HIGH THROUGHPUT UHV GROWTH SYSTEM FOR THE SURFACE ASSISTED BOTTOM-UP SYNTHESIS OF GRAPHENE NANORIBBON
Abstract
Title: High Throughput UHV Growth System for the Surface Assisted Bottom-Up Synthesis of Graphene Nanoribbon HeterostructuresObjective and Expansion ScopeThis is an expansion proposal to an existing ONR BRC grant (N000141211008). The proposed system will be equipped with a competent multistage vacuum system capable of maintaining a base pressure of < 10~8 mbar in the preparation chamber while allowing a fast (< 45 min) transfer of samples into the UHV from ambient pressure. The layout and the performance parameters outlined for the proposed system are designed to reproduce the exact reaction conditions carefully optimized during the method development using an UHV STM/AFM system. The new growth system will be located in immediate proximity to a low temperature (5 K) UHV STM/AFM (Omicron) recently acquired by PI Fischer. The local proximity between STM and growth chamber will provide the capability to continuously monitor the performance of the fabrication process and guarantee a superior level of quality control. The requested instrument is designed with a high degree of automation, remote monitoring capabilities, and high throughput of more than 100 samples per growth cycle (1~2 cycles per day) in mind. The significantly increased sample preparation capabilities provided by a dedicated UHV GNR growth chamber ultimately will significantly accelerate the development, bulk fabrication, and testing of GNR based device architectures supported by a Basic Research Challenge (BRC) grant funded by the ONR (Award no. N000141211008).Statement of Work:PI will be responsible for the entire process of researching, designing, acquiring and testing the instrumentation. The equipment will parallelize the graphene nanoribbon (GNR) growth process and accelerate our understanding of nanomaterials at the molecular scale and help us design functional molecular scale devices and circuits. ONR Relevance:Bottom-up synthesis of graphene nanostructures is a key part of ONR~s nanoelectronics program vision. The requested instrumentation in this expansion proposal will enable the BRC team to prepare large number of homogeneous atomically defined GNR samples required to explore and optimize the fabrication of GNR-based building blocks for advanced electronic integrated circuit architectures such as diodes, transistors, and logic gates. Development of new bottom-up nanoribbon heterostructure devices would represent a major breakthrough in single molecule devices and circuits with great potential benefit to the Department of the Navy.
