A domestic research team developed a technique for synthesizing a two-dimensional semiconductor material thinner than 1 nm (nanometer) and confirmed the potential of using it as a next-generation semiconductor material that surpasses silicon.

The Gwangju Institute of Science and Technology (GIST, President Giseon Kim) announced on the thirteenth that the Chemistry Professor Hyunseop Lim’s research team improved the synthesis means of two-dimensional molybdenum disulfide (MoS2) and developed a large-area single crystal synthesis method that dramatically reduces the boundaries between crystal particles.

Molybdenum disulfide is attracting attention as a next-generation two-dimensional nanomaterial because it might probably overcome the restrictions of graphene, which is named a dream material. It was lacking.

The research team improved synthesis efficiency by replacing the present solid precursor utilized in the synthesis of two-dimensional molybdenum disulfide with an inorganic molecular precursor. A latest technology has been developed that may synthesize two-dimensional molybdenum disulfide as a single layer and single crystal on a sapphire substrate.

As well as, the role of the terminal functional group of the sapphire substrate, which had been shrouded in a veil, was identified in ‘epitaxial growth’, a key strategy of single crystal synthesis. A sapphire substrate composed of aluminum and oxygen could have a hydroxyl group or an aluminum group as a terminal functional group depending on the air temperature.

Amongst these, a latest mechanism that the aluminum terminal functional group plays a key role in the expansion of two-dimensional molybdenum disulfide single crystals was proposed through surface crystal structure evaluation and quantum calculations.

Professor Lim Hyun-seop said, “We expect that this research will advance the timing of using molybdenum disulfide, a two-dimensional semiconductor nanomaterial, as a next-generation semiconductor material.” It can also contribute to development,” he said.

  1. Hey there! Would you mind if I share your blog with my
    twitter group? There’s a lot of people that
    I think would really appreciate your content. Please let
    me know. Thank you

  2. I don’t even know how I finished up here, however I assumed this put up used to be great.
    I do not understand who you’re but definitely you are going to
    a famous blogger if you aren’t already. Cheers!

  3. I do not even know how I stopped up right here, but I assumed this submit used to be good.
    I do not understand who you are however certainly
    you’re going to a famous blogger if you aren’t already. Cheers!

  4. My partner and I stumbled over here different page and thought
    I may as well check things out. I like what I see so now i
    am following you. Look forward to checking out your web page yet again.

  5. Hey I know this is off topіc but I was wondering if you
    knew of any widgets I could add tto my blog that automaticalⅼy tweet my newest tᴡitteг updates.
    I’ve been looking for a plᥙɡ-in like this for quite some time and was һoping mаyƅe you would have some experience wіth something like thіs.
    Please let me know if you run into anything. I truⅼy enjoy
    reaing your blog and I look forward to your new updates.

  6. Thank you a lot for sharing this with all folks you actually realize what you are speaking approximately! Bookmarked. Please additionally consult with my web site =). We may have a link trade contract between us|

  7. It’s actually a nice and helpful piece of info. I am glad that you shared this helpful information with us. Please stay us informed like this. Thank you for sharing.|

  8. Hey there this is kinda of off topic but I was wanting to know if blogs use WYSIWYG editors or if you have to manually code with HTML. I’m starting a blog soon but have no coding knowledge so I wanted to get guidance from someone with experience. Any help would be greatly appreciated!|

  9. Hello! I know this is kinda off topic however I’d figured I’d ask. Would you be interested in exchanging links or maybe guest writing a blog article or vice-versa? My website covers a lot of the same subjects as yours and I feel we could greatly benefit from each other. If you might be interested feel free to shoot me an email. I look forward to hearing from you! Terrific blog by the way!|

  10. I was wondering if you ever thought of changing
    the page layout of your blog? Its very well written; I love what youve got to
    say. But maybe you could a little more in the way of content so people could connect with it better.
    Youve got an awful lot of text for only having 1 or two pictures.
    Maybe you could space it out better?

  11. I have been browsing online more than 3 hours today, yet I never found any interesting article like yours. It is pretty worth enough for me. Personally, if all web owners and bloggers made good content as you did, the internet will be much more useful than ever before.|

  12. Hi there! I understand this is somewhat off-topic but I needed to ask. Does running a well-established blog like yours take a lot of work? I’m brand new to blogging but I do write in my diary daily. I’d like to start a blog so I can share my own experience and feelings online. Please let me know if you have any kind of ideas or tips for brand new aspiring bloggers. Thankyou!|

  13. I am not sure where you are getting your information, but great topic.

    I needs to spend some time learning much more or understanding more.
    Thanks for excellent information I was looking for this information for my mission.

  14. Hey There. I found your weblog the usage of msn. This is a really smartly written article. I will make sure to bookmark it and come back to read more of your helpful info. Thank you for the post. I’ll certainly return.|

  15. You can certainly see your enthusiasm within the article you write. The arena hopes for even more passionate writers like you who are not afraid to mention how they believe. All the time go after your heart.|

  16. Its like you read my mind! You seem to know so much about this, like you wrote the book in it or something. I think that you can do with a few pics to drive the message home a bit, but other than that, this is magnificent blog. An excellent read. I will definitely be back.|

  17. I blog frequently and I truly appreciate your information. The article has really peaked my interest. I’m going to take a note of your site and keep checking for new information about once a week. I subscribed to your Feed too.|

Can somebody else please provide feedback and let me know if this is happening to them too? This might be a issue with my browser because I’ve had this happen previously. Appreciate it|

  19. Hi there! This is kind of off topic but I need some advice from an established blog. Is it hard to set up your own blog? I’m not very techincal but I can figure things out pretty fast. I’m thinking about setting up my own but I’m not sure where to start. Do you have any points or suggestions? Cheers|

  20. These are actually enormous ideas in concerning blogging. You have touched some fastidious things here. Any way keep up wrinting.|
