Web22 de nov. de 2016 · High-k dielectric ZrO 2 –TiO 2 nanocomposite was prepared using a simple Coprecipitation–calcination technique. X-ray diffraction shows that the synthesized nanocomposite showed monoclinic structure for ZrO 2 and orthorhombic structure for TiO 2. The SEM and TEM images show an average particle size of 20–30 nm. WebThe effect of TiO 2 high-k layer thickness on device sensitivity and fractional bandwidth was investigated experimentally, and both were seen to increase with the TiO 2 layer thickness, as expected. These latest devices with a TiO 2 layer were less sensitive than earlier devices with equivalent layers of HfO 2 high-k dielectric due to the lower breakdown voltage and …
