        Impact of work function variation for enhanced electrostatic control with suppressed ambipolar behavior for dual gate L-TFET

        Singh Prabhat,Yadav Dharmendra Singh 한국물리학회 2022 Current Applied Physics Vol.44 No.-

        The favorable electrostatic potential and tunneling underneath the overall gate region, which prevents legitimate source to drain tunneling, controllability over the gate is assisted in vertical TFET configurations. An L-TFET (L-shaped Tunneling Field-Effect Transistor) has a larger tunneling length than a veritable TFET. As a consequence, the current in the on-state (Ion) has gotten better. The increased ambipolar current and low Ion/Ioff ratio of L-TFET will need to be tuned for low-power and high-frequency functionality. On the other hand, significantly worse switching performance and distortions may lead to a weak robust device. By establishing a high-k gate oxide-based drain underlap region with dual gate, this study is dedicated to ameliorating the Ion/Ioff by subverting ambipolar behavior. To investigate the impact of height of second gate (Hgate2) and work-function of this (WFgate2), EBD (Energy Band Diagram), electric field distribution in X and Y direction, potential and recombination rate are examined under various conditions. Which leads to enhanced DC/RF and linearity performance. Along with this, Current-Voltage characteristics, DC/RF, and linearity performance Figure of Merits (FOMs) also investigated the assessment of variation of Hgate2 and WFgate2, and it is optimized for the better suppression of Iambi (ambipolar current) with a steep slope in transfer characteristics. In addition to that, Current-voltage statistics (Ids - Vgs), DC/RF, and linearity efficiency FOMs were being used to assess the influence of changing the Hgate2 and WFgate2, which was modulated for greater Iambi suppression (ambipolar current) with improved SS and Vth for the proposed device.

        Effect of Acupressure on Pain during Inferior Alveolar Nerve Block Injection in Children Aged 5-10 Years Old - An Experimental Study

        Gurharikar Ayushi Shashikant,Nagpal Devendra,Yadav Prabhat Singh,Chaudhari Purva,Hotwani Kavita,Lamba Gagandeep 사단법인약침학회 2023 Journal of Acupuncture & Meridian Studies Vol.16 No.4

        Background: Acupressure, which is related to acupuncture, is a noninvasive therapy suitable for use in children. However, data examining acupressure’s effects on the pain of local anesthetic injection in children are sparse. Objectives: The purpose of this study was to evaluate acupressure’s effects on the pain of local anesthetic injection in children. Methods: This randomized, double-blind, parallel-group clinical study included 37 5- to 10-year-olds who had an inferior alveolar nerve block (IANB) for a mandibular extraction and were randomized to one of two groups: acupressure (study group) or non-acupressure (control group). The Wong-Baker FACES Pain Rating Scale (WBFPS) and the Sound, Eye, Motor (SEM) scale were utilized for subjective and objective pain assessment during injection. Results: The objective and subjective assessment of pain during injection significantly differed between the groups, with the acupressure group displaying lower scores. Conclusion: Acupressure at the extra one point (EX-HN1) reduced pain during IANB injection in 5- to 10-year-olds and can be used as an adjunct to conventional measures like topical anesthesia to reduce pain.
