Abstract:
Herein, we demonstrate the synthesis of a Bi2MoO6 nanorod array followed by the deposition of a BiVO4 absorber layer. This heterojunction yielded a photocurrent density of 250 μA cm(-2) at 0.8 VSCE, which is 21 times that produced by a planar Bi2MoO6 array under the same conditions. Moreover, in situ X-ray photoelectron spectroscopy clearly confirmed the improvement of the electron transport and charge separation afforded by the heterostructure, features that efficiently enhanced the photoelectrochemical properties of the array.

Schottky Barriers
Schottky barriers arise when a metal with a work function (Φm) contacts a semiconductor with a different work function (Φs). Initially, electrons transfer until the Fermi levels of the metal and semiconductor align at equilibrium. For instance, if Φm > Φs, the semiconductor Fermi level is higher than the metal's before contact. The...
