New Findings on Materials Science from Gunma University Summarized

June 24, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- A new study on Materials Science is now available. According to news reporting originating in Gumma, Japan, by VerticalNews journalists, research stated, "We have studied graphoepitaxy to make nanodots or nanolines ordered along electron beam (EB)-drawn resist guide using block copolymers (BCPs) of polystyrene-polydimethylsiloxane (PS-PDMS)."

The news reporters obtained a quote from the research from Gunma University, "We found out that the number n of ordered molecular dot arrays in the line gap increases stepwise with the gap between guide lines. The n self-assembled dot arrays were ordered in a gap between n and n + 1 times the mean PDMS pitch and self-assembled with no guide pattern."

According to the news reporters, the research concluded: "According to the ordering characteristics, 6 nm sized and 10 nm pitched PDMS dot arrays were formed using the BCP self-assembly with the guide lines."
