Help us to bring 2D materials into devices
Two-dimensional (2D) materials are promising candidates for integration in future electronic, (bio)sensing, photonic and even energy applications thanks to their numerous exciting physical properties like high thermal conductivity, flexibility, tuneable light absorption, superconductivity, high mobility, etc. Some examples of available 2D materials include transition metal dichalcogenides (e.g., MoS2, MoSe2, WS2...), graphene, phosphorene, and h-BN. To foresee their integration in new technologies, two strategies are currently investigated by the community: direct growth and transfer, both presenting specific challenges to meet industry requirements, but also advantages.
Transferring 2D materials opens a wide range of applications. For example, to use highly crystalline materials, since such layer are grown at hight temperature (>>700C) and on specific substrates. It is also the opportunity to investigate and optimise interfaces with surrounding material or to realise layers stacking.
In the last years, our team has developed a transfer process that can be adapted to the different 2D materials available at imec. However, to guarantee the delivery of hight quality material for devices, the process needs optimisation. In particular, the interfaces of the delivered layer, top and bottom, is of the outmost importance because the surrounding can induce doping. Knowing that, we want to investigate the possibility of modifying their properties by controlling the interfaces and minimising the defects.
What you will do
The project is experimental and requires working most of the time in the clean room (wet bench and glove box). Activities include manipulation of chemicals to clean and prepare the samples, physical characterisations (optical microscopy, AFM, PL spectroscopy among others) and the analysis of the data. All the necessary training will be provided.
The 2D team is international (currently 5 different nationalities), we work in English and in close collaboration with a lot of informal meetings. As a member of the team, the student is expected to present her/his results in our biweekly group meeting and to participate in discussions.
