摘要

The interface between bulk semiconductor and the metal is quite well understood. The formation of a space charge layer at the semiconductor-metal interface improves charge separation under bandgap excitation. However, the mere dimension of the semiconductor nanoparticles makes it difficult to extrapolate such a space charge model on the nanoscale. Metal nanoparticles or islands deposited on semiconductor surface play an important role in catalyzing interfacial charge transfer process. For example, in our earlier work a 3-5 fold improvement in the photoelectrochemical performance of nanostructured TiO_2 films was achieved by coupling them with noble metal nanoparticles. This observation also parallels the studies of Nakato and coworkers who reported an enhancement in the photovoltage by deposition of metal islands on single crystal semiconductors. Despite a large number of investigations reported in the literature, the factors responsible for improved performance in metal-semiconductor nanocomposites are yet to be understood fully.
