We are proud to announce that the 1D-NEON Webinar series remains a success!​

The 2^nd webinar titled ‘Fibre Components and Modelling/Simulation’ was provided by 1D-NEON partners UNINOVA, University of Oxford  and Silvaco on 25^th May 2018 and 35 attendees from 6 different countries registered.

Thank you to our Organizing Partners UNINOVA, University of Oxford  and Silvaco for such an interesting event and YOU for attending!

Title: Fibre Components and Modelling/Simulation

This course will focus on fibre components being developed within the project with potential for innovative applications as textile wall curtains or wall displays. Fibre stretchable electrodes and interconnects, fibre transistors and fibre LEDs will be discussed regarding their fabrication and properties, being shown how modelling/simulation activities greatly help on their development.

Regarding transistors, the presentation will focus on the different structures possible to conceive on fibres, particularly gate-all- around and pseudo-planar structures, analysing their advantages/disadvantages regarding performance, processing and integration. The main challenges on bringing thin-film technology into polymeric fibre shapes and possible solutions will be discussed, always envisaging low-cost and large-scale fabrication of these components.

Regarding F-LED, the course will provide the knowledge and skill of the F-LED device. The skill presented in this course will lay the protocol on the preparation and characterisation of emissive functional nanomaterials – quantum dots - as well as the design and fabrication of emissive fibre through the cost-effective process. The demonstration of lighting textiles with the F-QLED to understand the feasibility of next-generation lighting devices will also be discussed.

Silvaco will describe the available design software tools to model charge transport and device performance using materials for large area electronics. The numerical approach for Technology Computer Aided Design (TCAD) will be summarised together with the bespoke models describing the density of states profiles within the band gap of these materials and the associated carrier mobilities. Of paramount importance is the meshing engine to create 3D structures that mimic the aspect ratio of these devices and the realisation of non-planar substrates. Recent data of the impact of such curvature on the device performance will be presented.

The course content includes:

• Introduction to fibre components being developed within the project
• Fibre transistors: device structures, performance, processing and integration
• Fibre LEDs:
  • Emissive nanomaterials and LEDs introduction
  • F-LED device fabrication and characterisation
• Modelling/simulation:
  • Why use design models
  • How to explore available design space
  • Numerical approach for TCAD
  • Available material models
  • The impact of the form factor on device performance.
