“…In addition, similar observations were reported previously, 45 where the E g increased from 1.34 to 1.43 eV after Ag doping in SnS thin films. The same trends 67 have been observed for Cu-doped SnS thin films by other researchers. 68 A reduction in E g and red shift was also observed by Sebastian et al 69 for Al doping in SnS thin films, where the value of E g reduced from 1.5 to 1.29 eV.…”

“…Some of studies on Cu doped SnS lms which exist in the literature reported that Cu doping led to shrinkage in band gap of SnS lms until the certain Cu doping concentration and enlarged for further doping concentrations, regardless of the their crystal system [8,22,26,27]. Sebastian et al and Bommireddy et al stated that decrease in bad gap due to the increase in crystallite/grain size [22,26]. In this work variation in band gap may be related with the variation in crystallite size.…”

In this work undoped and Cu doped SnS lm at 4% and 8% were deposited onto glass substrates by spray pyrolysis technique in order to investigate the effect of Cu doping on their physical properties. Surface investigations showed that Cu doping reduced the surface roughness of SnS lms from 36.5 nm to 8.8 nm. XRD studies revealed that all lms have recently solved large cubic phase of SnS (p-SnS) with alattice of 11.53 Å and Cu doping led to reduction in crystallite size from 229 Å to 198 Å. Additionally, all deposited lms were found to be under compressive strain. Optical band gaps of SnS:Cu varied in the range of 1.83 eV-1.90 eV. Hall-effect measurements exhibited that all lm have p-type conductivity with low hole concentration (~10 11 -10 12 cm -3 ) and high electrical resistivity (~10 4 -10 5 Ωcm).

“…More magnesium atoms were positioned at the substitutional sites by increasing the doping concentration up to 10 atom %, which led to a successful integration of magnesium dopant into the SnS lattice and an increase in the occupied states and band gap. Similar results with doping in SnS with Cu, Pb, and Ag have been reported elsewhere. − …”

High-performance photodetection is becoming increasingly important for the advancement of technology. Very few materials are available that can respond to light across the ultraviolet to the infrared (IR) range. These materials are very much required for optoelectronic devices. Two-dimensional (2D) layered materials became relevant following the discovery of graphene. Transition-metal chalcogenides belong to the 2D layered material class, as well. The field of optoelectronic applications makes extensive use of them. The current study investigated the photodetector device by doping pure SnS nanoflakes with Fe, Mn, Mg, Pd, and W. These materials were used to create paper-based, flexible, biodegradable electronics through a solvent-free hand-print technique. The Mgdoped SnS photodetector has the highest photo response performance among the devices. With a specific detectivity value of 1.64 × 10 10 Jones and a responsivity value of 52 mA W −1 , the 7% Mg-doped SnS exhibits the best response among the different Mg doping. Extensive on−off cycles were used to assess the switching stability of the device, observing clear photo response and photoswitching behavior. The photoswitching curves of the device as created and the device after 8 months show an amazing degree of consistency, indicating the device's resilience in open-air environments. The device was bent repeatedly to test its twisting, foldability, and flexibility. It continuously displayed a definite photoswitching trend. Testing in a very basic and acidic environment verified the device's chemical stability, and its photo response and photoswitching functions remain functional. When the paperbased photodetector's thermal stability was examined at various temperatures, the findings demonstrated that the device continues to function normally and produce photocurrent. Considering how quickly technology is developing nowadays and how much waste is produced by electronics, switching to paper-based gadgets could help achieve sustainability goals.
