Substituting

The NEED project will specifically address research towards innovative data storage technologies, CMOS-compatible photonics devices, and sensors.
Our strategy is to identify and qualify new abundant materials such as ultra-thin oxide-based dielectrics, 2D materials and carbon films, and III-V semiconductors to replace thicker building blocks involving the use of ever-scarcer noble metals, indium and new lead-free ferroelectric and piezoelectric materials for sensors and actuators.

The objective of the WP2 is to focus on reductions and substitutions of rare materials (Task 1), developments of new green and sustainable processes (Task 2) and creation of functionalities based on novel physical concepts (Task 3).

Task 1

Developing processes either to save or substitute rare materials to realize specific functions such as data storage (ReRAM, STTRAM, etc.), light emission and detection, and sensors. Materials synthesis process compatible with large-scale integration, namely atomic layer deposition, physical vapour deposition, metal-organic chemical vapour deposition, and chemical vapour deposition will be developed and studied.

Task 2

Integrating ultra-thin films into single-device test-vehicles and devices arrays on large-area substrates thanks to clean-room environment of advanced and complementary technological platforms. The physical properties of the devices will be thoroughly characterized and modelled, with the aim to understand and optimize their operation and establish their use in circuits/system

Task 3

Structuring the full interaction chain from academic laboratories, to actors of the transfer to industry, and industrial partners, which is a known critical weakness in researches on two-dimensional (2D) materials nowadays. Owing to their ultimate thinness and the unique quantum effects that they host, these 2D materials bring a new toolkit of functions of high relevance for future IoT, while only using minute amounts of materials.
