Introduction

Chiral dopants, also called a doping agent, is a trace impurity element that is inserted into a substance (in very low concentrations) to alter the electrical or optical properties of the substance. In the case of crystalline substances, the atoms of the dopant very commonly take the place of elements that were in the crystal lattice of the base material. The crystalline materials are frequently either crystals of a semiconductor such as silicon and germanium for use in solid-state electronics, or transparent crystals for use in the production of various laser types; however, in some cases of the latter, noncrystalline substances such as glass can also be doped with impurities.

The dopants can be useful for building additional thickness of the electrodeposited mineral layer.

The conductivity of such these semiconductors can be altered by the deliberate addition of impurity atoms known as dopants.

There are important technological uses for chiral dopantmaterials. They are used in low concentrations in twisted nematic displays, and in chiral films for use with displays. Theycan also be used in polarization sensitive polymer films and thermally addressed display materials. In many applications.however, limits on solubility of the dopant, or specific material requirements mean that only small concentrations of chiral dopants can be employed.
