Mica Polytypes: Systematic Description and Identifiion
Abstract. Xray studies of mica specimens from a variety of geological localities show that biotite and certain lithiumrich mica samples are composed of a mixture of different polytypes. Many of the biotite structures are new complex polytypes not before reported. A new method of designating mica polytypes is proposed....
Transition metal dichalcogenides | Max Planck Institute ...
Dichalcogenides. Recent discoveries of superconductivity and charge density wave in two dimensional transition metal dichalcogenides (TMDs) have created lot of excitement in this class of materials. Electronic properties and therefore transport behavior in these materials depend on the anionic environment around metal ions....
