PhD studentship in graphene and 2D materials for thermal management of flexible and wearable electronics

Applications are invited for a fully-funded PhD studentship to work on Anisotropic nanostructured materials based on graphene and 2D materials for thermal management and heat dissipation in next generation electronic circuits, specifically in flexible and wearable electronics.

Description: Electronics is ubiquitous in our everyday life. Faster and smaller electronic devices require the miniaturisation of several electronic components distributed on chips with ever-growing capacity. The heat generated by electronic devices increases exponentially with the density of electronics on the same chip, limiting the performances of miniaturized integrated circuits. Anisotropic thermally conductive materials able to dissipate heat in one or two in-plane spatial directions while barring the conductivity on the out-of-plane direction are ideal materials to dissipate heat effectively, without affecting the surrounding devices. The current materials employed for thermal dissipation suffer from intrinsic physical limitations. Along with graphene a whole new family of two-dimensional (2D) materials has recently emerged with extraordinary electrical, thermal, optical and mechanical properties. Some of these materials (e.g. graphene or hexagonal Boron Nitride, h-BN) have shown excellent thermal conductivity with orders of magnitude improvement and have the ideal set of properties to pave the way to a next generation thermally conductive materials. This project aims to engineer new polymer composites embedding graphene and/or hybrid two-dimensional materials (such as h-BN) with a high concentration and explore their use as highly electrically, thermally conductive pastes and composites for integrated electronic circuits. Electrical, thermal conductivity will be characterised and viscoelastic properties of the polymer composites and pastes will be investigated and tailored for deposition techniques such as extrusion, and 3D printing. The 2D-materials based inks with thermal and electrical properties will also be used to engineer anisotropic inkjet printed multi-layer devices with conducting, semiconducting and insulating properties for printed transistors, thermoelectric generators and capacitors. Given the growing interest in wearable electronics and smart textiles, the integration of these 2D materials with fabrics, fibres and yarns will be explored. The ultimate goal is to achieve a new family of electrically insulating and thermally conducting pastes and polymer composites with highly anisotropic properties that can be deposited by the most modern deposition technologies, including 3D printing.

The student will be fully incorporated into the Molecular Science Research Hub offering a unique opportunity to interact with teams of researchers working on Synthesis, Nanomaterials, Energy, Imaging & Sensing, Plastic Electronics.

Wearable Nano-Electronics: Wearable electronic devices based on graphene and other layered materials (in collaboration with Google Advanced Technologies and Projects and the University of Cambridge)

Wearable electronics are at the core of academic and industrial research and development in the strategic areas of healthcare and wellbeing, Energy generation and harvesting. Wearable electronics currently relies on rigid and flexible electronic technologies, which offer limited skin-compatibility in many circumstances, suffer washing and are uncomfortable to wear because they are not breathable. Turning natural fibres and textiles into electronic components will address these issues, by unlocking ultimately wearable electronics potential through electronic textiles.

The 2DWEB group has demonstrated that graphene and other two-dimensional materials enable superior wearable electronic textile devices, such as transistors and memories (T. Carey et al., Nature Comms. 8, 1202, 2017). The aim of this PhD project is to develop a new class of wearable electronic devices based on inks and composites of graphene and other layered materials, their supramolecular structures and hybrid platforms, combining the versatile properties of layered materials with fibres and textiles. The electrical and optical properties of such devices will be characterised aiming at wearable electronic applications, such as biosensors and bio-medical devices devices.

This is a highly innovative PhD project, with a strong interdisciplinary nature, across chemistry, nanoscience, physics and electronics of two-dimensional materials aiming at the realization of novel wearable devices for several applications such as the Internet of Things, Body Area Networks, Healthcare and Wellbeing devices and Smart fabrics. The project also provides an exciting opportunity to work across the  research fields of printed electronics and two-dimensional materials (Dr Torrisi), chemistry of nanomaterials (Dr Siva Bohm, University of Cambridge)  and future wearable technologies (Google ATAP).

Two Research Associate roles in semiconducting polymer synthesis

Campus: White City campus and South Kensington campus

Two post-doctoral research positions in synthetic polymer chemistry are currently available within the group of Professor Iain McCulloch at Imperial College, London.  The successful candidates will join an inter-disciplinary team working on the development of novel organic semiconducting materials for a range of organic electronic applications including photo voltaics, spintronics and photocatalysis. 

The roles will involve the synthesis of organic conjugated semiconducting polymers and small molecules.  You will be expected to interact with fabrication and measurement collaborators, as well as undertake materials characterization.  There is the opportunity to supervise research students, and manage external collaborations.

You will have a PhD in Organic Polymer Chemistry, or a related field, with specific experience and understanding of state of the art metal mediated aromatic carbon – carbon coupling reactions of conjugated semiconducting polymers.  Applications are strongly encouraged from candidates who have demonstrated an ability to design high performing solution processable organic semiconductors for organic electronic applications. You will also have a strong publication record commensurate with your career stage, and experience of presenting work at international conferences. You will also have excellent verbal and written communication skills, along with a creative approach to problem-solving, and the ability to organise your own work and meet project deadlines with minimal supervision.

For any additional clarification regarding the scientific aspects of the position, please contact Prof. Iain McCulloch (i.mcculloch@imperial.ac.uk).
