First wurtzite-structured MgSiN₂ thin film unlocks promising electronic properties

Wurtzite-structured crystals, characterized by their hexagonal symmetry, are widely valued for their unique electronic and piezoelectric properties—their ability to generate an electric charge when subjected to mechanical stress. Among these, gallium nitride (GaN), a key material in blue light-emitting diodes, and aluminum nitride (AlN), used in high-frequency radio frequency (RF) filters in smartphones, are prominent examples. These materials play a crucial role in advanced semiconductors, sensors, and actuators. Scientists at the Institute of Science Tokyo (Science Tokyo), Japan, have made a significant breakthrough in expanding the wurtzite structure to include heterovalent ternary nitrides, specifically for potential piezoelectric and ferroelectric applications. Their paper, which was made available on February 6, 2025, in Advanced Electronic Materials, describes the fabrication of the first-ever magnesium silicon nitride (MgSiN2) heterovalent nitride in a wurtzite structure with piezoelectric properties.

Wurtzite skyscraper

Resembling some kind of habitat around a distant asteroid on a science fiction book cover, these prisms of zinc sulphide are made of a close cousin of the zinc sulphide sphalerite (seehttp://on.fb.me/1GaU0GY). Wurtzite shares the same chemical formula but crystallises in a different structure, quite a common feature in the mineral world with the varied forms being known as polymorphs (from the Greek for many shapes). It has another unusual feature to its structure, known as hemimorphy (from the Greek for half shape) , in which there is no mirror image symmetry between top and bottom of the crystal, meaning that the top and bottom ends display different faces.

The common form is a six sided prisms or plates often striated parallel to the base, and the usual colour a very dark reddish-orangey brown, often transparent in a strong fibre optic light. It is a soft mineral (3.5=4 on Mohs scale) and relatively dense. It was named in 1861 after a French chemist and is found in veins that have precipitated from metal rich hydrothermal fluids or as concretions in sedimentary rocks during the long arduous passage from sediment to stone.

The photo was taken at magnification, but I sadly don't have the field of view scale data to share with you.

Wurtzite & plagioclase

(wurtzite is a fusion of steven,pearl,amethyst and ruby WITHOUT sapphire) & (plagioclase is a fusion of steven,pearl,amethyst and sapphire WITHOUT ruby) basically the goal was to make wurtzite be the light,fire & magma as plagioclase is more of the cold stone.

There are some big energy shifts coming our way. My guides wanted me to build this grid and share it so that we can start adjusting to this new wave of Light that's on its way. #theevent #5thdimension #crystalgrid #sacredstonegridding #skutterudite #starruby #wurtzite #kambaba #hemimorphite #fluorite #citrine
