Analysis of novel transparent gate recessed channel (TGRC) MOSFET for improved analog behaviour

Abstract: In this paper, a novel device structure called transparent gate recessed channel MOSFET (TGRC-MOSFET) is proposed to alleviate the hot carrier effects for the advanced nanometer process. TGRC-MOSFET involving a recessed channel and incorporates indium tin oxide as a transparent gate. TCAD analysis shows that the performance of TGRC-MOSFET surpasses conventional recessed channel (CRC)-MOSFET in terms of high ION/IOFF ratio and better carrier transport efficiency in comparison to CRC-MOSFET. This simulation divulges the reduction in hot-carrier-effects metrics like electron velocity, electron temperature, potential, and electron mobility. Furthermore, the effect of gate length is observed on the analog behavior of TGRC-MOSFET. All the simulations have been done using DEVEDIT-3D and ATLAS device simulator. The work proposes the novel design for reduced hot carrier and low power switching applications.

Photocatalytic degradation of Amoxicillin in pharmaceutical wastewater: A potential tool to manage residual antibiotics

Abstract: The present study investigates the degradation of amoxicillin (AMX) using TiO2 photocatalysis and sono-photocatalysis in aqueous solution under UV-A (365 nm) and sunlight exposure. The photocatalysis, as well as sono-photocatalysis, were coupled with H 2 O2 as well to assess the improvement in the degradation of AMX. Response surface methodology (RSM) based on three-level and four variable Box–Behnken experiment design was used to analyse​ and validate the degradation of AMX. Upon comparison of observed values with predicted, the value of the coefficient of regression (R2) was 0.87 which indicate the good fit of the model. The optimum conditions for maximum degradation (80%) of AMX were AMX - 30mg/l, TiO2 dosage - 450mg/l, H 2 O2 concentration — 150 mg/l and pH — 7.0 under UV irradiation (672 W/m2). Significant improvement in rate kinetics of degradation was observed when photocatalysis was complemented with H 2 O2 and sonication (40 KHz) under optimized condition, but the maximal removal remained almost unaffected. The method proved efficient towards degradation of AMX in real pharmaceutical wastewater with reduced reaction time for targeted level treatment. It was concluded that photocatalysis is a potential method for degradation of AMX under the set optimized conditions, and it may be adopted in-silo since photocatalysis coupled with sonication becomes energy-prohibitive for degradation of AMX.
