improving the uniformity of the deposited thin film depends on the geometry of the substrate and how it rotates during the coating process. For example, in the case of substrates with a flat geometric shape (such as a disk), rotation about an axis perpendicular to the surface of the substrate is sufficient to create a uniform layer on it.

Deposition, Pulsed Laser deposition, Sputtering, Thermal evaporation, Vacuum Deposition Method

[vc_row][vc_column width="3/4"][vc_column_text] Deposition Deposition is a set of processes used to create thin or thick layers of a substance atom-by-atom or molecule by molecule on a solid surface. The created layer deposits as a coating on a surface and changes the properties of the substrate surface depending on the application. The thickness of the deposited layers in this process, depending on the coating method and the type of material, can be in the range of one atom (nanometer) to several millimeters. [/vc_column_text][vc_separator][vc_row_inner][vc_column_inner][vc_column_text] There are several methods for creating a layer of different materials on different surfaces such as spraying, spin coating, plating and vacuum deposition methods that are performed from the vapor phase of the target material. In the following, we will introduce some deposition methods: [/vc_column_text][/vc_column_inner][/vc_row_inner][vc_row_inner][vc_column_inner][vc_single_image image="6379" img_size="large" add_caption="yes"…

In this method, the target material is placed inside thermal sources. These thermal sources are normally in form of Boat, Basket or Coil. The materials to be deposited are heated up, melted and evaporated by passing a high electric current through the terminal of evaporation sources. The vapor generated from the target material moves to the substrate and is deposited as a thin film with a thickness of a few nanometers to a few micrometers. Boats or baskets are made of refractory metals such as tungsten, molybdenum or tantalum. Thermal…

Feedthroughs include one or more conductor pins that pass through a vacuum flange that is well sealed against air leakage. The conductive pins are electrically separated from the flange by insulation. These insulators, which are mostly made of ceramic, usually tolerate a significant difference pressure along their length. All of the vacuum coating systems fabricated by VacCoat Ltd. are also equipped with electrical feedthroughs. In DTT thermal evaporation deposition systems, the high current electrical feedthroughs are used and passed electric current more than 100A through them. Passing this high current can be caused…

Chalcogenide Thin Films Deposition

Pulsed Laser deposition, Sputter Coater, Thermal evaporation

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Chalcogenide Thin Films Deposition Chalcogenides are materials that contain at least one of the chalcogen elements, the substances of group 16 of the periodic table (sulfur, selenium, tellurium, etc.). Chalcogenic glass has received a lot of attention due to its special optical properties, such as high refractive index, infrared (IR) transparency, nonlinear optical properties, and reversible phase change from amorphous to crystalline. Photovoltaic cells are one of the applications of chalcogenide thin films. Optical properties and other characteristics of thin films (thermal, mechanical, resistance, chemical, photo-sensitivity, etc.) are highly dependent on the deposition methods. Depending on how the thin film is deposited, the stoichiometry, structure, defect stats, and many other features can be controlled.

Deposition of the Highly Reactive Materials

Thermal evaporation

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Deposition of the highly reactive materials There are materials with a high affinity to oxygen among the materials which are deposited by the vacuum coating systems. If these substances are in the vicinity of a small amount of oxygen, they react quickly and burn completely. Lithium is easily oxidized when exposed to air. On the other hand, this alkali metal and its compounds have many applications in the industry. For example, this metal is used to produce rechargeable batteries that are used in smartphones, tablets, etc. The best way to lithium deposition is the thermal evaporation method.

In this method, the high-power pulsed laser beam focuses on the target that is inside the vacuum chamber. The target material is vaporized by a laser beam in the form of a Plasma Plume and deposit on the substrate as a thin film. This process can be performed in a high vacuum environment or in an environment with background gases such as oxygen. Oxygen is usually used for the oxide deposition to completely oxygenate the deposited thin film during the pulsed laser deposition (PLD) process. Figure 1 shows the PLD mechanism of operation.
