2D Materials, from Academia to Industry

Semiconductor sales will reach over $500 billion worldwide in 2021, a gigantic industry that keeps on growing with increasing demand for faster, more powerful, and smaller chips. However, as we keep scaling, the silicon (Si) transistor will soon reach its physical limit, and there is a pressing need to find an alternative post-Si material to enable the continuation of Moore’s Law.

In the early 2000s, scientists discovered that graphite could be exfoliated down into an atomic form, going from a 3D bulk material down to a 2D stable honeycomb lattice of carbon atoms called graphene. Scientists marveled at graphene’s astonishing electrical and mechanical properties, however, for all that graphene has to offer, it lacks a band gap that is essential for logic devices. This created a surge in research on materials beyond graphene, scientists searching for an elusive 2D material that would possess a bandgap to satisfy the need of the semiconducting industry. Monolayer Transition Metal Dichalcogenides (TMDs) possess the bandgap that graphene lacks, and with the vast variety of TMDs available, coupled with its encouraging electrical properties, make TMDs a promising candidate.

In this talk, I will present my years of research on 2D materials focusing on TMDs, from synthesis and characterization to innovative applications. I will demonstrate a scalable method for monolayer TMD growth and integration, its applications (e.g. opioid biosensor and flexible electronics), the first report of monolayer growth and electrical characterization of the unstable 1T’ TMDs, and in-plane monolayer TMD heterostructures with different metal atoms or atomic phases. I will also discuss some of Intel’s industrial research to date on 2D materials, how TMDs and other 2D materials are finding their way into production and potentially into everyone’s day to day life.
