Modification of solution processed thin chalcogenide films composition by source solution doping

Comparison of solution processed As33S67 thin films deposited using primary amines of various aliphatic chain length

“…In comparison with physical vapor deposition methods, solution processed thin film deposition methods offer advantage in the possibility of source solution doping (e.g. : glass composition modification [12] or formation of composite material by introducing extrinsic materials such as nanoparticles [13]) and potential for large scale deposition and structuring by frequently used printing techniques. On the other hand, solution processed chalcogenide thin films usually contain residual amount of organic solvents influencing the thin films properties.…”

Optical and chemical properties of As–Se and As–S–Se solution processed thin films prepared via As50Se50 source solution modification

“…For this reason, both arsenic and chalcogen overstoichiometric glasses of As–S and As–Se systems have lower chemical resistance and lower glass transition temperature than stoichiometric ones. 19,31…”

“…The sulfur-modified samples exhibit 3–5 at% sulfur depletion for samples annealed at the highest temperatures due to the evaporation of non-bonded sulfur. 31…”

“…For this reason, both arsenic and chalcogen overstoichiometric glasses of As-S and As-Se systems have lower chemical resistance and lower glass transition temperature than stoichiometric ones. 19,31 The solution of the As 50 Se 50 chalcogenide glass in ethylenediamine (EDA) was modified by dissolving elemental sulfur and selenium directly in the glass solution. The chemical structure of the glass solutions was investigated using Raman spectroscopy.…”

Preparation of quaternary solution processed chalcogenide thin films using mixtures of separate As40S60 and Ge20Sb5S75 glass solutions

“…One of the major advantage of solution deposition route is the possibility to integrate different substances or materials to the glass solution or co-dissolution of chalcogenide glass and dopant material. Deposited thin films may have significantly modified physico-chemical properties [16,17] or some new additional properties can be introduced (e.g. photoluminescence or photoconductivity [18][19][20][21]).…”
