13 Graphene Radical technology = Significantly higher performance over the state-of-art Generic technology = Wide range of potential applications Disruptive technology = It offers new value propositions GRAPHENE S SUPERLATIVES ü Thinnest imaginable material ü Largest surface area (2700 m^2 per g) ü Strongest material ever measures (theoretical limit) ü Stiffest known material ü Most stretchable crystal (up to 20 % elastically) ü Record thermal conductivity (outperforming diamond) ü Highest current density at RT (10^6 times of Cu) ü Compete impermeable (even for He atoms) ü Highest intrinsic mobility (100 times more than Si) ü Conducts electricity in the limit NO electrons ü Lightest charge carriers (zero rest mass) ü Longest mean free path at room T (µm scale) 13

14 Horizontal Platform, Vertical Integration Graphene is a versatile material that will be used to improve the performance of various electrical components and/or to create new components Ø Supporting existing value chains and developing horizontal technologies Graphene can be an enabler for new manufacturing paradigms (printing, R2R) that integrate different components into integrated functional systems Ø Disrupting existing value chains and creating vertically integrated novel products Materials Versatile functional material Components Integrated functional systems For example, sensors, signal processing, communication, and energy End products End products 14

15 Technology Differentiation and Disruptions in Manufacturing Europe can compete by radically differentiating technologies Europe can t compete by minimizing costs of traditional technologies. Europe can compete by providing truly disruptive manufacturing solutions not by incremental development steps for existing manufacturing capabilities. 15
