“…The absorption band at 808 cm -1 can be assigned to the breathing mode of the triazine ring [21]. The infrared absorption bands at *528 cm -1 are attributed to the typical stretching modes of Bi-O [23]. Figure 5 depicts the concentration changes of RhB solution over g-C 3 N 4 /BiOX (X = Cl, Br, I) composite photocatalysts as a function of irradiation time.…”

g-C 3 N 4 /BiOX (X = Cl, Br, I) composite photocatalysts have been prepared by means of a facile immersion-hydrolysis method. The microstructural and morphological characteristics of the as-prepared composite photocatalysts were investigated by means of X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, and Fourier-transform infrared spectroscopy. The photodegradation performance of both g-C 3 N 4 /BiOCl and g-C 3 N 4 /BiOBr composites was superior to that of pure g-C 3 N 4 or the corresponding bismuth oxyhalides, possibly because of efficient separation of photogenerated carriers at the interface between g-C 3 N 4 and BiOX (X = Cl, Br). The photostability of as-prepared g-C 3 N 4 /BiOX (X = Cl, Br) composites was also investigated.

“…One can manipulate the superconducting density of states at the interface using photosensitive semiconductor/superconductor heterostructures. Bismuth oxyhalides BiOX (X = F, Cl, Br and I) photosensitive semiconductors that have attracted intensive attention due to their characteristic photoelectric properties and possible technological applications [5,6]. Due to their layered structure and facile fabrication by exfoliation [7], single crystals with thicknesses less than 1 µm could be used as a substrate for semiconductor/superconductor heterostructures.…”

Superconductivity of Niobium Thin Films in the BiOCl/Nb Heterostructures

In the current paper, electrical transport properties of 25 nm thick Nb films sputtered on the photosensitive semiconductor BiOCl were investigated in the temperature range 7.5 K ≤ T ≤ 8.5 K. The influence of green (532 nm) and red (640 nm) laser excitations on resistive superconducting transitions of the niobium thin films on a silicon glass and BiOCl single crystal substrates were studied. The temperature dependences of the resistivity for Nb are in good agreement with the McMillan model which indicates the strong influence of the inverse proximity effect induced by the interface. The increased influence of the BiOCl/Nb interface under laser excitation corresponds to the raising of the ratio of the density of normal to superconductivity carriers in the T → 0 limit and this observation is in agreement with the photoconductivity study of BiOCl single crystals.
