Chang Liu, Research Associate, Monash University

Chang Liu is a Research Associate studying the electronic properties of atomically-thin topological materials with Julie Karel at Monash University.
The topological materials studied can be tuned to transition between being an electrical insulator and a topological insulator, raising the opportunity to create a switched topological transistor, which would consume much less energy than conventional electronics.

Chang seeks new materials that possess the distinct topological phases with potential to transport charge without dissipation. He also investigates capping techniques to protect those materials from air, methods to grow the high-quality, ultra-thin materials on a substrate, and to fabricate ultra-thin films into functional transistors.

Epitomising FLEET’s cross-field collaboration, Chang’s research falls within the Centre’s Research theme 1, Enabling technology A and some of Enabling technology B.
