Name: Single Layer WS2 on SiO2/Si


Product Overview

 

The CVD method (chemical vapor deposition) plays an important role in the preparation of disulfide materials, especially for the preparation of two-dimensional layered metal disulfides such as molybdenum disulfide MoS2, tungsten disulfide WS2, etc. When preparing disulfide materials, CVD method utilizes gaseous precursors (such as metal source and sulfur source) to undergo chemical reactions on the heated substrate surface, generating the desired disulfide thin film. According to the type of target disulfide, common metal sources include metal powders, metal halides, etc., while sulfur sources include sulfur powder, hydrogen sulfide, etc.

Two dimensional layered metal dichalcogenides have attracted much attention due to their excellent optoelectronic properties, adjustable bandgap, and excellent air stability. CVD method, as one of the effective methods for preparing such materials, has broad application prospects in fields such as optoelectronic devices, sensors, and energy storage. For example, two-dimensional materials such as molybdenum disulfide and tungsten disulfide have been widely used in fields such as photodetectors, solar cells, and supercapacitors.

Product Features

Large scale preparation: CVD method can prepare large-area and uniform disulfide films, meeting the needs of large-scale applications.

High quality: By optimizing reaction conditions, high-quality and high-purity disulfide films can be prepared with excellent physical and chemical properties.

Controllability: CVD method can accurately control parameters such as film thickness, morphology, and crystal quality, providing the possibility for preparing disulfide materials with specific functions.


Application Fields

 

Transistor: Two dimensional metal disulfide can be used to prepare high-performance transistors due to its unique electronic structure. CVD method can prepare large-area and high-quality thin films to meet the needs of transistor manufacturing.

Sensors: Disulfide materials are also widely used in the field of sensors, such as humidity sensors, gas sensors, etc. The disulfide thin film prepared by CVD method has excellent sensitivity and stability, which can improve the performance of sensors.

Photodetector: Two dimensional metal disulfide is widely used in photodetectors due to its excellent light absorption efficiency and adjustable bandgap

Supercapacitors: Disulfide films prepared by CVD method can provide larger active area and better electron transfer performance, thereby improving the energy density and power density of supercapacitors.

Tissue engineering: CVD technology can prepare materials with high biocompatibility and biological activity, which have potential applications in the field of tissue engineering. For example, disulfide materials can be used to prepare biological scaffolds or coatings, promoting cell growth and tissue repair.

Drug delivery: Disulfide films prepared by CVD method can also be used in drug delivery systems. These films can load drug molecules and control their release rate, achieving precise treatment.

Catalyst: Disulfide films prepared by CVD method have high specific surface area and uniform morphology, which is conducive to the catalytic reaction.

Flexible electronics: With the development of flexible electronics technology, two-dimensional metal dichalcogenides can be used to prepare electrodes or functional layers for flexible electronic devices due to their excellent flexibility and mechanical properties.

These are not sized correctly - beware
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
Edit: I was going to return these pillows but the seller contacted me and offered a full refund due to the size issue without having to send the pillows back. I am happy with this and happy to keep them on a spare queen size bed as they really are nice pillows. Just the wrong size. pros: they are a nice pillow and the cooling feature is really great, and you can adjust to your liking cons: absolutely wrong size. Ordered King, tag says king, all measurements on listing and tag say 20x36, in reality they are more like 20x30. Definitely Queen pillows being sold as King. I did not see any reviews at first about size issues but after I got these and did a search it does look like others have had the same problem. A shame, would have given them a great review if they were the correct size

Really Good Cooling Pillows for Sleeping
Color: Blue-ice Plus, Size: Queen(Pack of 2), Color: Blue-ice Plus, Size: Queen(Pack of 2)
These cooling pillows are very soft and provide excellent support for your head and neck. They are adjustable by taking our the stuffing if you need them to be more flat or less firm. The look great and comes in a pack of two which is a great value. During use, I did notice they have great shape retention and it does not take them long to return to their fluffy full shape. I am a hot sleeper and these do keep your head cool - just be aware using a pillow cover does reduce the cool ability but this allows you to adjust for weather like during winters to add a pillow case for extra warmth. Very happy with this purchase and got a second set to replace my old pillows.

Soft and smooth cover
Color: Grey, Size: Body(20"X 54")
This is a nice pillow cover overall. The fabric feels good and it's comfortable to sleep on, especially compared to a more basic cotton cover. It is maybe a little thinner than I expected, so if you want something thick and heavy this probably isn't that. But for a soft smooth cover that fits and feels decent, I think it's worth it. No major complaints from me after using it.

These are the ones you want
Color: Grey, Size: Body(20"X 54")
May need to iron them out when wash/dried but my old ones still look new- soft, cooling, smooth, color is still great. Not itchy or cheap feeling. Buying a new set for family.
