Name: Single Layer WS2 on sapphire substrate


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.

Failed to support desktop PCs with USB 3.2 Gen 2 ports
Does not work with my HP mini PC with USB 3.2 gen 2 ports - when connecting USB portable SSDs to the hub. You won't believe it, but many USB 3.2 Gen 2 hubs only support laptops not desktop PCs (except hubs that have dedicated power supply for higher power USB devices e.g. SSD/HDDs) when connecting USB portable SSDs to the hub. We need a major fix from many of the USB hub vendors so these products can work with desktop PCs that have USB 3.2 Gen 2 ports. Workaround: Just directly connect the USB portable SSD to the PC instead. If you need more USB ports, pick up a good old USB 3.0 hub. They're working correctly with portable USB SSDs when working with desktop PCs. (You'd need a powered USB hub if you're connecting 2 or more portable SSDs - do your own calculation: 5V - 1A per SSD/HDD).

Perfect for ROG Ally X
Want to hook up a keyboard, mouse, headset, AND external display to a ROG Ally X? This will do it and it only takes up one (USB4) port on the Ally X. Oh, and it will also provide enough power to charge the Ally and still have juice for all the other ports. Update: I’ve now tried a few USB4 hubs because I also want Ethernet which this doesn’t have. Unfortunately I’ve discovered that most of them seem to overheat after awhile and I loose connectivity on some of the ports (for whatever reason it’s always the type A ports on the hubs that fail). After letting them cool down, the other USB hubs work again, but it’s still frustrating. This StarTech hub is the only one that works for hours. It’s a little bulkier than other hubs I’ve tried, but that’s probably because it needs to be that way for proper heat dissipation?? Anyway, I wish it had a few more ports (including Ethernet), but for reliability this thing is the best I’ve found.

The Best!
This thing is amazing! Worked right out of the box. No drivers to install, no confusion, just plug and go. I'm using this hub to connect a mouse, a keyboard, and a monitor to my 2025 MacBook Air (M4). Before buying this I bought a complicated, powered hub for 2x the price and wasted multiple hours trying to get the $%^&(*& thing to work, which it never did. If you want to run a display and a few peripherals, this Startech hub is the absolute best bang for your buck.

Quality Control Issues
I want to like this dock, I really do. I purchased it with the intention of using it as a hub for my phone + usb-c external display. The pass-through charging never worked on this dock. Tried multiple cords and tested the dock with nothing plugged into any of the USB ports -- all of the power disappears somewhere onto the hub and the actual charge rate on my phone slows to a trickle. With nothing connected, it estimates >24hrs to charge from 30% to full. The plus side is that the usb ports do work, though the usb-c display went from 100% reliability to <50% within a few months of purchase. Extremely frustrating.

This is the one, buy it for DeX!
Looking for a compact USB hub to connect your laptop or Samsung DeX capable device? Buy this one! I've tried multiple similar items from name brands, and they work fine as a USB and port hub, but this one is able to support power delivery and display data through a single (capable) USB-c cable. I assume because it is noted to be capable of some combo of USB 3.2, PD 3.0 pass through and DP 1.4 alt mode. I'm not quite sure which one(s) make it possible, but it works for an HP Spectre laptop and Galaxy phone. Only improvement suggestion is to add an additional 10gb capable USB-C port in place of the three USB-A ports, but that's being super picky. Thanks StarTech for building another unique solution for connectivity challenges.
