Periodic Reporting for period 1 - dryhetero (Novel, high-throughput compatible dry transfer approach to enable high performance, suspended CVD 2D material heterostructure electronic devices and their applications)

Reporting period: 2021-12-01 to 2023-11-30

Summary of the context and overall objectives of the project

Graphene is a novel two-dimensional material which combines various electrical, mechanical, and optical properties such as high field-effect mobility, high mechanical strength and high transparency. Using chemical vapor deposition methods, graphene films can be produced in large quantities suitable for industrial applications. However, the performance metrics of synthetic graphene films are typically lower than exfoliated graphene films. In this project various methods to improve the performance metrics of graphene devices are explored.
High performance graphene devices can be useful to develop various sensing applications such as biosensing applications. A device architecture consisting of free-standing graphene films was extensively explored during this project, facilitating the observation of enhanced field-effect mobility in graphene devices. In addition, methods to study intrinsic strain and defect density in graphene films was explored.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

During the MSCA post-doctoral fellowship project up-to five peer-reviewed publications reporting on the enhanced performance metrics and methods to study graphene film properties was realized. The project findings were disseminated during one regional science communication events to the public.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

Key project findings extend the state-of-the-art findings on CVD graphene by reporting enhanced performance metrics and methods to characterize graphene films via non-invasive fabrication methods. In addition, the project contributes to the field by reporting fabrication methods and techniques to facilitate further exploitation of the results.
