Carbon Coater, Pulsed Laser deposition, Sputter Coater, Thermal evaporation

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Optics are used almost anywhere in the military. From vision systems and target designators used by troops on the ground, through guidance systems utilized in both manned and unmanned aircraft, to reconnaissance and surveillance packages carried by satellites in Earth orbit. These optical systems are usually in a hard and variable temperature and humidity and in contact with abrasive materials such as sand and salt. The use of coatings deposited by different methods of the deposition is a definitive requirement for all these systems. These coatings, in addition to physically protect sensitive components and sensors against stressful conditions, should be such as to allow components and sensors to provide the proper function for which they are designed. Regarding the military status, all these tasks occur when the inappropriate…

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Over the past few decades, technological advances have made it possible to deposition of the thin films under vacuum which referred to as "Hard Coatings". These coatings have different applications due to their special structural and physical properties as protective coatings.

These coatings have many applications in improving tools (such as cutting and forming machines) and machine parts like valves. Properties of a thin film of hard coatings can be classified as follows: Structural characteristics such as…

Perovskite Solar Cells

Carbon Coater, Report, Sputter Coater, Thermal evaporation

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text css=""] Perovskite Solar Cells Perovskite solar cells are a kind of solar cell that combines the structure of perovskite. This substance is often an organic-mineral hybrid of lead or tin halides. Perovskite materials such as methyl ammonium lead iodide are cheap and easy to make. The structure of perovskite is a triple structure of materials, and its general formula is ABO3. This structure consists of octahedrons, in which the cations A are located in octahedral cavities. The thin-film perovskite solar cells have high conversion efficiency and can be manufactured in cheap and cost-effective ways. Compared to silicon solar cells, which are usually made in multi-stage and expensive processes, perovskite solar cells can be constructed easily in laboratory conditions. These cells have been the fastest solar technology ever since.…

Why should an electron microscope sample be prepared?

Carbon Coater, Pulsed Laser deposition, Sputter Coater, Thermal evaporation

[vc_row][vc_column][vc_column_text] Without Sample preparation step With Sample preparation step Scanning Electron Microscope (SEM) is a powerful tool for information on the structure and other nanoscale characteristics of a specimen. This electron microscopy provides nanoscale images which can be used to study various samples, including ceramics, metals, alloys, semiconductors, biological samples, etc. For some specimens, a sample preparation step is required before imaging. This step involves deposition of a 10 nm layer of conductive material such as gold, silver, platinum, or chromium on the sample. High-energy electrons, which collide with the sample during the microscopic process, transfer part of their energy and thus heat up the sample. If the specimen is sensitive to electron beams, such as biological samples, the collision of these beams will damage all or part of the…

CdS/Y/CdS Thin Films

Carbon Coater, Pulsed Laser deposition, Sputter Coater, Thermal evaporation

[vc_row][vc_column width="3/4"][vc_column_text] Optoelectronic devices are electronic components that either produce light or use light in their function. Diode lasers and light emitting diodes (LEDs) are devices that produce light with electrical energy. On the other hand, Solar Cells and photovoltaic cells convert light into electrical energy. Cadmium Sulfide is one of the materials that has been widely considered for use in solar cell technology. The effect of a Yttrium thin film between two thin films of cadmium sulfide (CdS/Y/CdS) has been investigated by researchers to increase the electrical current produced by light absorption. As a result of the use of this compound, an enhancement by ~5 times in the light absorbability and thus enhancement in increasing the photocurrent by ~ 21 times related to the pure CdS thin film is…

Piezoelectric materials are electrically neutral and although the structures of the atoms of these materials are not symmetric, they neutralize each other in terms of electric charge. When a mechanical force is drawn into the piezoelectric material, the distance between the atoms is changed, and they move away from each other or together. As a result, the balance of electrical charges is mixed up and a net positive or negative charge is generated. On the other hand, when an electric current is given to the crystal it starts to oscillate. The frequency of the oscillation is depending on the…

Impact of Bias Voltage on Sputtering and SEM

Carbon Coater, Pulsed Laser deposition, Sputter Coater, Thermal evaporation

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Impact of Bias Voltage on Sputtering and Scanning Electron Microscopy (SEM) The substrate bias voltage is applied to improvement of the directionality and energy of arriving particle to the substrate surface. It can modify the arrival characteristics of these particles such as direction and kinetic energy. As the direction and kinetic energy are controlled, greater penetration into high aspect ratio structures could be reached.
