Demonstrating and Unraveling a Controlled Nanometer-Scale Expansion of the Vacancy Defects in Graphene by CO2
Kumar Varoon Agrawal, Kuang-Jung Hsu, Luis Francisco Villalobos Vazquez de la Parra
A controlled manipulation of graphene edges and vacancies is desired for molecular separation, sensing and electronics applications. Unfortunately, available etching methods always lead to vacancy nucleation making it challenging to control etching. Herein ...
WILEY-V C H VERLAG GMBH2022PDC microfabrication through KOH-etched Si mould casting
The purpose of this project is to fabricate a mould etched by KOH for PDC casting and produce the fist PDC using this method. Casting for PDC is a known process, it has been done with PDMS moulds created from Si masters. Si moulds have also been fabricated ...
2021Study on the Performances of AlScN based SAW/BAW Hybrid Resonators A Parametric Analysis of Acoustic Wave Resonators with Large Figure of Merit
Luis Guillermo Villanueva Torrijo, Soumya Yandrapalli, Guilain Lionel Germain Lang
In this study, we analyze a 3rd type of FBAR's fundamental mode by finite element method. We show the importance of the substrate's wave velocity and conductivity on the electromechanical coupling efficiency. Then we demonstrate that etching traditional SA ...
IEEE2021Crystallization of gas-selective nanoporous graphene by competitive etching and growth: a modeling study
Kumar Varoon Agrawal, Soumajit Dutta
A robust synthesis methodology for crystallizing nanoporous single-layer graphene hosting a high density of size-selective nanopores is urgently needed to realize the true potential of two-dimensional membranes for gas separation. Currently, there are no c ...
