Latest Patents

Carruthers's recent innovations include several key patents:

1. **Graphene formation utilizing solid phase carbon sources** - This method describes how to create single, few-layer, or multi-layer graphene by selecting a substrate with a buried layer of carbon beneath a metal layer. The process involves providing an ambient environment and applying heat treatment to facilitate the migration of carbon through the metal layer, thus forming a graphene layer on the surface. Additionally, it explores the segregation of carbon to the surface through the reaction of a metal-carbon layer with a silicon-containing substrate.

2. **Self-aligned metal to form contacts to Ge containing substrates** - This invention outlines a technique for forming germano-silicide contacts atop a Ge-containing layer, offering enhanced etching resistance compared to conventional silicide contacts made from pure metal. The method includes creating a structure with gate regions on a Ge-containing substrate, applying a silicon-containing metal layer, and performing annealing to generate a germano-silicide compound at the interface. The selective removal of any unreacted metal layer results in a contact layer rich in silicon atop the Ge substrate.
