  • Investigation of ITC Impact on Negative Bias HJVTFET for Implementing Universal Logic Gates

    The objective of this study is to examine how interface trap charges (ITC) influence the logic performance of a p‐type heterojunction vertical TFET structure without and with gate overlap (HJVTFET‐WOG and HJVTFET‐WG). The logic gates can be realized with the help of the HJ‐VTFET that uses germanium as the source material. Using HJVTFET‐WOG and HJVTFET‐WG structures, our simulations have proven that two‐input universal logic functions like NAND and NOR gates may be realized. By adjusting the gate‐source overlap region and choosing the right silicon body thickness, the suggested vertical TFET is able to perform logic operations. For verifying the universal gate functionality, the HJVTFET drain current characteristic and energy band diagram are analyzed by considering the effect of trapped charges. The tunneling width of logic functions is narrower when the ITC is positive and wider when it is negative, and the effective sub‐threshold slopes (SS) have been examined. It has been discovered that positive ITCs can enhance device capabilities, while negative ITCs lead to diminishing functionality. The suggested HJVTFET‐WOG structure is a promising structure for implementing the logic gates for digital application under the influence of interface trap charges because its electrical performance is less vulnerable to ITC than HJVTFET‐WG.

    The World Health Organization (WHO) has officially declared the international outbreak of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), often known as Coronavirus Disease 2019 (COVID-19), a global pandemic based on the significant and sudden increase in human infections worldwide. With suitable treatment and early diagnosis, this outbreak can be controlled to a certain extent. In the present research, the performance of a novel dielectrically modulated heterojunction-based splitgate double cavity vertical TFET biosensor for detecting SARS-CoV-2 with reference to the virus spike, DNA and envelope proteins has been thoroughly investigated. The suggested sensor’s sensitivity has been evaluated through the computation of the deviation in drain current. We model the hybridized biomolecules in the nanogaps as the dielectric constant equivalent of the viral proteins. Additionally, sensing speed and selectivity analysis pertaining to the various biomolecules are also investigated. The proposed sensor exhibits a notably high sensitivity (on the order of 108), high sensing speed, and high selectivity (on the order of 106), indicating its potential as a superior sensor. This study also examines the influence of variations in DNA charge density on the performance of the device. Ultimately, the proposed sensor is evaluated in comparison to its sensitivity and selectivity of a variety of FET-based biosensors previously documented in the literature.
