[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.

Report, Sputter Coater, Thermal evaporation, Thin Film
[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner width="1/2"][vc_column_text css=""] Thin Films Deposition of Organic Materials Electronic components based on thin film organic semiconductors have many applications because of their flexibility and economic large-scale fabrication. These semiconductors allow the creation of electronic devices such as OFET (Organic-Field Effect Transistor), OLED (Organic-Light Emitting Diode), and OPV (Organic Photovoltaic Cell) as a new generation of electronic devices. [/vc_column_text][vc_column_text css=""] What are Organic Materials? Organic molecules are made up of carbon atoms that are able to make strong covalent single, double, or triple bonds with other carbon atoms or atoms like hydrogen (H), oxygen (O), nitrogen (N), and sulfur (S). These compounds are typically classified as polymers or small molecules and can be found in nature or artificially synthesized. The properties, reactions, and production of such structures are studied…

[vc_row][vc_column width="1/4"][vc_row_inner][vc_column_inner][vc_column_text] [lwptoc backgroundColor="#d6d6d6" borderColor="#5b5b5b" skipHeadingText="Recent Posts|References"] [/vc_column_text][/vc_column_inner][/vc_row_inner][vc_wp_posts number="10"][/vc_column][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.

Perovskite Solar Cells

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.…

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.
