This paper presents the impact of parameter fluctuation due to process variation on radio frequency （RF） stability performance of double gate tunnel FET （DG TFET）. The influence of parameter fluctuation due to process variation leads to DG TFET performance degradation. The RF figures of merit （FoM） such as cut-off frequency （ft）, maximum oscillation frequency （fmax） along with stability factor for different silicon body thickness, gate oxide thickness and gate contact alignment are obtained from extracted device parameters through numerical simulation. The impact of parameter fluctuation of silicon body thickness, gate oxide thickness and gate contact alignment was found significant and the result provides design guidelines ofDG TFET for RF applications.

This article presents the bias and geometry optimization procedure for the radio frequency （RF） stability performance of nanoscale symmetric double-gate metal-oxide semiconductor field-effect transistors （DG- MOSFETs）. The stability model can provide hints for optimizing the DG-MOSFET under an RF range. The device parameters are extracted for different bias and geometry conditions through numerical simulation, and the RF figures of merit such as cut-off frequency （ft） and maximum oscillation frequency （fmax）, along with stability factor, are calculated for an optimized structure. The proposed structure exhibits good RF stability performance.

This study compares the accumulation of Cr（VI） and biochemical changes （total chlorophyll, carotenoid, protein, malondialdehyde （MDA） and cysteine contents） and roles of antioxidant enzymes （superoxide dismutase （SOD）, guaiacol peroxidase （GPX）, ascorbate peroxidase （APX）） in tolerance to metal induced stress in Cucumis utiUissimus L. grown in Cr contaminated soil （CS） with garden soil （GS）. Furthermore, Cr bioavailability was enhanced by ethylene diamine tetra-acetic acid （EDTA） addition to the soil to forecast the plant＇s accumulation pattern at elevated Cr environment. Accumulation of Cr in the leaves of the plant increased with increase in substrate metals concentration. It further increased with the addition of EDTA by 1437% and 487% in GS and CS, respectively at the highest treatment level. The lipid peroxidation increased proportionately with increase in Cr accumulation in the leaves. All the activity of antioxidant enzymes （SOD, GPX and APX） and the level of cysteine increased with dose dependant manner. SOD and cysteine were observed to be higher in the GS than in CS, but APX and GPX were found to be higher in CS than in GS, The increase in GPX and APX activities with the increase in Cr concentration could be assumed that these two enzymes have a major role in the defense mechanism towards stress induced by Cr in C. utillissimus.
