Synthesis and integration of wafer-scale van der Waals heterostructures for industrial nanoelectronic devices

Project description

Two-dimensional materials for the post-Moore's law era

The information technology industry has been piggybacking on Moore's law for delivering successive generations of cheaper and more powerful microchips. According to forecasts, though, Moore's law will end by around 2025. Therefore, the industry is searching for other materials with semiconducting properties that could form the basis for an alternative chip. Efforts to build practical and commercial electronic devices using 2D materials have foundered on concerns over their complex synthesis and manipulation. The EU-funded 2D-HETERO project plans to overcome these challenges by synthesising Van der Waals heterostructures based on different 2D materials and stacking the materials on top of each other. To achieve its goals, the project will conduct interdisciplinary research that will span materials science, physics, chemistry and electrical engineering.


Moore’s law has enabled the $4 trillion worldwide IT industry to nearly double the performance and functionality of digital electronics roughly every two years within a fixed cost and area. However, the International Semiconductor Technology Blueprint (ITRS) predicts that the technological underpinnings for Moore’s law will end by 2025. IRTS points out that two-dimensional (2D) materials will bring new opportunities for the Post-Moore Era, especially for the CMOS technology beyond 5 nm node. However, very few 2D materials based electronic products are available commercially over the decades of study. With the scaling-down of the electronic devices, it is urgent for academia and industry to seek ways to integrate 2D materials in practical and commercial electronic devices. Introducing 2D materials in the structure of commercial electronic devices is challenging due to their complex synthesis and manipulation. The 2D-HETERO project will explore large wafer-scale (from 2-inch to 300 mm) and uniform growth of different 2D materials by chemical vapor deposition (CVD) method. Van der Waals heterostructures based on different 2D materials will be developed by stacking 2D materials through the direct growth or through clean and large wafer-scale transfer methods. The developed high quality and wafer-scale van der Waals heterostructures will be integrated in different nanoelectronics (mainly field effect transistors), with the goal of enhancing the device performance, yield and uniformity. Using an interdisciplinary approach that combines materials science, physics, electrical engineering, industry-relevant nanofabrication and characterization, 2D-HETERO will pave the way to industrialize 2D materials based nanoelectronics. The combination of learning through research and a comprehensive training plan, including both scientific and technological as well as soft skills, will strongly enhance the profile of the applicant and provide a boost for her future scientific career.
