Changing the Properties of a Topologically Insulating Film through Bending

■ Natural Sciences / Changing the Properties of a Topologically Insulating Film through Bending A group of researchers, including Prof. Mann-Ho Cho, examines the effects of strain on three-dimensional topological insulators Can the properties of a topologically insulating film be tuned by bending? And are such changes reversible? Park, Chae, Jeong, Kim, Choi, Cho, Hwang, Bae, and Kang (2015) have answered these questions in their paper, “Reversible Fermi Level Tuning of a Sb2Te3 Topological Insulator by Structural Deformation,” published in Nano Letters. Building on previous theoretical and experimental work showing the influence of structural deformation on three-dimensional (3D) topological insulators, the authors examined the effect … Continue reading Changing the Properties of a Topologically Insulating Film through BendingRead More →
