Abstract:
1. A method of growing an elongate nanoelement from a growth surface comprising: a) cleaning a growth surface on a base element; b) providing an ultrahigh vacuum reaction environment of less than 10 c) generating a reactive gas of an atomic material to be used in forming the nanoelement; d) projecting a stream of the reactive gas at the growth surface within the reactive environment while maintaining a vacuum of at most 1.times. 10.sup.-4 Pascal, wherein the reactive gas comprises a cracked hydrocarbon species; e) growing the elongate nanoelement from the growth surface within the environment while maintaining the pressure of step c); f) after a desired length of nanoelement is attained within the environment, stopping direction of reactive gas into the environment; and g) returning the environment to an ultrahigh vacuum condition of less than 10
