Analysis of Torsion Induced Giant Gyrotropy in Hexagonal CdS and CdSe Crystals

Gyrotropy is “weak” in hexagonal CdS and CdSe crystals with symmetry C6v. A strong gyrotropic effect is seen in CdS and CdSe crystals deformed by a torsional moment guided along the optical axis. The instrument utilised is the Polarizer-Crystal-Analyzer (P-C-A).
