Russian researchers obtain atomically thin molybdenum disulfide (2D) films on large-area substrates by ALD

[Press release: LINK] Researchers from the Moscow Institute of Physics and Technology have managed to grow atomically thin films of molybdenum disulfide spanning up to several tens of square centimeters. It was demonstrated that the material’s structure can be modified by varying the synthesis temperature. The films, which are of interest to electronics and optoelectronics, were obtained at 900-1,000 degrees Celsius. The findings were published in the journal ACS Applied Nano Materials.

Two-dimensional materials are attracting considerable interest due to their unique properties stemming from their structure and quantum mechanical restrictions. The family of 2D materials includes metals, semimetals, semiconductors, and insulators. Graphene, which is perhaps the most famous 2D material, is a monolayer of carbon atoms. It has the highest charge-carrier mobility recorded to date. However, graphene has no band gap under standard conditions, and that limits its applications.

A great start for the BALD Blog in 2016 and welcome to all Russian ALD Visitors!

2016 has started of fantastic on the blog with a lot of new visitors - let´s hope it was not based on New Years resolutions since those tend to fade away. Since May 2015 there has been a monthly average of about 10,000 visitors / month but now suddenly there is an influx of visitors that would extrapolate to >15,000 visitors/month if it goes on for another two weeks!

Looking at the statistics it seems that quite many of the new visitors are originating out of Russia and it could be that Russia for the first time reach the same share of visitors as USA who has always been the most common origin for the the blog traffic.

Guest Blog: ALD Russia 2015 workshop: travel notes by Riikka P...

Below you find my travel report from the ALD Russia workshop in Dolgoprudny, Moscow region, September 2015. Originally, this travel report was published as a stand-along text through Google docs and also through through BALD Engineering blog

After the ALD Russia workshop, this ALD History blog has been created, and one travel report published in it (St. Petersburg, 2015, Puurunen). Since the ALD Russia workshop was historical in nature in many ways, and since it will be wise to collect ALD-history-related travel reports in one place, I want to publish the travel report here again. To this version, I have added a significant number of previously unpublished photographic material.

ALD History Blog: Travel notes, St Petersburg, November 2015, by Rii...: I had the pleasure of visiting St. Petersburg in November 2015. This was my second visit to St. Petersburg related to ALD; the first was in ...
