Two-dimensional Materials for Internet-of-Things Applications: Logic, Memory, and Flexible Sensor

Abstract

High performance and low power devices are compelling for Internet-of-Things (IoT) applications. However, the currently used materials are approaching their physical scaling limit, thus there is an urgent need to find new materials and device architectures to extend Moore’s law. In this circumstance, novel materials, such as two-dimensional (2D) materials have attracted tremendous research interests due to their superior properties, including its atomic thinness, inherent flexibility, high mobility, and compatibility with existing CMOS technologies, manifesting their potential for logic devices, memory devices, and flexible electronics, which form the building blocks to construct high-performance IoT system. However, 2D materials research is still at the nascent stage, and there co-exists both opportunities and challenges in this area. This thesis aims to realize multiple high-performance logic and low power devices on both rigid and flexible substrates based on 2D materials platform for IoT applications.
