Ordered arrays of rare-earth silicide nanowires on Si(001)
Abstract
Ordered arrays of self-assembled ErSi2-x, SmSi2-x, and DySi2-x nanowires aligned along Si [110] have been grown at 600°C on Si(001) vicinal substrates. The nanowires grow perpendicular to the Si dimer rows and are 1.5-5nm wide, approximately 2 monolayers high and up to 1μm long. These nanowires were characterized in situ with scanning tunneling microscopy. © 2002 Elsevier Science B.V. All rights reserved.
