Chemical Vapor Deposition Set-up

Chemical vapor deposition (CVD) is a chemical process used to produce high quality, high-performance, solid materials. The process is often used to produced thin film like Graphene, MoS2, WS2, MoSe2, WSe2 on desired substrate. In CVD, the substrate is exposed to one or more  precursors , which react on the substrate surface to produce the desired deposit.

The Fume Hood is often the primary control device for protecting laboratory workers when working with flammable and toxic chemicals. It is a type of local ventilation device that is designed to limit exposure to hazardous or toxic fumes,  vapors  or  dusts .
Centrifuge and Spin Coater

Centrifuge: Centrifuge is a machine with a rapidly rotating container that applies centrifugal force to its contents, typically to separate the denser material (e.g. graphite powder from water mixture) or liquids from solids.
Spin-coater: Spin coater is machine used for coating a material on a substrate by desired rotation speed. Rotation is continued while the fluid spins off the edges of the substrate, until the desired thickness of the film is achieved. The applied solvent is usually volatile, and simultaneously evaporates.
Fluorescence spectrophotometer
Fluorescence spectroscopy  is a type of electromagnetic spectroscopy that analyses fluorescence from a sample. It involves using a beam of xenon lamp, in wavelength range 200nm to 900nm, that excites the electrons in molecules of certain compounds and causes them to emit light. Fluorescence spectroscopy is a rapid, sensitive method for characterizing molecular environments and events.

Thermal Evaporation Deposition System
Thermal evaporation is a common method of physical vapour deposition (PVD). It is one of the simplest forms of PVD and typically uses a resistive heat source to evaporate a solid material in a vacuum environment to form a thin film. The material is heated in a high vacuum chamber until vapour pressure is produced. The evaporated material, or vapour stream, traverses the vacuum chamber with thermal energy and coats the substrate.
Thermal evaporation deposits both metals and non-metals, including aluminium (Al), gold (Au), Silver (Ag), Lithium fluoride (LiF) and Molybdenum oxides (MoO3). Thermal evaporation is used most commonly for applications involving electrical contacts, by depositing such single metals as silver or aluminium. More complex applications include the co-deposition of several components and can be achieved by carefully controlling the temperature of individual crucibles. Thermal evaporation can be applied to deposit metallic contact layers for thin film devices such as OLEDs, solar cells and thin-film transistors. To better achieve consistent, high-quality results, Denton Vacuum controls the rate of deposition using quartz crystal rate sensor, temperature or optical monitoring systems (OMS).

measured as a function of temperature while the substance and reference material are subjected
to a controlled temperature program.
