Polytypes and twins in new boron-rich chalcogenides B6S and B6Se synthesized at high pressure

Microstructure of new boron-rich chalcogenides, orthorhombic B6X (X = S, Se) synthesized at high pressures and high temperatures, has been studied by high-resolution transmission electron microscopy. Two twins systems have been found along planes {101} and {002}. Apart from numerous twins on the {10...

Description
Summary:Microstructure of new boron-rich chalcogenides, orthorhombic B6X (X = S, Se) synthesized at high pressures and high temperatures, has been studied by high-resolution transmission electron microscopy. Two twins systems have been found along planes {101} and {002}. Apart from numerous twins on the {101} plane, two types of polytypes were found: ABAB in both chalcogenides and AB1CD1AB1CD1 in B6Se. It has been shown that shear bands in B6S and cracks in both materials lie in planes {011}. •Microstructure of new boron-rich chalcogenides B6X (X = S, Se) was studied by HRTEM.•Two types of polytypes: ABAB in both chalcogenides and AB1CD1AB1CD1 in B6Se were found.•Two twins systems have been found along planes (101) and (002).
