Abstract
Robotic Assembly of High-Quality CNT Devices
Carbon NanoTubes (CNTs) are promising candidates for sensing, high-performance transistors [1] and quantum computing [2,3]. However, to enable any robust industrial application of these materials, one needs to gain a better understanding and control of their properties during growth and integration.
At Chiral, we combine high precision robotics and advanced data analysis to develop high speed and precision robots that can assemble high quality nanomaterials on a 4-inch wafer with more than 1000 transfers per hour. In this talk, I will present our workflow for the growth and integration of high quality SWCNT into a FET geometry.

Biography
Maria El Abbassi holds a PhD in nanoelectronics from the University of Basel and a Master’s degree in Fundamental Physics from the École Normale Supérieure and Polytechnique. She has +10 years of experience in nanotechnology and has led major technical projects through several roles: TU Delft (postdoc) C12 (head of characterization) and now Chiral (head of R&D). On a technical level, she achieved the first demonstration of a robust graphene molecular transistor and the first measurement of a graphene nanoribbon quantum dot.
