Heteroepitaxial growth of ZnO branches selectively on TiO2 nanorod tips with improved light harvesting performance.
In: Chemical communications, Vol. 47, No. 29: pp. 8400-8402
A seeded heteroepitaxial growth of ZnO nanorods selectively on TiO2 nanorod tips was achieved by restricting crystal growth on highly hydrophobic TiO2 nanorod film surfaces. Intriguing light harvesting performance and efficient charge transport efficiency has been found, which suggest potential applications in photovoltaics and optoelectronics.
