Electron spectroscopy measurements (UPS, XPS, and AES) of the heavy polyvalent liquid metals Hg, Tl, Pb and Bi reveal the systematic evolution of well separated 6s/6p bands with increasing widths of the bandgaps and increasing p bandwidths with increasing number of p electrons. The presence of...
As the atomic number increases from Cl to I, their band gaps become narrower from BiOCl (~3.2 eV) to BiOI (~1.7 eV), which falls into the responsive range of both UV and visible light. Due to its wide band gap, BiOCl usually demonstrates an excellent photocatalytic activity under UV ...

The local density approximation was used for exchange-correlation functional with a projector augmented-wave52 pseudopotentials, treating Bi 5d 6s 6p as valence electrons. The cut-off of the plane wave basis was set above 500 eV to guarantee that the absolute energies are converged to 1 ...
Formation of complexes with higher coordination number due to stereochemical role of the lone-pair of electrons is the striking aspect of bismuth which makes its structures different and complicated from its congeners (As and Sb). A detailed survey of synthetic strategies available in literature for...
Why we use a number of antimony-bismuth couples in a thermopile? Seebeck Effect German physicist Seebeck identified a potential difference across the ends of a conductor when the ends of the conductor are maintained at different temperatures. The free electrons at the hotter end of the conductor ...
two quasi-Fermi levels for electrons and holes are induced. The quasi-Fermi levels for electrons and holes move toward the conduction and valence bands, respectively, as light intensity rises, and an increasing number of traps become recombination sites. In result, the rising and fall times are...
The best performances of the samples prepared by the microwave treatment were attributed to the presence of a higher number of surface defects acting as traps for the photogenerated electrons. The hydrothermal method was used to synthesize Bi2MoO6 nanoplates that efficiently degraded RhB [311,312] ...
