Research Abstract

Carbon, which allotropes are well known as graphite and diamond, exhibits various phases such as fullerene, carbon nanotube and graphene.
Fundamental and technological interest in development of new carbon based device has encouraged pursuit of new carbon phase with novel structural and electronic properties. This project focused on the structural phase transition in graphite induced by femtosecond laser excitation (1 femtosecond = 10-15 second), and studied to elucidate the mechanism from a microscopic point of view by using scanning tunneling microscopy.
