Looking beyond silicon electronics

Date: Thursday, Feb 28th
Presenter: Prof. Raj Solanki, Department of Physics, Portland State University


The ubiquitous presence of portable electronic gadgets has strongly shaped our lives. This is a result of over 60 years of technology developed to miniaturize the silicon transistor, a basic unit of electronics. However, as the silicon transistor dimensions are rapidly approaching around 10 nanometer scale, the traditional methods and materials are pushed to their limits, hence new avenues are explored to continue this down-scaling trend. Among the possible silicon replacement materials are certain allotropes of carbon that have shown promise. Of these, graphene has been receiving considerable attention. In this presentation, properties of graphene related to electronics and how it may replace Si will be examined.
