Towards scalable graphene (quantum) electronics
Place: conference room, IMDEA Nanociencia.
Abstract:
In this talk I will present our efforts to address the
challenges in scaling up graphene-based technologies, with focus on the
epitaxial growth of graphene (epigraphene) over SiC substrates. Our work
in scalable graphene growth and device fabrication have enabled the
development of practical epigraphene-based devices, including
large-scale Quantum Hall Arrays, Hall effect magnetometers with record
sensitivity, and quantum-limited ultraviolet (UV) detectors. During the
talk I will present details of material and devices, with emphasis in
quantum resistance metrology, for which our epigraphene devices form
nowadays the baseline of quantum standards in several metrology
institutes around the world.
Short bio:
Samuel Lara-Avila is Assoc. Prof. At the Quantum Device
Physics, Chalmers University of Technology. He specializes in the growth
and quantum transport properties of low-dimensional systems, notably
graphene & 2D materials, as well as their use in practical electronics.
His work has been recognized with the 2014 International Union of Pure
and Applied Physics (IUPAP) Young Scientist Prize in Fundamental
Metrology. Since 2021 he is the director of The Graphene Center at
Chalmers, and the Vinnova Competence Center “2DTECH” that aims to
develop industrial applications with 2D materials. He serves as Board
Member in the Swedish Physical Society, Visiting Scientist at National
Physical Laboratory (UK), and Chairman and CTO Graphensic AB.
