Large Area Graphene and Related Materials for Si and Wearable Nanosystems
Abstract
Title: Large Area Graphene and Related Materials for Si and Wearable NanosystemsObjective:To carry out applied research based on a common platform, namely, rapidly maturing large-area monolayer graphene. The two major areas that are ripe for significant translational advancement are: i) scalable dry delamination transfer ofmonolayer graphene for wafer-scale Si integration, and ii) active graphene-based electronic tattoos.Approach:The two proposed research thrusts are briefly summarized below:Thrust 1: Scalable Dry Graphene Delamination Transfer. Facile, fast, and clean route to transfer CVD graphene grown on polycrystalline metal (Cu) or single-crystalline (Ge) onto full 100 mm Si wafers using dry mechanical delamination methods for the first time.Thrust 2: Graphene-based Electronic Tattoo (GET) Active Sensors. Focused research and development on wearable graphene with integrated 2D semiconductors to realize active tattoo sensors for the first time with improved signal to noise ratio and fidelity.SOW:From a technical point of view, the two proposed thrusts represents complimentary and parallel research activity focused on graphene-based technology with the goal of bringing scientific discoveries in the lab to a higher TRL level. For research thrust 1 on dry transfer, the first 18 months will focus on basic experiments on dry transfer of graphene from Cu and Ge substrates to silicon substrates, while the latter 18 months will advance scale up of transfer to100 mm wafers. The main innovations in terms of technology concepts will be i)microelectronics compatible polymer adhesive, in lieu, of the epoxy used in our prior work, and ii) center loading to enable near-instantaneous dry delamination onto the target wafer. Research thrust 2 will expend 24 months for researching and integrating 2D transistor amplifiers on graphene based electronic tattoos. The subsequent 12 months will conduct both simultaneous recording of several physiological signals and long-term studies to determine the failure mechanisms in a practical setting with the tattoo worn by an active user.
