This paperwork includes a tunnelling transistor with dual gate and employing the use of dielectric modulation (DG-DM-JL-TFET) based structure. In order to recognize the biomolecule like protein, biotin, uricase etc a nano cavity is presented above the tunnelling. Charge plasma technique is used to form the drain and source regions into the substrate. High work function creates a hole in source and similarly a lower work function will create an electron in drain. The “N” region is etched into the substrate using hafnium electrode with a work function of 3.9 eV. Si02 of 0.5nm thickness is inserted between electrode of source. The “P+” region is etched on intrinsic silicon substrate using Platinum electrode having a work function of 5.93 eV. The device structure proposed in this paper shows results for sensitivity for charged and neutral biological molecules. The sensitivity of the biological molecules having higher dielectric constant is greater than those biological molecules possessing lower dielectric constant.

This manuscript presents a dielectric modulated doping-less dual metal Gate Tunnel Field Effect Transistor (DL-DMG-TFET) sensor. In which a nano-cavity is presented above the tunnelling point to recognize the bio-molecule like amino acids (AAs), protein, and so on the proposed P+ and N+ sections are invented relying on the electrode's work-function on silicon body. The impacts of metal work regulation, cavity length and thickness variety are investigated for improving band-to-band tunnelling probability at the source-channel intersection. The proposed structure shows perceptible affectability results for neutral and charged biomolecules. The sensitivity of the higher dielectric constant bio-molecules are higher as compared to bio-molecule having lower dielectric constant; the drain current sensitivity of the Gelatin (k=12) is assessed as which is 13% and 35% higher than the affectability of Keratin (k=10) and Bacteriophage T7 (k=5) separately at the nano-cavity length of 30 nm.

RS-4050 is a rigid epoxy based magnetic castable microwave absorbing material; it has been used in many areas of waveguide application as a microwave waveguide terminations and dummy loads. In recent years, there is a demand for composites material with lower dielectric constant higher loss factor for microwave application. This research, the effect of soda lime silica (SLS) on structural and complex permittivity of soda lime silica-high density polyethylene (SLS-HDPE) composites was conducted in order to explore the possibility of substituting RS-4050 with SLS-HDPE composites as a microwave waveguide terminations and dummy loads. Elemental weight composition of the SLS glass powder and HDPE was identified through scaling of different percentage of SLS and HDPE. X-ray diffraction (XRD) was used to investigate the crystallinity behavior of SLS-HDPE composites. The proposed SLS-HDPE composites material was studied at frequencies 8 to 12 GHz. The study was conducted using waveguide Agilent N5230A PNA technique. The effect of microwave frequency on complex permittivity properties for SLS-HDPE composites of different percentages of SLS and HDPE (10% SLS-90% HDPE, 20% SLS-80% HDPE, 30% SLS-70% HDPE, 40% SLS-60% HDPE, and 50% SLS-50% HDPE) were investigated. Results showed the diffraction patterns reveal good amorphous quality with a genuinely properties structure. The microwave frequency and composites percentages significantly influenced the complex permittivity (real and imaginary) properties of the composites. Moreover, the complex permittivity increased as the percentage of SLS filler increased in the host matrix HDPE as a result of increased in composite density due to less volume being occupied by the filler as the percentage increased. The complex permittivity of the smallest and largest percentages of SLS (10% and 50%) was (2.67-j0.05) and (3.45-j0.35), respectively. The study revealed that the best sample for waveguide application as microwave terminator is 50% SLS as it has the highest dielectric constant, highest loss factor, and highest loss tangent as compared to 10% SLS to 40% SLS. Also 50% SLS has the highest absorption properties as compare to 10% SLS, 20% SLS, 30% SLS, or 40% SLS. The XRD physical structure of the SLS-HDPE composites revealed the absorption characteristics of different percentages of the materials. The SLS-HDPE composites can be applied in the area of waveguide as a microwave waveguide terminations and dummy loads.

Xlpe Insulation

<p>Nowadays, XLPE cable has been widely used because it has better resistance than other cables. XLPE insulation has unique features including a high dielectric strength and high insulation resistance. A lot of researches based on hardware and software have been conducted to prove the effectiveness of XLPE cable such as AC and DC applications and Space Charge Distribution measurement under HVDC at High Temperature. This research focused on analysis of space charge and electric field on XLPE cable with effect of non-uniform contamination layer by using Quickfield Software. Non-uniform contaminations have been applied along XLPE cable using Arsenic Tribromide (AsBr3), Boron Bromide (BBr3), Ethylene Dichloride (CH2C1), Formic Acid (CH1O2), Formamide (CH3NO) and Alcohol element. Presence of these contamination elements represent of underground contamination. The size and layer of the contamination were non-uniform type. From the results, it is shown that lower dielectric constant of contamination will affect more on charge of XLPE insulation. As a conclusion, it can be seen lower dielectric constant value of contamination element greatly affecting the performance of XLPE insulation. Furthermore, size of contamination also influences the content of charge in contamination where the bigger the contamination size, the more charge contained in the contamination.</p>
