Optical imaging of strain in two-dimensional crystals

Strain is an effective tool to tune the optoelectronic properties of two-dimensional materials. Here, the authors demonstrate that second harmonic generation can be used to extract the full strain tensor of MoS2 and to spatially image its two-dimensional strain field.
