2D Material Based Memristors - the Promising Alternative in Post-Moore Era

PhD defence, Monday 3 October 2022, Xuya Xiong.

Xuya Xiong

During his PhD studies, Xuya Xiong researched 2D material based memristors. Memristor, the fourth basic circuit element, has been examined as a promising alternative for non-volatile storage, logic circuit and neuromorphic computing. In 2D material based devices, the working principle, mechanism and physiochemical property vary greatly. Xuya Xiong studied the resistive switching mechanism and in situ characterization on various memristive systems.

The new research findings contribute to the in-depth understanding of conductive dynamics, ranging from dimensional change to physicochemical regulation with the goal of laying a solid foundation for cutting-edge devices.


The PhD study was completed at Interdisciplinary Nanoscience Center (iNANO), Faculty of Natural Sciences, Aarhus University.

This summary was prepared by the PhD student.
