| | | Description | Straintronics in 2D materials
Recently, strain has emerged as a means to control material and device properties on an unprecedented scale. Two-dimensional (2D) materials are ideal “ultra-strength” systems for tuning properties via strain: they host rich strain-induced quantum behavior, while the lower dimensionality enables new kinds of symmetry changing deformations. However, in many next generation technologies including heterogeneous integration of 2D materials with CMOS processes, wearable electronics, and quantum systems, strain is an important yet unknown or uncontrolled parameter. In this talk, we examine the nanoscale interfacial mechanics for strain engineering in 2D materials, and their influence on the electronic properties and device transport. For example, we demonstrate designable strain using thin film stressors to spatially pattern the electronic structure of 2D monolayers and heterostructures. We then leverage these fundamental insights to apply strain and deformation engineering across a broad range of applications such as mobility enhancement in 2D transistors and stretchable electronics. |
