Preparation of Zn–In–S film electrodes using chemical bath deposition for photoelectrochemical applications

Photoelectrochemical study of ZnIn2Se4 electrodes fabricated using selenization of RF magnetron sputtered Zn–In metal precursors

“…Sample (e), which had the largest energy band gap, had the lowest photo-enhancement current density. Similar observations in PEC responses for ZnIn 2 S 4 were reported in the literature[22]. The ZnIn 2 Se 4 samples obtained using the reactive selenization process with the sputtering of ZneIn metal alloys are suitable for PEC application.…”

Unique band structure enhanced visible light photocatalytic activity of phosphorus-doped BiOI hierarchical microspheres

“…11d both of the samples are n-type semiconductors. 49 The at band potential (E  ) was determined by the extrapolation of the Mott-Schottky plot, and the E  of BiOI and 4% P-BiOI are found to be À1.49 and À1.83 V vs. Ag/AgCl electrode (À1.27 and À1.61 eV vs. the normal hydrogen electrode, NHE), 50,51 respectively. The E  is approximately equal to the E CB for n-type semiconductors, which means that the conduction band position of BiOI is 0.34 eV lower than that of 4% P-BiOI.…”

Effect of [Cu]/[Cu+In] ratio in the solution bath on the growth and physical properties of CuInS2 film using one-step electrodeposition

“…The conduction type and flat band potentials of a semiconductor can be measured in a variety of ways [4,38]. One way is to measure the open circuit potential of a sample under sufficiently intense illumination by photons with energy greater than its energy gap.…”
