Topological insulator MBE is performed in high vacuum or ultra-high vacuum, the elements are heated in different electron beam evaporators until they sublime. The gaseous elements then condense on the wafer where they react with each other to form single crystals. MBE is an appropriate technique for the growth of high ...

Topological insulator Thus far, the field of topological insulators has been focused on bismuth and antimony chalcogenide based materials such as BiSe , BiTe , SbTe or BiSb, BiSbTeS. The choice of chalcogenides is related to the Van der Waals relaxation of the lattice matching strength which restricts the number of mat...

Topological insulator These crystal structures can consist of a large number of elements. Band structures and energy gaps are very sensitive to the valence configuration; because of the increased likelihood of intersite exchange and disorder, they are also very sensitive to specific crystalline configurations.

Gold chalcogenides are compounds formed between gold and one of the chalcogens, elements from group 16 of the periodic table: oxygen, sulfur, selenium, or tellurium. Natural gold tellurides, like calaverite and krennerite (AuTe), petzite ( AgAuTe), and sylvanite (AgAuTe), are minor ores of gold (and tellurium). See tel...
