Surface pattern recording in amorphous chalcogenide layers

A review on solution processing of chalcogenide glasses for optical components

“…One way to combat the pore problem while retaining wettability on common substrates is to add 10% EDA to the propylamine solution [45]. EDAdissolved solution/gel is molecular in nature and forms polymeric amorphous networks upon annealing [12,23], without ammonium salt precipitation or gas evolution. Therefore, in solutions with 10% EDA, homogeneous films are obtained with no pores present (Fig.…”

“…Such properties have enabled many chalcogenide-based applications to be developed in diverse fields including photonics, medicine, environmental sensing and security [1][2][3]. Conventional methods for depositing these materials such as vacuum coating (thermal evaporation, chemical vapor deposition or sputtering) or pulse laser deposition [3][4][5][6][7][8][9][10][11][12] have been used extensively, and when combined with etching or other photolithography steps, these approaches are efficient for fabricating 2D structures on flat surfaces. However, they can become unpractical for producing structures with complicated shapes or special dimensions.…”

Electron beam induced surface modification of amorphous Sb2Se3 thin film

“…The non-linearity of the e-beam stimulated modification on exposition at high power (current) densities can be attributed to the heating effects [11]. The increase in temperature would influence not only the rate of charge and defect generation, but also the viscosity.…”

Ag2Se micropatterns via viscoelastic flow-driven phase separation

“…5 Evaporation through a mask also has been attempted to generate chalcogenide patterns. 6 Some groups adapted directed self-assembly of chalcogenide nanowires to prepare aligned structures on patterned substrates. [7][8][9] In this paper, we suggest a novel approach to prepare micropatterns of metal chalcogenides.…”
