Titanium-doped zirconium oxide (mixed high-k) has been used as the gate oxide layer for the future generation metal oxide semiconductor devices. This mixed high-k layer was prepared by using Sol-Gel based spin-coated method. This mixed high-k layer’s chemical, structural, and initial electrical properties are investigated thoroughly. It is clearly confirmed that the suitable chemical composition and bond formation of the proposed mixed high-k layer from EDAX and FTIR analysis observations. The XRD spectra strengthened the presence of ZrTiO2. The measured dielectric constant of the proposed mixed high-k layer from the extracted C-V plots has been varying from 29.1 to 37.6 with respect to spin coating from 4000 to 6000 rpm. With lower spin rates, the leakage current is less.

The double gate MOSFET, where two gates are fabricated along the length of the channel one after another. Design of logic gates is one of the most eminent application of Double Gate MOSFET. Gallium nitride (GaN) based metal-oxide semiconductor field-effect transistors (MOSFETs) are shown to be promising for digital logic applications. This paper describes the design and analysis of different types of logic gates using GaN based DG-MOSFET. The gate length (LG) is kept constant at 10.6 nm. The gate voltage varies from 0 to 1 V for the device switching from turn OFF to turn ON-state. For the device with HfO2 as gate oxide, the ON-state current (ION) and OFF-state current (IOFF) are found 8.11×10-3 and 6.38605×10-9A/μm respectively. The leakage current is low for the device with HfO2 as compared to that for the device with ZrO2. The subthreshold swing (SS) is 68.7408 mV/dec for the device with HfO2.
