- Abstract
- Sol-gel processed ultrathin nanostructured SnO2 thin-film transistors were successfully fabricated on a SiO2 /Si substrate without using a self-aligned monolayer or high-k insulator, which may be unsuitable techniques for the commercial fabrication of complementary metal-oxide-semiconductors. The highest extracted field mobilitywas approximately 100cm(2)/V.s. In addition, by controlling the SnO2 film thickness, we successfully increased the on/off current ratio to similar to 107. The electrical performance of the proposed transistors is sufficient for high-resolution liquid crystal or organic light-emitting diode displays, which require a high field-effect mobility (>10 cm(2)/V.s) and high on/off current ratio (>106). Ultrathin SnO2 is also a promising rare-metal-free starting matrix for ternary and quaternary alloys, showing promising electric properties.
