Characteristic growth features and etching of SnSe single crystals

Özet

SnSe Single Crystals have been grown by the Bridgman-Stockbarger method. Hexagonal spirals observed on top-free surface of the crystals have been reported. Crystal growth by screw dislocation mechanism has been found to be dominant: A new etchant capable of revealing dislocations intersecting the cleavage plane is also reported.
