Reports Summarize Nanowires Findings from Indian Institute of Technology

June 27, 2014

By a News Reporter-Staff News Editor at Science Letter -- Research findings on Nanowires are discussed in a new report. According to news reporting out of Uttarakhand, India, by NewsRx editors, research stated, "We report a study on the growth temperature dependent phase formation and its magnetic property in Mn-doped Ge nanowires (NWs) fabricated at temperature (T-G) varying from 600 to 900 degrees C using vapor-liquid-solid technique."

Our news journalists obtained a quote from the research from the Indian Institute of Technology, "Structural and magnetic measurements on the nanowires reveal that Mn are not homogeneously distributed in Ge-matrix, but atomic clusters (Mn-rich regions) are formed in lightly doped Ge matrix (GeMn-matrix) at 600 degrees C. Upon increasing T-G, Ge3Mn5 compound starts to nucleate in expense of atomic clusters following the migration of Mn from GeMn-matrix."

According to the news editors, the research concluded: "At 900 degrees C, only precipitates of Ge3Mn5 in cluster-free Ge-matrix are found."
