3D Printing 2D Materials
Tomas A. Palacios
Our project aims to mesh the world of 3D printing with advancements in the field of thin film electronics to create customized products with enhanced capabilities. Ink Jet printing in particular has benefits to microelectronics production as the process is versatile, involves a limitted number of steps, and can deposit a controlled amount of material at the nano/microscale level. We will work to develop a 3D printing system and inks that produce circuits based on the two dimensional materials that are being investigated in the Palacios lab, such as molybdenum disulfide and graphene. I will be researching and developing the printer head system to meet our needs in printing conductive patterns on the micrometer scale and developing a molybdenum disulfide ink to print high mobility transistors. Next semester we will work on a demonstration of our 3D printer’s capabilities by printing either a display or sensor application.
I have been working in the Palacios lab to design and fabricate the backplane circuitry for an organic LED display using MoS2 transistors. This has helped me understand the materials we use to make transistors and the benefits and limits to the processes currently used to fabricate transistors made of 2D materials.
