  • Synthesis of silicon nanorods
    Patent number: 8858707
    Abstract: A method for making silicon nanorods is provided. In accordance with the method, Au nanocrystals are reacted with a silane in a liquid medium to form nanorods, wherein each of said nanorods has an average diameter within the range of about 1.2 nm to about 10 nm and has a length within the range of about 1 nm to about 100 nm.
