Fabrication techniques of group 15 ternary chalcohalide nanomaterials

Group 15 ternary chalcohalides (i.e., in the old notation: A^VB^VIC^VII compounds, where A^V = Bi, Sb, As; B^VI = S, Se, Te, O; C^VII = I, Br, Cl, F) contain ferroelectric semiconductors that have a large number of interesting properties. In this review, the following fabrication techniques of group 15 ternary chalcohalide nanomaterials are summarized: preparation of composite materials (SbSI dots in sodium borosilicate glass; SbSI dots in organically modified TiO2 glass; electrospinning of fibers and mats; fabrication of piezoelectric paper), ball milling of bulk crystals, vapor-phase growth of SbSI nanorods, graphoepitaxy, sonochemical synthesis of SbSI-type nanowires, ultrasonic spray pyrolysis, filling of carbon nanotubes, solution-processing, microwave-assisted aqueous synthesis, hydrothermal growth, conversion of Sb₂S₃ into SbSI (by physical vapor method and spinning coating SbI3 solution), as well as heat and laser formation of SbSI nanowires in chalcohalide glasses.
