Rsearchers produce first 2D perovskite hybrid sheets

To the growing list of two-dimensional semiconductors, such as graphene, boron nitride, and molybdenum disulfide, whose unique electronic properties make them potential successors to silicon in future devices, you can now add hybrid organic-inorganic perovskites. However, unlike the other contenders, which are covalent semiconductors, these 2D hybrid perovskites are ionic materials, which gives them special properties of their own.

Proposed standards for triboelectric nanogenerators could facilitate comparisons

To provide a means for both comparing and selecting these energy-harvesting nanogenerators for specific applications, the Georgia Institute of Technology research group that pioneered the triboelectric nanogenerator (TENG) technology has now proposed a set of standards for quantifying device performance. The proposal evaluates both the structural and materials performance of the four major types of TENG devices.

Doping crystals of nanocrystals

Crucial to silicon semidconductor applications is the ability to 'dope' the semiconductor; which is to say, by controllably adding impurity atoms to a semiconductor, one can continuously vary its electronic and optical properties. Scientists now have demonstrated for the first time, a unique nanoscale analogue.
