Revealing the physics of switching mechanism in 2D materials based memristor devices (2DMEM)

Project description

Exploring the switching mechanism in 2D memristor devices

Neuromorphic computing has enormous potential to transform fields such as AI, robotics, automotive and healthcare, especially if equipped with non-volatile memory devices known as memristors. Recent advances in 2D materials could provide the means to engineer ultra-scaled device dimensions for memory and logic applications. However, there is a lack of systematic atomic scale research in this area. With the support of the Marie Skłodowska-Curie Actions programme, the 2DMEM project will investigate this hypothesis from a physics perspective. With access to extensive experimental data on 2D memristors, it will analyse the electronic properties of 2D materials to uncover the switching mechanism. 2DMEM then aims to integrate realistic material and device features into crossbar structures by using a sophisticated simulation platform.

Objective

One of the most promising non-volatile memory devices and a building block of brain-inspired neuromorphic computing architectures is memristors. The advent of two-dimensional materials (2DMs) has opened a plethora of opportunities in realizing ultra-scaled device dimensions for future logic and memory applications. Despite different hypotheses proposed in the literature, mainly based on analytical models, significant debate is still ongoing, demonstrating the need for a systematic and atomic-scale study. 2DMEM aims to reveal the fundamental physics lying behind each step of device functionality, e.g. SET and RESET. 2DMEM builds on the complementarity of my strengths on investigating the electronic properties of 2DMs, and simulation expertise and infrastructure at the Host Institution, Tyndall, where access to a large interdisciplinary suite of experimental data on the fabricated 2DM memristors is uniquely available. 2DMEM’s specific objectives are to exploit the experimental data of 2DM properties, and to incorporate ‘realistic’ material and device features into crossbar structures by employing an advanced simulation platform. My career development will benefit from the supervision of Dr Lida Ansari, with the mentorship of Profs Paul Hurley, Stephen Fahy and Dr Farzan Gity, who are established research leaders at Tyndall and at Ireland’s materials research center (AMBER). Through this Fellowship, I will develop my scientific, transferable, and management and leadership skills. These skills are essential for achieving my primary career objective of developing into an independent research leader, and will increase my employability in the academic sector. This MSCA Fellowship also creates a unique starting point for me to directly interact with INTEL, who have expressed great interest in this project, through their R-in-R at Tyndall. This will open up additional possibility of leading impactful research projects and fostering industry-academia collaborations.
