Fabrication and Characterization of Flexible CuI-Based
Both CuI and CuI:Zn semiconductor thin films, along with MSM-structured UV photodetectors, were prepared on flexible mica substrates at low temperature (150 °C) by a wet chemical method. The two CuI-based films exhibited a polycrystalline phase with an optical bandgap energy close to 3.0 eV. Hall effect measurements indicated that the CuI thin film …

Mica | PDF
Commercially important mica minerals are muscovite (potash or white mica) and phlogopite (magnesium or amber mica). Granitic pegmatites are the source of muscovite sheet, while phlogopite is found in areas of metamorphosed sedimentary rocks into which pegmatite rich granite rocks have been intruded. ... These mica-pegmatites may have formed at ...

Mica Schist: Rockhounds Guide to Formations, Uses, and Value
There are numerous types of Schist rocks, Mica being one of many. Mica Schists are the most common Schistose rocks and the second most common metamorphic rocks on Earth. These rocks are composed mainly of Mica (usually Muscovite or Biotite) and smaller amounts of Quartz. The original protolith or parent rock of Mica Schist is Shale.

Muscovite thin section
Relief: Moderate positive Habit/Form: Well-formed tabular crystals with a roughly hexagonal outline are rare. Usually found as micaceous flakes or tablets with irregular outlines, tabular parallel to {001}. Sericite is name given to very fine, ragged grains and aggregates of white mica – usually muscovite – produced by the alteration of feldspars or other minerals.
