The samples are characterized by high-resolution transmission electron microscopy, scanning electron microscopy, X-ray diffraction, and Raman spectroscopy. The growth mechanism and the role of transition metal particles in forming nanowires is discussed. — (CHOI, YOUNG CHUL; KIM, WON SEOK; PARK, YOUNG SOO; LEE, SEUNG MI; BAE, DONG JAE; LEE, YOUNG HEE; PARK, GYEONG-SU; CHOI, WON BONG; LEE, NAE SUNG; KIM, JONG MIN; Adv.
