Sample of MoS2 (image) Columbia University School of Engineering and Applied Science Share Print E-Mail Caption Researchers from the Georgia Institute of Technology and Columbia Engineering have made the first experimental observation of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide (MoS2). Shown is a sample of the material that was tested as part of the research. The material could be the basis for unique electric generator and mechanosensation devices that are optically transparent, extremely light, and very bendable and stretchable.
