Thickness Control of Carbon Film in Vacuum Carbon Coaters

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner width="1/2"][vc_column_text css=""] Precise Thickness Control of Carbon Film in Vacuum Carbon Coaters Control of carbon film thickness deposited on the samples to be analyzed by electron microscopy (SEM, TEM, FE-SEM, and etc.) or Energy-dispersive X-ray spectroscopy (EDX) should be accurate to obtain the best result. The QCM monitoring of the thickness of carbon thin film deposition by resistive evaporation of carbon sources (Rod or Fiber) happens at high temperatures that may cause sensor heating and failure.

These pumps are easy to use and require less care and maintenance than diffusion pumps. The small foot print, the lack of need to cool with water, the speed to reach the desired vacuum, the high purity of these pumps are other advantages compared to diffusion pumps. Using these pumps, the pumping speed can be constant with a good accuracy (One of the disadvantages of these pumps is their high price). Turbomolecular pumps can be used in the range of rough vacuum, high vacuum and Ultra-High Vacuum (UHV) with a constant pumping speed of up to 4000 liters per second.

What is the GLAD Sputtering Technique?

Report, Sputter Coater, Sputtering

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text css=""] What is the GLAD Sputtering Technique? There are various techniques for increasing the quality of thin films deposited by vacuum coating methods. GLAD Sputtering (Glancing Angle Deposition) or OLA (Oblique Angle Deposition) is one of the most widely used techniques in the sputtering deposition process. GLAD method helps to achieve different microstructural architectures and increases the surface area of thin films. In the GLAD Sputtering, you could make an array of periodic microstructures to increase the surface sensitivity.

Plasma Cleaning | What is Plasma Cleaner?

Report

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] What is Plasma Cleaning? Surface cleaning using plasma is an economical way to clean specimens uniformly and securely through plasma treatment. Removal of contaminants from the studied substrates without affecting the overall properties of the material is one of the benefits of the plasma surface cleaning method. Plasma cleaning is widely used in the circuit industry, including cleaning the PCB board before coating and cleaning the lead frames during the packaging process. Plasma sample cleaning has significant advantages over other surface cleaning methods as it applies to a wide range of materials, is eco-friendly, residual-free, and effective in highly sensitive applications like cleaning medical equipment.

Helium Leak Detectors

Report, Vacuum Coating System, Vacuum Pumps

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner width="1/2"][vc_column_text css=""] Mass Spectrometer Leak Detector (MSLD) Helium Leak Detector (HLD), also known as the Mass Spectrometer Leak Detector (MSLD), is an instrument commonly used to find the location of the leakage and measure the rate of it in a system. Among several methods of leak detection, helium leak test is the most accurate one. [/vc_column_text][vc_column_text css=""] What is A Vacuum Chamber Leak? Ideally, the vacuum chamber should retain the vacuum after the pumps have been turned off. But in real systems, over time, system pressure increases. This increase in pressure can be due to the penetration of wall molecules (Outgassing) or due to leakage and penetration of molecules from outside into the system.

Pulsed DC Magnetron Sputtering

Report, Sputter Coater, Sputtering

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] What is Pulsed DC Sputtering? Pulsed DC Magnetron Sputtering is a physical vapor deposition method used to make thin films of various materials including conductors and insulators. It is especially preferable in reactive ion sputtering where the risk of arc discharge damage is high. The arc discharge is a result of charge accumulation on the target and is harmful to both the thin film and the power supply.

[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.…

Enhancement of CoSb3 Thin Film Thermoelectric Properties

Report

[vc_row][vc_column width="1/4"][vc_wp_posts number="10"][/vc_column][vc_column width="3/4"][vc_column_text] CoSb3 Thin Film Thermoelectric (TE) device can directly convert heat to electricity, and vice versa. TE device can work as a solid-state heat pump. Thus can drive to direct conversion of waste heat from for example automobile exhausts to electricity. CoSb3 has been considered as one of the most promising thermoelectric materials in the intermediate temperature range (450-750 ˚K). It’s a semiconductor with narrow band gap and large carrier mobility. Ag doped CoSb3 thin film was investigated by Fan et al. The thin film was grown directly by the effective magnetron sputtering process. Both the electrical conductivity and Seebeck coefficient are greatly enhanced after Ag doping, resulting in the enhancement of power factor.
