SUMMARY:ESE Seminar: "Efficient Mid-Infrared Photodetection Using Graphene Plasmons at Room Temperature"
DESCRIPTION:In the history of materials development\, many classic materials (Si\, III-Vs\, organics\, etc.) which can be produced reliably at large scale eventually have found critical applications after decades of intensive research\, leveraging their distinctive properties. For example\, silicon dominates the field-effect-transistor technology because perfect dielectric-silicon interface can be readily realized. Organic materials are currently widely used in flat-panel displays\, because of their great light emitting properties and the availability of cost-effective production techniques. In this talk\, I will first discuss the unique properties of graphene\, the first two-dimensional material isolated about 15 years ago\, including ultralow heat capacity\, high mobility\, and weak electron-phonon coupling strength. Leveraging these unique properties\, I will then present an efficient mid-infrared photodetector based on graphene plasmons operational at room temperature. Since high-quality wafer-scale graphene can already be produced routinely\, such efficient mid-infrared photodetectors may find applications in high-speed thermal imaging and free-space communications.
