Oriented bottom-up growth of armchair graphene nanoribbons on germanium

Title: Oriented bottom-up growth of armchair graphene nanoribbons on germanium

Graphene nanoribbon arrays, methods of growing graphene nanoribbon arrays and electronic and photonic devices incorporating the graphene nanoribbon arrays are provided. The graphene nanoribbons in the arrays are formed using a scalable, bottom-up, chemical vapor deposition (CVD) technique in which the (001) facet of the germanium is used to orient the graphene nanoribbon crystals along the [110] directions of the germanium.

Methods of fabrication of graphene nanoribbons

Patent Zhang, Yuegang

Methods of fabricating graphene nanoribbons include depositing a catalyst layer on a substrate. A masking layer is deposited on the catalyst layer. The masking layer and the catalyst layer are etched to form a structure on the substrate, the structure comprising a portion of the catalyst layer and a portion of the masking layer disposed on the catalyst layer, with sidewalls of the catalyst layer being exposed. A graphene layer is formed on a sidewall of the catalyst layer with a carbon-containing gas.

Method for enhancing growth of SiO.sub.2 in Si by the implantation of germanium

Patent Holland, Orin W. ; Fathy, Dariush ; White, Clark W.

A method for enhancing the conversion of Si to SiO.sub.2 in a directional fashion wherein steam or wet oxidation of Si is enhanced by the prior implantation of Ge into the Si. The unique advantages of the Ge impurity include the directional enhancement of oxidation and the reduction in thermal budget, while at the same time, Ge is an electrically inactive impurity.
