Straining a Monolayer Lattice (IMAGE) Stanford University School of Engineering Caption Molybdenum disulfide (MoS2) is the semiconductor material no one's ever heard of until recently. This graphic shows how a layer of MoS2 just three-atoms-thick stretches over the nanoscopic hills and valleys of this electronic device like a wet t-shirts clings to skin. Stretching this semiconductor material creates unique electronic properties geared toward solar power.
