Polycrystalline Pb1-xSnxTe (0.0 ≤x ≤1.0) telluride alloys were synthesized by the direct fusion technique. Thin films of these materials were prepared by a hot wall deposition method on glass substrates at Tsub =230–330 °C and in a vacuum of about 10-5 Torr. The microstructure of the films was characterized by XRD, SEM, EDX and AES. The films showed a natural cubic structure. The thin films’ microstructure consisted of densely packed grains with dimensions of 50–300 nm and crystallite growth direction is perpendicular to substrate plane. The asgrown Pb1-xSnxTe films showed p-type conductivity. Thermoelectric measurements of the films showed high values for the room-temperature Seebeck coefficient ranging, from 20 to 400 μV·K-1, for SnTe to PbTe thin films, respectively. The conductivity of the films was in the range of 3·101–1·104 Ω-1·cm-1.

Hello! Someone in my Myspace group shared this site with us so I came to take a look. I’m definitely enjoying the information. I’m bookmarking and will be tweeting this to my followers! Terrific blog and fantastic design and style.
The next time I read a blog, I hope that it doesnt disappoint me as much as this one. I mean, I know it was my choice to read, but I actually thought youd have something interesting to say. All I hear is a bunch of whining about something that you could fix if you werent too busy looking for attention.
I am really enjoying the theme/design of your site. Do you ever run into any web browser compatibility problems? A few of my blog audience have complained about my site not operating correctly in Explorer but looks great in Safari. Do you have any suggestions to help fix this problem?
Thanks for every other excellent article. The place else may anyone get that type of info in such a perfect way of writing? I’ve a presentation next week, and I am at the look for such info.
It is really a great and useful piece of information. I’m glad that you shared this useful info with us. Please keep us informed like this. Thank you for sharing.
Thanks for one’s marvelous posting! I certainly enjoyed reading it, you can be a great author.I will ensure that I bookmark your blog and will come back later in life. I want to encourage you continue your great writing, have a nice afternoon!
Lovely site! I am loving it!! Will be back later to read some more. I am taking your feeds also.
This blog is definitely rather handy since I’m at the moment creating an internet floral website – although I am only starting out therefore it’s really fairly small, nothing like this site. Can link to a few of the posts here as they are quite. Thanks much. Zoey Olsen
Heya! I’m at work surfing around your blog from my new iphone 4! Just wanted to say I love reading your blog and look forward to all your posts! Carry on the superb work!
An interesting discussion is worth comment. I think that you should write more on this topic, it might not be a taboo subject but generally people are not enough to speak on such topics. To the next. Cheers
Some times its a pain in the ass to read what blog owners wrote but this internet site is really user friendly! .
Some really interesting details you have written.Assisted me a lot, just what I was looking for : D.
You have brought up a very superb points, regards for the post.
I have recently started a site, the information you offer on this web site has helped me greatly. Thank you for all of your time & work.
I’ve been browsing online more than three hours lately, but I by no means discovered any attention-grabbing article like yours. It’s pretty price enough for me. Personally, if all website owners and bloggers made just right content as you did, the web will likely be much more useful than ever before.
