 | Tiwari, Ashutosh | Electrical properties of transparent and conducting Ga doped ZnO | In this paper, we report on the metal-semiconductor transition behavior observed in transparent and conducting ZnO:Ga films grown by pulsed-laser deposition. The electrical resistivity measurements were carried out on ZnO films with varying Ga concentration in the temperature range of 14 to 300 K. ... | Transparent conducting oxides; ZnO; Gallium; Metallic conductivity | 2006 |

 | Tiwari, Ashutosh | Epitaxial growth and properties of Zn1-xVxO diluted magnetic semiconductor thin films | Here we report systematic studies on the epitaxial growth and properties of Zn1−xVxO[x=0.001-0.2] thin films deposited onto sapphire c-plane single crystals. The thin films were deposited using pulsed laser deposition technique and were found to be epitaxial in nature. X-ray diffraction and high ... | ZnO; Vanadium | 2005 |

 | Tiwari, Ashutosh | Metallic conductivity and metal-semiconductor transition in Ga-doped ZnO | This letter reports the metallic conductivity in Ga:ZnO system at room temperature and a metal-semiconductor transition (MST) behavior at low temperatures. Zn0.95Ga0.05O films, deposited by pulsed laser deposition in the pressure range of ~10−2 Torr of oxygen, were found to be crystalline and exhi... | Transparent conducting oxides; ZnO; Gallium; Metallic conductivity | 2006 |

 | Tiwari, Ashutosh | Zn0.9Co0.1O-based diluted magnetic semiconducting thin films | Here we report a systematic study of structural, optical, and magnetic measurements on epitaxial Zn0.9Co0.1O films grown on c-plane sapphire single crystal, at various temperatures (500-650°C), using pulsed-laser deposition. The main emphasis in this work has been on the correlation of microstructu... | ZnO; Cobalt | 2004 |
