We designed a new model tunnel field-effect transistor (TFET) based on Triple Heterojunction Tunnel Field Effect Transistor (THJ-TFET) is investigated and designed in this paper. This structure has a complex body with a metal oxide semiconductor field effect transistor. The integral switching mechanism of Triple Heterojunction TFET differs from conventional TFET and its construction, analytical modeling, and BTBT operations are well suitable for low power electronics. Here triple heterojunction (THJ) tunnel field-effect transistor (THJ-TFET) has been recommended to find the solution for less power usage test for new designs. The Triple Hetero junction TFET device is made up of semiconductors like silicon (Si), Silicon Dioxide (SiO2), Hafnium Oxide (HfO2), and Titanium Dioxide (TiO2) materials are very potential. The Triple Hetero Junction-Tunnel FET device layout with 60 nanometers dimensions and an overall gate length of 5 nm technology is used for the designing of the proposed device (THJ-TFET). The THJ-TFET structure is invented using the TCAD tool with a channel length of 5 nm innovations. Hence Triple Hetero Junction TFET device achieved 5% more drain current (Ion) and has calibrated all the analog parameters and RF parameters. [ABSTRACT FROM AUTHOR]

A novel gas sensor based on Ag-doped WO3 nanostructures was successfully deposited on a glass substrate via electron beam evaporation technique. The microstructure, surface morphology, chemical composition, crystal structure, and optical properties of the pure and Ag-doped WO3 nanostructure thin films were studied by scanning electron microscopy (SEM), atomic force microscopy (AFM), energy dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), X-ray diffractometer, and photoluminescence spectroscopy (PL). Gas-sensing tests revealed that the 15 wt% Ag-doped WO3 nanostructure possess excellent gas-sensing performance for ethanol. The sensitivity of the material toward 100 ppm ethanol was as high as 65 at an optimum operating temperature of 300 °C, which is higher than that of undoped WO3. The response/recovery times 9 s/11 s, great selectivity and outstanding long-term stability was obserevd for the 15 wt% Ag doped WO3 nanostructure sensor. The improvement of ethanol-sensing performance is related to the active space charge regions around the interface of Ag particles and WO3. [ABSTRACT FROM AUTHOR]
